The test command suggested (mpiexec -n 2 hostname) works fine on one of the machines. On the other machine (both are winXP) I get the error:<br><br>Credentials for thomas rejected connecting to mb13<br>Aborting: Unable to connect to mb13<br>
<br>This is the result of just running locally, not over a network! In answer to the previous question, 'thomas' is not a domain user. This is just two winXP machines on a local network that are part of the same "workgroup" but neither are part of any domain. <br>
<br>I wonder if this has to do with my having changed the machine name on mb13 ... but I have since completely uninstalled and installed mpich2. I left the default phrase "behappy" during this installation. I then ran wmpiregister and entered my username and password (which I use to login to each machine sucessfully).<br>
<br>I have tried to play with wmpiconfig, but it is a little difficult to understand how to use this. I don't find any documentation for it.<br><br>Thanks very much for any help....<br><br>-thomas blom, austin tx<br>

windows - domain required?<br></font><br></div><div><div></div><div class="Wj3C7c">
<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></div></div></div>
