HowToParallel
It is possible to run CLaMS on multi-processor machines using MPI or OpenMP.
On the Ubuntu machines is the PGF compiler suite installed that has MPICH implemented.
In the following a short How to:
First it is necessary to make the path of the MPI libraries public by executing:
for 64bit machines:
. /opt/pgi/linux86-64/8.0-2/mpi.sh
for 32bit machines:
. /opt/pgi/linux86/8.0-2/mpi.sh
Then compile the needed programs by executing:
make useMPI=true
Before running the CLaMS script or a single program you have to execute:
ssh-add
This is necessary, because the processes communicate per ssh.
The programs must be called as following:
mpirun -np # program # - number of processors
