Yes, I've tried this. To eliminate questions about the machine name etc... I have<br><br>1. go through network setup wizards again to establish that the machine name is mb13 and the workgroup is LOGIC; disable firewall.<br>
(reboot)<br><br>1.5 Verify that I can share a folder on mb13, and from the other computer can successfully map a drive to \\mb13\sharename -- this establishes that mb13 is the recognized computer name. And that other computers can reach it at that name.<br>
<br>2. uninstall mpich2 completely<br>3. install mpich2<br>(reboot)<br><br>4. mpi -register, and provide username/password of an account on the machine that is a "computer administrator" (thomas)<br><br>I still am unable to simply run mpiexec -n 2 hostname.... I get the same "Credentials for thomas rejected connecting to mb13"<br>
<br>I am able to run 'smpd -status' and it tells me that smpd is running on mb13.<br><br>Good grief... (my build from source & testing on two bsd-based macs took about 15 minutes)<br><br>-thomas<br><br><div class="gmail_quote">

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>
