<DIV></DIV>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:

not over a network! In answer to the previous question, 'thomas' is not

<BR><BR>I wonder if this has to do with my having changed the machine name on

wmpiregister and entered my username and password (which I use to login to

[mpich-discuss] mpich2 1.0.8 on windows - domain
required?<BR></FONT><BR></DIV>
<DIV>
<DIV></DIV>
<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></DIV></DIV></DIV></BLOCKQUOTE></DIV><BR></DIV></DIV></DIV></BLOCKQUOTE></DIV><BR></BODY></HTML>
