[maker-devel] Why doesn't MAKER use all the cores when I run it on an instance?

[Carson Holt]

The -cpu option is only for BLAST. However, if you run MAKER under MPI (even on a single machine), you can parallelize all steps. Set cpu=1 when running under MPI, otherwise BLAST will multiply the -cpu value with the MPI value, and oversubscribe the CPU.
