[maker-devel] question about Maker-MPI

[Carson Holt]

MAKER parallelizes at multiple levels. For the ab initio predictors, it will run multiple contigs simultaneously (so each one will get their own ab initio predictor running). For large contigs it will further divide it into 10Mb chunks, and each will run simultaneously.
