Seattle: Building and running HPL

Pre-Requisits

The default O/S image provided by AMD is very minimal and doesn't include many packages at all. The following should be installed:

yum groupinstall 'Development Tools'

yum install tar bzip2 bc g++

Install OpenMPI

Either install from the repos openmpi, build it manually of choose an alternative MPI.

yum install openmpi openmpi-devel

Set up user environment

# add to the end of your ~/.bashrc
export PATH=$PATH:/usr/lib64/openmpi/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/openmpi/lib;/usr/include/openmpi-aarch64/

Download & build ATLAS

Download ATLAS from: [1]

Extract the contents of the tarball:

wget http://downloads.sourceforge.net/project/math-atlas/Stable/3.10.1/atlas3.10.1.tar.bz2

cd /root/scratch
tar jxvf atlas3.10.1.tar.bz2

Build ATLAS. N.B. - This will take a long time. On our sample Seattle system this took in excess of 5 hours. It is worth running the build process in a screen session or with nohup.

cd /root/scratch
mkdir atlas3.10.1_build
cd atlas3.10.1_build/
/root/scratch/ATLAS/configure --prefix=/opt/atlas/3.10.1
make 
make check
