OpenMP ( Open Multi-Processing ) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C , C++ , and Fortran , on many platforms, instruction-set architectures and operating systems , including Solaris , AIX , FreeBSD , HP-UX , Linux , macOS , and Windows . It consists of a set of compiler directives , library routines , and environment variables that influence run-time behavior.
72-405: OpenMP is managed by the nonprofit technology consortium OpenMP Architecture Review Board (or OpenMP ARB ), jointly defined by a broad swath of leading computer hardware and software vendors, including Arm , AMD , IBM , Intel , Cray , HP , Fujitsu , Nvidia , NEC , Red Hat , Texas Instruments , and Oracle Corporation . OpenMP uses a portable , scalable model that gives programmers
144-646: A GPU , fixed-function implemented on field-programmable gate arrays (FPGAs), and fixed-function implemented on application-specific integrated circuits (ASICs). Hardware acceleration is advantageous for performance , and practical when the functions are fixed, so updates are not as needed as in software solutions. With the advent of reprogrammable logic devices such as FPGAs, the restriction of hardware acceleration to fully fixed algorithms has eased since 2010, allowing hardware acceleration to be applied to problem domains requiring modification to algorithms and processing control flow . The disadvantage, however,
216-459: A register file ). Hardware accelerators improve the execution of a specific algorithm by allowing greater concurrency , having specific datapaths for their temporary variables , and reducing the overhead of instruction control in the fetch-decode-execute cycle. Modern processors are multi-core and often feature parallel "single-instruction; multiple data" ( SIMD ) units. Even so, hardware acceleration still yields benefits. Hardware acceleration
288-687: A business aiming to generate a profit for its owners. A nonprofit organization is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. Depending on the local laws, charities are regularly organized as non-profits. A host of organizations may be nonprofit, including some political organizations, schools, hospitals, business associations, churches, foundations, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt , and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as
360-424: A delegate structure to allow for the representation of groups or corporations as members. Alternatively, it may be a non-membership organization and the board of directors may elect its own successors. The two major types of nonprofit organization are membership and board-only. A membership organization elects the board and has regular meetings and the power to amend the bylaws. A board-only organization typically has
432-554: A fiscally viable entity. Nonprofits have the responsibility of focusing on being professional and financially responsible, replacing self-interest and profit motive with mission motive. Though nonprofits are managed differently from for-profit businesses, they have felt pressure to be more businesslike. To combat private and public business growth in the public service industry, nonprofits have modeled their business management and mission, shifting their reason of existing to establish sustainability and growth. Setting effective missions
504-740: A general-purpose central processing unit (CPU). Any transformation of data that can be calculated in software running on a generic CPU can also be calculated in custom-made hardware, or in some mix of both. To perform computing tasks more efficiently, generally one can invest time and money in improving the software, improving the hardware, or both. There are various approaches with advantages and disadvantages in terms of decreased latency , increased throughput , and reduced energy consumption . Typical advantages of focusing on software may include greater versatility, more rapid development , lower non-recurring engineering costs, heightened portability , and ease of updating features or patching bugs , at
576-471: A low-stress work environment that the employee can associate him or herself positively with. Other incentives that should be implemented are generous vacation allowances or flexible work hours. When selecting a domain name , NPOs often use one of the following: .org , the country code top-level domain of their respective country, or the .edu top-level domain (TLD), to differentiate themselves from more commercial entities, which typically use .com . In
648-457: A nonprofit entity without having tax-exempt status. Key aspects of nonprofits are accountability, integrity, trustworthiness, honesty, and openness to every person who has invested time, money, and faith into the organisation. Nonprofit organizations are accountable to the donors, founders, volunteers, program recipients, and the public community. Theoretically, for a nonprofit that seeks to finance its operations through donations, public confidence
720-478: A program parallelized using OpenMP on a N processor platform. However, this seldom occurs for these reasons: Some vendors recommend setting the processor affinity on OpenMP threads to associate them with particular processor cores. This minimizes thread migration and context-switching cost among cores. It also improves the data locality and reduces the cache-coherency traffic among the cores (or processors). A variety of benchmarks has been developed to demonstrate
