HPC Challenge Benchmark Results

3:38 pm in Lists by CSS

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).
