<DIV>Hi Jayesh,</DIV>
<DIV> </DIV>
<DIV>Your assumption is correct. The command was mpiexec -hosts 2 images16
images17 cpi</DIV>
<DIV> </DIV>
<DIV>mpiexec -n 2 cpi.exe works fine </DIV>
<DIV> </DIV>
<DIV>Same error message if I use IP addresses instead of names for mpiexec
command</DIV>
<DIV> </DIV>
<DIV>I have attached the debug log for smpd and the verbose log for the mpiexec
as requested.</DIV>
<DIV> </DIV>
<DIV>I have just put 2+2 together and noticed that you put together the
development manual for the MPICH2. </DIV>

<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I am running XP Pro on the machines and am therefore using smpd. As far
as I know the mpd is used in the unix/linux environment. The smpd is
operational on both PCs. The local check for the status os the smpd on either
machine shows that they are running. When i do a remote check with smdp
I get the same message.i.e. </DIV>
<DIV> </DIV>
<DIV>smpd -status <remotehostname></DIV>
<DIV>abort: unable to connect to <remotehostname></DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
