<P><FONT SIZE=2> Hi,<BR>
<BR>
# Can you ping the machines from each other ?<BR>
# Make sure that you have the same version of MPICH2 installed on both the machines.<BR>
# Do you have any firewalls (windows, third-party) running on the machines (Turn off any firewalls running on the machines)?<BR>
# 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).<BR>
# 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).<BR>

Let us know the results.<BR>

Subject: [mpich-discuss] unable to connect ?<BR>
<BR>
Hi<BR>
<BR>
I have two WinXp machines (10.0.0.13,10.0.0.10) with mpich2 installed, and on this command:<BR>
"D:\Program Files\MPICH2\bin\mpiexec.exe" -hosts 2 10.0.0.10 10.0.0.13 -noprompt c:\ex\cpi.exe<BR>
<BR>
I get:<BR>
<BR>
Aborting: unable to connect to 10.0.0.10<BR>
<BR>
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.<BR>
<BR>
regards<BR>
K.A. Albert<BR>
