Hi,
I would like to benchmark my computer before applying patches for the recent Intel fiasco.
Suggestions?
I have installed some. First I try with "interbench". Runs as root, in a terminal. Another I was going to try is this: hpcc-openmpi - A high performance computing benchmark tool The HPC Challenge benchmark consists of basically 7 tests: • HPL - the Linpack TPP benchmark which measures the floating point rate of execution for solving a linear system of equations. • DGEMM - measures the floating point rate of execution of double precision real matrix-matrix multiplication. • STREAM - a simple synthetic benchmark program that measures sustainable memory bandwidth (in GB/s) and the corresponding computation rate for simple vector kernel. • 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. • RandomAccess - measures the rate of integer random updates of memory (GUPS). • FFT - measures the floating point rate of execution of double precision complex one-dimensional Discrete Fourier Transform (DFT). • 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). But fails to run: Telcontar:~ # /usr/lib64/mpi/gcc/openmpi/bin/hpcc --help /usr/lib64/mpi/gcc/openmpi/bin/hpcc: error while loading shared libraries: libmpi.so.12: cannot open shared object file: No such file or directory But the lib is installed: Telcontar:~ # locate libmpi.so /usr/lib64/mpi/gcc/mvapich2/lib64/libmpi.so.12 /usr/lib64/mpi/gcc/mvapich2/lib64/libmpi.so.12.0.5 Telcontar:~ # l /usr/lib64/mpi/gcc/mvapich2/lib64/libmpi.so.12 /usr/lib64/mpi/gcc/mvapich2/lib64/libmpi.so.12.0.5 lrwxrwxrwx 1 root root 16 Jan 9 21:10 /usr/lib64/mpi/gcc/mvapich2/lib64/libmpi.so.12 -> libmpi.so.12.0.5* - -rwxr-xr-x 1 root root 4550096 Oct 18 2016 /usr/lib64/mpi/gcc/mvapich2/lib64/libmpi.so.12.0.5* Telcontar:~ # What's the problem? - -- Cheers, Carlos E.
