[mpich-discuss] seek help on mpi- mpich

[Jayesh Krishna]

Hi,
 Can you try running the example MPI program (cpi.exe) provided with MPICH2 using the following command ?

 mpiexec -machinefile mf0.txt -n 2 C:\Progra~1\MPICH2\examples\cpi.exe

Regards,
Jayesh

Hi, thanks.
I get what you said. but why my pc worker does'nt show anything that shows
something the worker's pc is printing/doing what master says to get work
done.


until this time...my pc cannot validate (mpiexec -validate)..
one more thing I configued using wmpiconfig, then i can see this 2
processors (from master)

C:\Documents and Settings\Administrator\My Documents\myPar>mpiexec
-machinefile mf0.txt -np 2 hostname
hpxp
ummuRifqi


~really messed..
