Hi,
 Are you sure that you have 32-bit version of XP (and not 64-bit) installed in your system ?

(PS: AFAIK, Core 2 duos support both 32-bit and 64-bit versions of windows)
Regards,
Jayesh

Hi,

>1) Uninstall MPICH2 on your machine.
>2) Install mpich2-1.2.1p1 on your machine (Make sure that your OS is
32-bit before installing 32-bit version of MPICH2 - Start->Control
Panel->System)

This did not help, the same results.

>3) Re-compile C:\program files\mpich2\examples\icpi.c (cpi.vcproj)
Done

>4) Run "smpd -status" to get the status of smpd
"smpd running on oo7note"
oo7note is name of my notebook

>5) Try running cpi.exe as "c:\progra~1\mpich2\bin\mpiexec.exe -n 2
c:\progra~1\mpich2\examples\cpi.exe"

Unfortunately, the same results like before; only in one of 6 cases the
program runs correctly.

>6) Run "smpd -version" to get the version of the process manager.

"1.2.1p1"

>7) Type "winver" at the command prompt to get the complete version of
your OS.

"Microsoft Windows
Version 5.1 Service Pack 3 (2600.xpsp_sp3_gdr.091208-2036)"

I do not know what else I could try.

Ladislav
