Installing MrBayes for MPI and 64-bit
Let the home page describe what it is about (in the worst possible English): "MrBayes is a program for the Bayesian estimation of phylogeny. Bayesian inference of phylogeny is based upon a quantity called the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes's theorem. The posterior probability distribution of trees is impossible to calculate analytically; instead, MrBayes uses a simulation technique called Markov chain Monte Carlo (or MCMC) to approximate the posterior probabilities of trees."
Sourcefiles for MrBayes can be downloaded with a familiar process of extracting (
tar xvf mrbayes-3.1.2.tar.gz) into an appropriate location (e.g.,
/usr/local/src/MRBAYES/mrbayes/3.1.2. Installing MrBayes should be just the matter of typing
make but for MPI there is a number of modifications required top the Makefile and the sourcecode.
Firstly, edit the Makefile, set MPI=yes
Secondly, patch the sourcecode (patch -p 1 filename.patch) in the order listed. Download the patch files in an appropriate directory.
- Fix problem with SumP hanging in MPI on error: mrbayes-3.1.2-fix-sump-mpi.diff
- Change mcmcdiagn default to NO: mrbayes-3.1.2-fix-mcmcdiagn-disable.diff
- For 64-bit architecture, apply mb_64bit_safe.patch and compile with parameter _64BIT=yes. When applying this patch, use -R (the patch is in reverse format).
So, step by step:
Copy the patches into an appropriate directory
Add the patches
patch -p 1 patch -R -p 1
Find the right acml library and add it the path
Run the make
module load openmpi-gcc
OBJECT_MODE=64 make _64BIT=yes
