Install ML Prerequisites

Building or installing prerequisites should be done in a directory created under the /home/solution-user/ directory. It is recommended to create a temporary folder called “src” so that it can be deleted easily after successful validation.

Note: Building from source should be done ONLY on an Edge node, not on a DataNode!

mkdir src
cd src

A development version of MPI will be required on the machine where you build the source code; only a runtime engine is required on the nodes in the ML pipeline. The solution has been tested on MPICH 3.1.4 mpi and the Intel MPI Library 5.1 intel-mpi. Please refer to the specific release documentation for full installation steps.

Install MPICH 3.1.4

#Pre-requisites
sudo yum -y groupinstall "Development Tools"

#create directories, be sure to keep the src in the mpich-install path
mkdir -p /home/oni/mpich-install/src
mkdir -p /home/oni/src/tmp/mpich-3.1.4
cd /home/oni/mpich-install/src
wget http://www.mpich.org/static/downloads/3.1.4/mpich-3.1.4.tar.gz
tar xvf mpich-3.1.4.tar.gz

#continued on next page
cd /home/oni/src/tmp/mpich-3.1.4/
/home/oni/mpich-install/src/mpich-3.1.4/configure -prefix=/home/oni/mpich-install/ |& tee c.txt
make |& tee m.txt
