[mpich-discuss] Dual core problem

[Jayesh Krishna]

Hi,
 Can you cpi (c:\program files\mpich2\examples\cpi.exe) on your notebook ? 
 Does "mpiexec -n 3 hello.exe" work for you (mpiexec launches all procs on the localhost by default)?

Regards,
Jayesh

My version is 1.2.1p1. I have already tried the older as well as newer
versions of mpich2 but without success.

For job I use e.g.:
mpiexec –hosts 3 localhost localhost localhost hello.exe
this one works perfectly with the MPI code on my other PC.
I tried lots of others options which are correct (I always checked the
correctness on my other PC). From this I deducted that problem seems to be
in notebook not in the code. Funny is that in one of 4 cases the outputs
are correct.

My OS is 32bit WinXP Professional SP3, it is notebook HP Intel Core2 Duo CP.
