and size<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>My program in Tomography was actually working well on several
cluster pcs before when I was using (mpich.nt.1.2.5.). But
I got a problem with ranking and size after I installed MPICH2 1.0.3, and
uninstalled it since MPICH2 1.0.3. gave me error messages.</DIV>
<DIV> </DIV>
<DIV>There are the details:</DIV>
<DIV>When I use mpich.nt.1.2.5., it gives me rank and size like 44468690 or
such a minus number (all the pcs are the same rank and the same size). I
checked all the configuration and installed it again, but it is still this
problem. I am using Digital Visual Fortran. </DIV>
<DIV> </DIV>
<DIV>Could you tell me how can I fix this problem?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
