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>
