File becomes locked after initial run of Pelegant

Make sure the mpd ring is set properly if you use the pre-built version of Pelegant and the mpiexec is the desired one (e.g. which mpiexec).

Perfect! Apparently I have several versions of MPI installed! Doh!

Code: Select all

[smolloy@rowan RTMLCSR]$ which mpiexec
/usr/lib64/openmpi/1.2.7-gcc/bin/mpiexec
[smolloy@rowan RTMLCSR]$ locate mpiexec
/usr/bin/mpiexec
/usr/bin/mpiexec.py
/usr/lib/openmpi/1.2.7-gcc/bin/mpiexec
/usr/lib/openmpi/1.2.7-gcc/man/man1/mpiexec.1.gz
/usr/lib64/openmpi/1.2.7-gcc/bin/mpiexec
/usr/lib64/openmpi/1.2.7-gcc/man/man1/mpiexec.1.gz
/usr/share/doc/mpich2-1.0.8p1/www/www1/mpiexec.html
/usr/share/man/man1/mp-mpiexec.1.gz
/usr/share/man/man1/mpiexec.1.gz
/usr/share/mpich2/bin64/mpiexec

So I changed script to explicitly call the correct version of mpiexec,

Code: Select all

/usr/share/mpich2/bin64/mpiexec

And everything now appears to be working correctly.

Thanks for helping me debug this guys -- I really appreciate your time.

Also, it is better to have a large number of particles to use Pelegant efficiently.

Now that things are working, I'll be increasing the particle number to something statistically significant. I had it at that low number for debugging purposes.

Thanks again folks!
