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>
