[mpich-discuss] unable to connect ?

[Jayesh Krishna]

 Hi,
 
# Can you ping the machines from each other ?
# Make sure that you have the same version of MPICH2 installed on both the
machines.
# Do you have any firewalls (windows, third-party) running on the machines
(Turn off any firewalls running on the machines)?
# Make sure that you have the MPICH2 process manager, smpd.exe, running as
a service on both the machines (To check the status of the process manager
type, smpd -status, at the command prompt).
# Before trying to execute an MPI program like cpi.exe, try executing a
non-MPI program like hostname on the machines (mpiexec -hosts 2 10.0.0.10
10.0.0.13 hostname).

 Let us know the results.

(PS: In your reply please copy-paste the commands and the output)
Regards,
Jayesh

Hi

  I have two WinXp machines (10.0.0.13,10.0.0.10) with mpich2 installed,
and on this command:
"D:\Program Files\MPICH2\bin\mpiexec.exe" -hosts 2 10.0.0.10 10.0.0.13
-noprompt c:\ex\cpi.exe

I get:

Aborting: unable to connect to 10.0.0.10

Somehow I can't start any process on the remote machine(10.0.0.10). It
annoys me, that a few days ago it worked, but I had to reinstall one of
them, and since then i couldn't figure it out what's wrong with my
settings.  thanks.

regards
K.A. Albert