792-697: A self-selected board and a membership whose powers are limited to those delegated to it by the board. A board-only organization's bylaws may even state that the organization does not have any membership, although the organization's literature may refer to its donors or service recipients as 'members'; examples of such organizations are FairVote and the National Organization for the Reform of Marijuana Laws . The Model Nonprofit Corporation Act imposes many complexities and requirements on membership decision-making. Accordingly, many organizations, such as

#1732797843181864-614: A simple and flexible interface for developing parallel applications for platforms ranging from the standard desktop computer to the supercomputer . An application built with the hybrid model of parallel programming can run on a computer cluster using both OpenMP and Message Passing Interface (MPI), such that OpenMP is used for parallelism within a (multi-core) node while MPI is used for parallelism between nodes. There have also been efforts to run OpenMP on software distributed shared memory systems, to translate OpenMP into MPI and to extend OpenMP for non-shared memory systems. OpenMP
936-479: A single FPGA or ASIC. Similarly, specialized functional units can be composed in parallel, as in digital signal processing , without being embedded in a processor IP core . Therefore, hardware acceleration is often employed for repetitive, fixed tasks involving little conditional branching , especially on large amounts of data. This is how Nvidia 's CUDA line of GPUs are implemented. As device mobility has increased, new metrics have been developed that measure
1008-471: A strong vision of how to operate the project, try to retain control of the organization, even as new employees or volunteers want to expand the project's scope or change policy. Resource mismanagement is a particular problem with NPOs because the employees are not accountable to anyone who has a direct stake in the organization. For example, an employee may start a new program without disclosing its complete liabilities. The employee may be rewarded for improving
1080-581: A wide diversity of structures and purposes. For legal classification, there are, nevertheless, some elements of importance: Some of the above must be (in most jurisdictions in the US at least) expressed in the organization's charter of establishment or constitution. Others may be provided by the supervising authority at each particular jurisdiction. While affiliations will not affect a legal status, they may be taken into consideration by legal proceedings as an indication of purpose. Most countries have laws that regulate
1152-399: Is a factor in the amount of money that a nonprofit organization is able to raise. Supposedly, the more a nonprofit focuses on their mission, the more public confidence they will gain. This will result in more money for the organization. The activities a nonprofit is partaking in can help build the public's confidence in nonprofits, as well as how ethical the standards and practices are. There
1224-461: Is a key for the successful management of nonprofit organizations. There are three important conditions for effective mission: opportunity, competence, and commitment. One way of managing the sustainability of nonprofit organizations is to establish strong relations with donor groups. This requires a donor marketing strategy, something many nonprofits lack. Nonprofit organizations provide public goods that are undersupplied by government. NPOs have
1296-399: Is an implementation of multithreading , a method of parallelizing whereby a primary thread (a series of instructions executed consecutively) forks a specified number of sub -threads and the system divides a task among them. The threads then run concurrently , with the runtime environment allocating threads to different processors. The section of code that is meant to run in parallel
1368-439: Is an important distinction in the US between non-profit and not-for-profit organizations (NFPOs); while an NFPO does not profit its owners, and money goes into running the organization, it is not required to operate for the public good. An example is a club, whose purpose is its members' enjoyment. Other examples of NFPOs include: credit unions, sports clubs, and advocacy groups. Nonprofit organizations provide services to

The OpenMP parallel for flag tells
SECTION 20
#17327978431811584-557: Is concerned. In many countries, nonprofits may apply for tax-exempt status, so that the organization itself may be exempt from income tax and other taxes. In the United States, to be exempt from federal income taxes, the organization must meet the requirements set forth in the Internal Revenue Code (IRC). Granting nonprofit status is done by the state, while granting tax-exempt designation (such as IRC 501(c) )
1656-475: Is done by processing Boolean functions on the binary input, and then outputting the results for storage or further processing by other devices. Because all Turing machines can run any computable function , it is always possible to design custom hardware that performs the same function as a given piece of software. Conversely, software can always be used to emulate the function of a given piece of hardware. Custom hardware may offer higher performance per watt for
