windows - domain required?<BR></FONT><BR></DIV>
<DIV></DIV>Hello,<BR><BR>I have just subscribed to the list to ask a question
about mpich2 on windows. (I found the archives but don't see a way to
search them).<BR><BR>Is it a requirement that the windows computers
participating in mpich2 be part of a windows domain? I see things in the
documentation that perhaps imply this, but not state it outright.<BR><BR>My
computers are simply on a local network, and part of a "workgroup". The
smpd process manager can "see" the other systems to some extent, since the
result of<BR><BR>smpd -status mb13 // mb13 is the hostname of
my other windows pc<BR><BR>correctly finds that smpd is running on my other
host. But executing mpiexec and providing hostnames in a "machinefile"
e.g.<BR><BR>mpiexec -n 4 -machinefile machines echo %COMPUTERNAME%<BR><BR>fails
with:<BR><BR>Credentials for thomas rejected connecting to mb13<BR><BR><BR>I
have taken care that the username/pass is identical on each machine, the user is
admin, etc. I have followed steps I've found in various documents about
uninstalling/installing smpd and providing the identical passphrase on each,
running mpiexec -register, etc...<BR><BR>Any ideas? (Or is it just that I
must be running on a domain, which I cannot find concrete documentation
about)<BR><BR>thanks very much, <BR>thomas blom in austin, tx<BR></BODY></HTML>
