Definition
HPC Challenge (HPCC) is a benchmark that measures computer performance on various computational kernels that span the memory access locality space. HPCC includes tests that are able to take advantage of nearly all available floating point performance: High Performance LINPACK and matrix–matrix multiply allow for data reuse that is only bound by the size of large register file and fast cache. The twofold benefit from these tests is the ability to answer the question how well the hardware is able to work around the “memory wall” and how today’s machines compare to the systems of the past as they are cataloged by the LINPACK Benchmark Report [3] and TOP500. HPCC also includes other tests, STREAM, PTRANS, FFT, RandomAccess – when they are combined together they span the memory access locality space. They are able to reveal the growing inefficiencies of the memory subsystem and how they are addressed in the new computer infrastructures. HPCC also offers scientific rigor to the...