1728-453: Is granted by the federal government via the IRS. This means that not all nonprofits are eligible to be tax-exempt. For example, employees of non-profit organizations pay taxes from their salaries, which they receive according to the laws of the country. NPOs use the model of a double bottom line in that furthering their cause is more important than making a profit, though both are needed to ensure
1800-442: Is limited in parallel processing capability only by the area and logic blocks available on the integrated circuit die . Therefore, hardware is much more free to offer massive parallelism than software on general-purpose processors, offering a possibility of implementing the parallel random-access machine (PRAM) model. It is common to build multicore and manycore processing units out of microprocessor IP core schematics on
1872-422: Is marked accordingly, with a compiler directive that will cause the threads to form before the section is executed. Each thread has an ID attached to it which can be obtained using a function (called omp_get_thread_num() ). The thread ID is an integer, and the primary thread has an ID of 0 . After the execution of the parallelized code, the threads join back into the primary thread, which continues onward to
1944-408: Is not classifiable as another category. Currently, no restrictions are enforced on registration of .com or .org, so one can find organizations of all sorts in either of those domains, as well as other top-level domains including newer, more specific ones which may apply to particular sorts of organization including .museum for museums and .coop for cooperatives . Organizations might also register by
2016-424: Is overhead to decoding instruction opcodes and multiplexing available execution units on a microprocessor or microcontroller , leading to low circuit utilization. Modern processors that provide simultaneous multithreading exploit under-utilization of available processor functional units and instruction level parallelism between different hardware threads. Hardware execution units do not in general rely on
2088-474: Is that in many open source projects, it requires proprietary libraries that not all vendors are keen to distribute or expose, making it difficult to integrate in such projects. Integrated circuits are designed to handle various operations on both analog and digital signals. In computing, digital signals are the most common and are typically represented as binary numbers. Computer hardware and software use this binary representation to perform computations. This
2160-411: Is the remuneration package, though many who have been questioned after leaving an NPO have reported that it was stressful work environments and the workload. Public- and private-sector employment have, for the most part, been able to offer more to their employees than most nonprofit agencies throughout history. Either in the form of higher wages, more comprehensive benefit packages, or less tedious work,
2232-476: Is unique in which source of income works best for them. With an increase in NPOs since 2010, organizations have adopted competitive advantages to create revenue for themselves to remain financially stable. Donations from private individuals or organizations can change each year and government grants have diminished. With changes in funding from year to year, many nonprofit organizations have been moving toward increasing

2304-1125: Is used to specify number of threads for an application. OpenMP has been implemented in many commercial compilers. For instance, Visual C++ 2005, 2008, 2010, 2012 and 2013 support it (OpenMP 2.0, in Professional, Team System, Premium and Ultimate editions), as well as Intel Parallel Studio for various processors. Oracle Solaris Studio compilers and tools support the latest OpenMP specifications with productivity enhancements for Solaris OS (UltraSPARC and x86/x64) and Linux platforms. The Fortran, C and C++ compilers from The Portland Group also support OpenMP 2.5. GCC has also supported OpenMP since version 4.2. Compilers with an implementation of OpenMP 3.0: Several compilers support OpenMP 3.1: Compilers supporting OpenMP 4.0: Several Compilers supporting OpenMP 4.5: Partial support for OpenMP 5.0: Auto-parallelizing compilers that generates source code annotated with OpenMP directives: Several profilers and debuggers expressly support OpenMP: Pros: Cons: One might expect to get an N times speedup when running

Private charitable contributions increased for the fourth consecutive year in 2017 (since 2014), at an estimated $ 410.02 billion. Out of these contributions, religious organizations received 30.9%, education organizations received 14.3%, and human services organizations received 12.1%. Between September 2010 and September 2014, approximately 25.3% of Americans over
2448-596: The Wikimedia Foundation , have formed board-only structures. The National Association of Parliamentarians has generated concerns about the implications of this trend for the future of openness, accountability, and understanding of public concerns in nonprofit organizations. Specifically, they note that nonprofit organizations, unlike business corporations, are not subject to market discipline for products and shareholder discipline of their capital; therefore, without membership control of major decisions such as

