Windows<BR></FONT><BR></DIV>
<DIV></DIV>We downloaded MPICH2 installed on a windows XP machine. Although the
OS is Mac but we have VMware Fusion to access Windows. we created a Fortran code
(using Microsoft Visiual Studio) that runs on this machine and gives speed-up
factor of 2 (almost) for two processors. When we run this code for the first
time it asked for administrator user name and password, once we provide that it
works. From here we get an MPI executable.<BR>Now we take to to another computer
with the same setup (or the one with Windows XP as OS). We added the MPI bin
file to the environment variables. On the command line, I did
following<BR>mpiexec -remove<BR>mpiexec -register (provided a new user name and
password)<BR>now when I type <BR>mpiexec -validate --> it gives
(FAIL)<BR><BR>and I try to run my code it gives following
error.<BR><BR>Credentials for gulshan rejected connecting to
gulshan-0160b12<BR>Aborting: Unable to connect to gulshan-0160b12<BR><BR>I am
not sure what I am suppose to do. Can anyone help me with
this.<BR><BR>Gulshan<BR></BODY></HTML>
