Batch Submission
A better approach is to submit a MrBayes task as a parallel batch submission to run across multiple nodes, an example of which is:
#!/bin/bash #SBATCH -J MrBTest # Job name, you can change it to whatever you want #SBATCH -N 4 # Number of nodes to run across #SBATCH -n 100 # Number of cores to run across #SBATCH -o %N-%j.log # Standard output will be written here #SBATCH -e %N-%j.err # Standard error will be written here #SBATCH -p compute # Slurm partition, where you want the job to be queued module add openmpi/gcc/1.10.5 mrbayes/gcc/3.2.6 mpirun -mca pml cm -mca mtl psm2 mb-mpi input_nex_file.nex
The options for mpirun are required to make use of the Omni-Path interconnect.
