<font size=2 face="sans-serif">Hello,</font>
<br>
<br><font size=2 face="sans-serif">I am running an MPI program on a machine
with two 16-core processors yet, no matter what configuration I use with
mpiexec, I am only receiving 4 simultaneous processes.</font>
<br><font size=2 face="sans-serif">I would like to maximize this machine's
potential and run 8 or 16 processes. I have tried all of the channel selections
and tried the -binding option.</font>
<br><font size=2 face="sans-serif">Since I need to specify a different
working directory for each process (due to many output files with naming
conflicts), I have a config file with 8 lines of the form:</font>
<br>
<br><font size=2 face="sans-serif">-n 1 -binding auto -dir <mydir01>
<myprog> <inpfile></font>
<br><font size=2 face="sans-serif">-n 1 -binding auto -dir <mydir02>
<myprog> <inpfile></font>
<br><font size=2 face="sans-serif">...etc</font>
<br>
<br><font size=2 face="sans-serif">and I run:</font>
<br>
<br><font size=2 face="sans-serif">mpiexec -configfile <filename></font>
<br>
<br><font size=2 face="sans-serif">Am I doing something wrong, or does
MPICH just know best and cannot run more than 4 jobs at a time on this
system?</font>
<br>
<br><font size=2 face="sans-serif">Thanks,</font>
<br>