Relying on a common cache for code and data leads to the "von Neumann bottleneck", a fundamental limitation on the throughput of software on processors implementing the von Neumann architecture. Even in the modified Harvard architecture , where instructions and data have separate caches in the memory hierarchy , there
2592-572: The server industry, intended to prevent regular expression denial of service (ReDoS) attacks. The hardware that performs the acceleration may be part of a general-purpose CPU, or a separate unit called a hardware accelerator, though they are usually referred to with a more specific term, such as 3D accelerator, or cryptographic accelerator . Traditionally, processors were sequential (instructions are executed one by one), and were designed to run general purpose algorithms controlled by instruction fetch (for example, moving temporary results to and from
2664-549: The C/C++ specifications being released in 2002. Version 2.5 is a combined C/C++/Fortran specification that was released in 2005. Up to version 2.0, OpenMP primarily specified ways to parallelize highly regular loops, as they occur in matrix-oriented numerical programming , where the number of iterations of the loop is known at entry time. This was recognized as a limitation, and various task parallel extensions were added to implementations. In 2005, an effort to standardize task parallelism
2736-455: The NPO's reputation, making other employees happy, and attracting new donors. Liabilities promised on the full faith and credit of the organization but not recorded anywhere constitute accounting fraud . But even indirect liabilities negatively affect the financial sustainability of the NPO, and the NPO will have financial problems unless strict controls are instated. Some commenters have argued that
2808-464: The OpenMP directive. The different types of clauses are: Used to modify/check the number of threads, detect if the execution context is in a parallel region, how many processors in current system, set/unset locks, timing functions, etc A method to alter the execution features of OpenMP applications. Used to control loop iterations scheduling, default number of threads, etc. For example, OMP_NUM_THREADS
2880-701: The OpenMP system to split this task among its working threads. The threads will each receive a unique and private version of the variable. For instance, with two worker threads, one thread might be handed a version of i that runs from 0 to 49999 while the second gets a version running from 50000 to 99999. Variant directives are one of the major features introduced in OpenMP 5.0 specification to facilitate programmers to improve performance portability. They enable adaptation of OpenMP pragmas and user code at compile time. The specification defines traits to describe active OpenMP constructs, execution devices, and functionality provided by an implementation, context selectors based on
2952-461: The age of 16 volunteered for a nonprofit. In the United States, both nonprofit organizations and not-for-profit organizations are tax-exempt. There are various types of nonprofit exemptions, such as 501(c)(3) organizations that are a religious, charitable, or educational-based organization that does not influence state and federal legislation, and 501(c)(7) organizations that are for pleasure, recreation, or another nonprofit purpose.

3024-649: The appropriate country code top-level domain for their country. In 2020, nonprofit organizations began using microvlogging (brief videos with short text formats) on TikTok to reach Gen Z, engage with community stakeholders, and overall build community. TikTok allowed for innovative engagement between nonprofit organizations and younger generations. During COVID-19, TikTok was specifically used to connect rather than inform or fundraise, as its fast-paced, tailored For You Page separates itself from other social media apps such as Facebook and Twitter. Some organizations offer new, positive-sounding alternative terminology to describe
3096-401: The best of the newly minted workforce. It has been mentioned that most nonprofits will never be able to match the pay of the private sector and therefore should focus their attention on benefits packages, incentives and implementing pleasurable work environments. A good environment is ranked higher than salary and pressure of work. NPOs are encouraged to pay as much as they are able and offer
3168-565: The community; for example aid and development programs, medical research, education, and health services. It is possible for a nonprofit to be both member-serving and community-serving. Nonprofit organizations are not driven by generating profit, but they must bring in enough income to pursue their social goals. Nonprofits are able to raise money in different ways. This includes income from donations from individual donors or foundations; sponsorship from corporations; government funding; programs, services or merchandise sales, and investments. Each NPO
3240-426: The construct in parallel. The original thread will be denoted as master thread with thread ID 0. Example (C program): Display "Hello, world." using multiple threads. Use flag -fopenmp to compile using GCC: Output on a computer with two cores, and thus two threads: However, the output may also be garbled because of the race condition caused from the two threads sharing the standard output . Whether printf
