High Productivity Computing Systems ( HPCS ) is a DARPA project for developing a new generation of economically viable high productivity computing systems for national security and industry in the 2002–10 timeframe; an extenuated research specialization that's from High-Performance Computing Systems .
8-505: The HPC Challenge (High-performance computers challenge) is part of the project. An HPCS goal is to create a multi petaflop systems. Also (status unknown from official site): A vivid description of this type of work was given by James Bamford in his March 15, 2012 article: The plan was launched in 2004 as a modern-day Manhattan Project. Dubbed the High Productivity Computing Systems program, its goal
16-530: A new secret war. But this time, instead of a bomb of almost unimaginable power, the weapon is a computer of almost unimaginable speed. HPC Challenge Benchmark HPC Challenge Benchmark combines several benchmarks to test a number of independent attributes of the performance of high-performance computer (HPC) systems. The project has been co-sponsored by the DARPA High Productivity Computing Systems program,
24-563: The United States Department of Energy and the National Science Foundation . The performance of complex applications on HPC systems can depend on a variety of independent performance attributes of the hardware. The HPC Challenge Benchmark is an effort to improve visibility into this multidimensional space by combining the measurement of several of these attributes into a single program. Although
32-471: The nodes of the system). The benchmark currently consists of 7 tests (with the modes of operation indicated for each): At a high level, the tests are intended to provide coverage of four important attributes of performance: double-precision floating-point arithmetic (DGEMM and HPL), local memory bandwidth (STREAM), network bandwidth for "large" messages (PTRANS, RandomAccess, FFT, b_eff), and network bandwidth for "small" messages (RandomAccess, b_eff). Some of
40-405: The notation used by the benchmark reports, results labeled "single" mean that the test was run on one randomly chosen processor in the system, results labeled "star" mean that an independent copy of the test was run concurrently on each processor in the system, and results labeled "global" mean that all the processors were working in coordination to solve a single problem (with data distributed across
48-504: The performance attributes of interest are not specific to any particular computer architecture, the reference implementation of the HPC Challenge Benchmark in C and MPI assumes that the system under test is a cluster of shared memory multiprocessor systems connected by a network . Due to this assumption of a hierarchical system structure most of the tests are run in several different modes of operation. Following
56-512: The southwestward-flowing Clinch River bends sharply to the southeast. About 25 miles from Knoxville, it is the "secret city" where uranium- 235 was extracted for the first atomic bomb. A sign near the exit read: what you see here, what you do here, what you hear here, when you leave here, let it stay here . Today, not far from where that sign stood, Oak Ridge is home to the Department of Energy's Oak Ridge National Laboratory, and it's engaged in
64-471: Was to advance computer speed a thousandfold, creating a machine that could execute a quadrillion (10) operations a second, known as a petaflop—the computer equivalent of breaking the land speed record. And as with the Manhattan Project, the venue chosen for the supercomputing program was the town of Oak Ridge in eastern Tennessee, a rural area where sharp ridges give way to low, scattered hills, and
