Resolving The Problem
How do I recompile linpack using openmpi 1.1.4 with gcc, pgf77 as backend compilers for mpicc and mpif77?
Prerequisite:
1. Open-MPI 1.1.4 is compiled with GCC and pgf77. Please refer to knowledge base article KB1-10OVHX for the intruction for the how to.
2. Portland Group Fortran Compiler is installed in the cluster
The procedure is as follow:
1- download linpack :
wget http://www.netlib.org/benchmark/hpl/hpl.tgz
2- copy a makefile from the setup directory (and rename):
cp setup/Make.Linux_ATHLON_FBLAS Make.amd_pgi_ompi_acml
3- edit and modify the Makefile (Attached):
Please note that we used the ACML library (non threaded) provided by portland.
4- make the distribution :
make arch=amd_pgi_ompi_acml
A binary named xhpl and the configuration file for linpack HPL.dat will be created here (under the hpll directory):
bin/amd_pgi_ompi_acml
5- edit the HPL.dat and run a basic example.
