mpiwini8.pnm can handle any number of nodes (cores) as long as they are on =
a single computer. Its default setting is 8 nodes, but you can specify [n=
odes]=20 on the command line to over-ride this. Or, modify the [nodes]=
= line in the pnm file under the $DEFAULTS section.

Dear All,

I have a large dataset and trying to use parallelization using default mpi =
option in NONMEM 7.3. The current mpiwini8.pnm is working fine but I want t=
o increase number of -nodes (PSN) to 20 to be more efficient. My understand=
ing is that the current pnm file has upper limit for 8 nodes. Could you ple=
ase help me on how to increase the nodes by modifying pnm file or any other=
 option? I appreciate your help.
