[mpich-discuss] trouble installing MPICH2 on Windows7-64

[Jayesh Krishna]

Hi,
 Can you run an MPI program from command prompt (Try running the example program cpi.exe provided with MPICH2. "mpiexec -n 2 C:\Progra~1\MPICH2\examples\cpi.exe")?

Regards,
Jayesh

Hello folks, I'm having difficulties, and would greatly appreciate your
advice. I have a medium-level machine with a Core 2 Duo processor running
Windows 7 64. I'd like to get mpich2 running, and be able to use the
appropriate R modules to take advantage of the fact that I have a 2-core
CPU. Unfortunately, MPICH2 isn't working for me.

The story: Today, I downloaded the 64-bit Windows installer for the most
recent stable release of MPICH2. I then carried out a vanilla install
process: log onto my computer as administrator, double-click the .msi, made
sure to choose to install for everyone, and add the location of the MPICH2
binaries to PATH. I started the wmpiconfig GUI, registered the
administrator account info, and when the config utility opened, I clicked
'get settings'. After a few seconds, the GUI complained "error =
inpsamo-psrmmw1: MPICH2 not installed or unable to query the host.'

I'm certain that MPICH2 is installed and running. The services tab on the
Task Manager clearly says so. I uninstalled MPICH2, and reinstalled from a
command prompt window (rather than double-clicking). Same problem. I tried
removing and reregistering the administrator account, and then also tried
my personal account. Same problem. I disabled my security software
(Symantec), carried out some further removing/registering/clickingaround.
Same problem.

I'm stumped. Any ideas?
