<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'>I have built my program with MPICH2 1.0.8p1 on Windows XP. My
input and output files are on mapped drives. I run the program on two different
Windows XP machines and get different behaviors. On one machine, I can run the
program with or without the –mapall option on mpiexec. On the other
machine, the program works only with the –mapall option. On both machines
the drives are always mapped at the OS level. Both machines are configured
identically as far as I can tell; in fact one was cloned from the other. For
supporting my users, I would like to understand why it works on one machine without
the –mapall option but not on the other. Where would I look for the
differences in configuration?<o:p></o:p></span></font></p>