3312-439: The cost of overhead to compute general operations. Advantages of focusing on hardware may include speedup , reduced power consumption , lower latency, increased parallelism and bandwidth , and better utilization of area and functional components available on an integrated circuit ; at the cost of lower ability to update designs once etched onto silicon and higher costs of functional verification , times to market, and
3384-400: The cost of general-purpose utility. Greater RTL customization of hardware designs allows emerging architectures such as in-memory computing , transport triggered architectures (TTA) and networks-on-chip (NoC) to further benefit from increased locality of data to execution context, thereby reducing computing and communication latency between modules and functional units. Custom hardware
3456-402: The diversity of their funding sources. For example, many nonprofits that have relied on government grants have started fundraising efforts to appeal to individual donors. Most nonprofits have staff that work for the company, possibly using volunteers to perform the nonprofit's services under the direction of the paid staff. Nonprofits must be careful to balance the salaries paid to staff against
3528-432: The election of the board, there are few inherent safeguards against abuse. A rebuttal to this might be that as nonprofit organizations grow and seek larger donations, the degree of scrutiny increases, including expectations of audited financial statements. A further rebuttal might be that NPOs are constrained, by their choice of legal structure, from financial benefit as far as distribution of profit to members and directors
3600-474: The end of the program. By default, each thread executes the parallelized section of code independently. Work-sharing constructs can be used to divide a task among the threads so that each thread executes its allocated part of the code. Both task parallelism and data parallelism can be achieved using OpenMP in this way. The runtime environment allocates threads to processors depending on usage, machine load and other factors. The runtime environment can assign
3672-475: The establishment and management of NPOs and that require compliance with corporate governance regimes. Most larger organizations are required to publish their financial reports detailing their income and expenditure publicly. In many aspects, they are similar to corporate business entities though there are often significant differences. Both not-for-profit and for-profit corporate entities must have board members, steering-committee members, or trustees who owe
SECTION 50
#17327978431813744-469: The final directive from variants and context. Since OpenMP is a shared memory programming model, most variables in OpenMP code are visible to all threads by default. But sometimes private variables are necessary to avoid race conditions and there is a need to pass values between the sequential part and the parallel region (the code block executed in parallel), so data environment management is introduced as data sharing attribute clauses by appending them to
3816-416: The latest version/s. The core elements of OpenMP are the constructs for thread creation, workload distribution (work sharing), data-environment management, thread synchronization, user-level runtime routines and environment variables. In C/C++, OpenMP uses #pragmas . The OpenMP specific pragmas are listed below. The pragma omp parallel is used to fork additional threads to carry out the work enclosed in
3888-511: The money paid to provide services to the nonprofit's beneficiaries. Organizations whose salary expenses are too high relative to their program expenses may face regulatory scrutiny. A second misconception is that nonprofit organizations may not make a profit. Although the goal of nonprofits is not specifically to maximize profits, they still have to operate as a fiscally responsible business. They must manage their income (both grants and donations and income from services) and expenses so as to remain
3960-447: The need for more parts. In the hierarchy of digital computing systems ranging from general-purpose processors to fully customized hardware, there is a tradeoff between flexibility and efficiency, with efficiency increasing by orders of magnitude when any given application is implemented higher up that hierarchy. This hierarchy includes general-purpose processors such as CPUs, more specialized processors such as programmable shaders in
4032-445: The nonprofit sector today regarding newly graduated workers, and to some, NPOs have for too long relegated hiring to a secondary priority, which could be why they find themselves in the position many do. While many established NPOs are well-funded and comparative to their public sector competitors, many more are independent and must be creative with which incentives they use to attract and maintain people. The initial interest for many
4104-550: The number of threads based on environment variables , or the code can do so using functions. The OpenMP functions are included in a header file labelled omp.h in C / C++ . The OpenMP Architecture Review Board (ARB) published its first API specifications, OpenMP for Fortran 1.0, in October 1997. In October the following year they released the C/C++ standard. 2000 saw version 2.0 of the Fortran specifications with version 2.0 of
