HPC Challenge

HPC Challenge benchmark consists of 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 - a useful test of the total communication 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 test for simultaneous communication patterns. http://icl.cs.utk.edu/hpcc
