Latest version, 1.4.2, compiled and tested on an ArchLinux cluster 
using OpenMPI-1.8.4-1, You should also have numactl installed.


If you just execute "gmandel" you will create mpi processes and threads 
on the local host.

To run mpi processes across multiple hosts in the cluster, you should use
mpirun, for example,

$ mpirun -np 1 --bind-to core:overload-allowed --machine-file openmpi.hosts gmandel

The actual number of processes to use in each image generation is set from the
gmandel GUI. The "--bind-to core:overload-allowed" is used to allow
specification of more mpi processes than cores available, while 
"openmpi.hosts" is a file which contains the names of the hosts which 
make up the cluster.

With 5 ArchLinux boxes (30 cores) I've managed to get over 2500 MMIPS (mega mandel iterations per second).