4176-411: The organization a fiduciary duty of loyalty and trust. A notable exception to this involves churches , which are often not required to disclose finances to anyone, including church members. In the United States, nonprofit organizations are formed by filing bylaws, articles of incorporation , or both in the state in which they expect to operate. The act of incorporation creates a legal entity enabling
4248-452: The organization to be treated as a distinct body (corporation) by law and to enter into business dealings, form contracts, and own property as individuals or for-profit corporations can. Nonprofits can have members, but many do not. The nonprofit may also be a trust or association of members. The organization may be controlled by its members who elect the board of directors , board of governors or board of trustees . A nonprofit may have
4320-511: The organization's sustainability. An advantage of nonprofits registered in the UK is that they benefit from some reliefs and exemptions. Charities and nonprofits are exempt from Corporation Tax as well as the trustees being exempt from Income Tax. There may also be tax relief available for charitable giving, via Gift Aid, monetary donations, and legacies. Founder's syndrome is an issue organizations experience as they expand. Dynamic founders, who have
4392-550: The public and private sectors have enjoyed an advantage over NPOs in attracting employees. Traditionally, the NPO has attracted mission-driven individuals who want to assist their chosen cause. Compounding the issue is that some NPOs do not operate in a manner similar to most businesses, or only seasonally. This leads many young and driven employees to forego NPOs in favor of more stable employment. Today, however, nonprofit organizations are adopting methods used by their competitors and finding new means to retain their employees and attract
SECTION 60
#17327978431814464-483: The receipt of significant funding from large for-profit corporations can ultimately alter the NPO's functions. A frequent measure of an NPO's efficiency is its expense ratio (i.e. expenditures on things other than its programs, divided by its total expenditures). Competition for employees with the public and private sector is another problem that nonprofit organizations inevitably face, particularly for management positions. There are reports of major talent shortages in
4536-656: The relative performance of specific acceleration protocols, considering characteristics such as physical hardware dimensions, power consumption, and operations throughput. These can be summarized into three categories: task efficiency, implementation efficiency, and flexibility. Appropriate metrics consider the area of the hardware along with both the corresponding operations throughput and energy consumed. Examples of hardware acceleration include bit blit acceleration functionality in graphics processing units (GPUs), use of memristors for accelerating neural networks , and regular expression hardware acceleration for spam control in

Hardware description languages (HDLs) such as Verilog and VHDL can model the same semantics as software and synthesize the design into a netlist that can be programmed to an FPGA or composed into the logic gates of an ASIC. The vast majority of software-based computing occurs on machines implementing the von Neumann architecture , collectively known as stored-program computers . Computer programs are stored as data and executed by processors . Such processors must fetch and decode instructions, as well as load data operands from memory (as part of
4680-478: The sector in its own terms, without relying on terminology used for the government or business sectors. However, use of terminology by a nonprofit of self-descriptive language that is not legally compliant risks confusing the public about nonprofit abilities, capabilities, and limitations. Hardware acceleration Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on
4752-570: The sector. The term civil society organization (CSO) has been used by a growing number of organizations, including the Center for the Study of Global Governance . The term citizen sector organization (CSO) has also been advocated to describe the sector – as one of citizens, for citizens – by organizations including Ashoka: Innovators for the Public . Advocates argue that these terms describe
4824-489: The traditional domain noted in RFC 1591 , .org is for "organizations that didn't fit anywhere else" in the naming system, which implies that it is the proper category for non-commercial organizations if they are not governmental, educational, or one of the other types with a specific TLD. It is not designated specifically for charitable organizations or any specific organizational or tax-law status, but encompasses anything that

If needed calculations are specified in a register transfer level (RTL) hardware design, the time and circuit area costs that would be incurred by instruction fetch and decoding stages can be reclaimed and put to other uses. This reclamation saves time, power, and circuit area in computation. The reclaimed resources can be used for increased parallel computation, other functions, communication, or memory, as well as increased input/output capabilities. This comes at
