Additional Information

For MPI jobs
  • As a rule of thumb ntasks should be set to the total number of chains (MrBayes default is 4 chains * 2 runs = 8 chains)
  • As long as the number of cores is under 12, it is best to use a single node ("SBATCH --nodes=1") where nodes are physical computers as that will keep all communication within a single node.
