For MPI jobs: Remember that the total number of cores cannot be greater than the total number of chains MrBayes is using. For example, if you have 2 runs, each with 4 chains, the maximum number of cores to request is 2*4=8 cores. As long as the number of cores is under 12, it is best to keep nodes=1 (nodes = physical machines) as that will keep all communication within a single node. If you need more than 12 cores, you will probably want to add :infiniband to the request. (e.g. nodes=4:ppn=8:infiniband).

Description

mrbayes website  

MrBayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models. MrBayes uses Markov chain Monte Carlo (MCMC) methods to estimate the posterior distribution of model parameters.

Environment Modules

Run module spider mrbayes to find out what environment modules are available for this application.

System Variables

  • HPC_MRBAYES_DIR - installation directory

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.
