+== Open MPI ==
+
+OpenMPI is an implementation of the MPI (Message Passing Interface). It is used by some software for implementing parallel solutions. Examples include mpi versions of [Software/MrBayes MrBayes] and [Software/AmpliconNoise AmpliconNoise].
+
+Generic instructions can be found on: http://www.openmpi.org/
+
+=== Mykopat Grid specifics ===
+
+MPI enabled programs are launched through sge with a batch file similar to this one (modify for your specific software):
+
+{{{
+#!/bin/sh
+
+# Batch file for launching mpi tasks. Submit tasks with: qsub <name of this file>
+
+# Transfer current environment to job
+#$ -V
+
+# Ask for 4 parallel slots (currently at most 8)
+#$ -pe openmpi 4
+
+# Request run time (modify this!! and memory per task, total memory usage will be number of tasks times this request)
+#$ -l h_rt=1:0:0,h_vmem=1G
+
+
+# Launch the program with mpirun
+mpirun <my_program> <options_to_my_program>
