Re: Problem of using NM on Server

hi Jia,

from your description it is not 100% clear to me what you want to do, i.e.
do you want to parallelize a single run to multiple threads, or do you want
to run a bootstrap in parallel (with each run on a single thread). The
latter should work out-of-the box, just run e.g. 'bootstrap -threads=5
run1.mod' (from Pirana or command line).

The former scenario requires installation of MPI software (MPICH2), or you
can use the (slower) FPI option. Please see the NM7.3 manual for more info.
After this is installed, you will be able to parallelize single NONMEM runs
to multiple threads using nmfe or PsN. For either nmfe or PsN you will need
a "parafile" in which you define some settings for your system. Example
parafiles are provided in the NONMEM manual, but can be auto-generated from
Pirana too: you would just select "auto-MPI" in the nmfe/PsN dialog, and
the number of nodes, and it will generate the parafile for you and start
the run.

Hope this helps,
