Description

HPC Challenge is a benchmark suite that measures a range memory access
patterns. The HPC Challenge benchmark consists of basically 7 tests: 1)
HPL - the Linpack TPP benchmark which measures the floating point rate
of execution for solving a linear system of equations. 2) DGEMM -
measures the floating point rate of execution of double precision real
matrix-matrix multiplication. 3) STREAM - a simple synthetic benchmark
program that measures sustainable memory bandwidth (in GB/s) and the
corresponding computation rate for simple vector kernel. 4) PTRANS
(parallel matrix transpose) - exercises the communications where pairs
of processors communicate with each other simultaneously. It is a useful
test of the total communications capacity of the network. 5)
RandomAccess - measures the rate of integer random updates of memory
(GUPS). 6) FFT - measures the floating point rate of execution of double
precision complex one-dimensional Discrete Fourier Transform (DFT). 7)
Communication bandwidth and latency - a set of tests to measure latency
and bandwidth of a number of simultaneous communication patterns; based
on b_eff (effective bandwidth benchmark).
