Re: "PARALLEL VERSION (UNIFIED) RUNNING IN SERIAL MODE USING SINGLE PROCESS", Why does not "in parallel"?

Hi,

there are several mistakes here.

First, you are using absolutely wrong command line syntax:

c:\gamesG\firefly.exe >%1.out c:\gamesG\ d:\gamesG\1 -p4gm 10000000 -i %1.inp -o %1.gms -r -f -b -np 2

It will not work nor with WMPI 1.3, nor with nt-mpich-sp (actually, the recommended option).

For nt-mpich-smp the correct syntax would be e.g.:

c:\gamesG\firefly.exe -i %1.inp -o %1.gms -r -f  c:\gamesG\ d:\gamesG\1 -np 2

Second, for standalone system, there is no need to install WMPI
at all. Moreover, this MPI implementation is very old and a bit
buggy. As mentioned in the documentation, in the case of standalone system,
it is way better to use NT-MPICH-SMP.

Regards,
Alex Granovsky
