That's really strange! I cannot reproduce this.

As Firefly was linked with MPICH2 1.4, I decided to check it with mpich2 v. 1.5.

To check, I have compiled mpich2 1.5 on one of our CentOS boxes
(it's rather old system so the kernel version is patched 2.6.18).
I have picked up the latest mpich2 1.5 source code from official
site (the tarball is dated October 8, 2012). I have compiled it
using:


./configure --prefix=/opt/mpich2-1.5-gcc32 CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 FCFLAGS=-m32 --enable-shared

make; make install


The compiler was gcc version 4.1.2 20071124 (Red Hat 4.1.2-42)
(as C++ and Fortran libraries are not used by Firefly, this is the
only relevant compiler).

I have got a lot of libraries in /opt/mpich2-1.5-gcc32/lib
There was no libmpich.so.3 library so I created it as a symbolic
link to libmpich.so.8  

Then I ran Firefly using /opt/mpich2-1.5-gcc32/bin/mpiexec and got it running perfectly.  

Could it be the case there is some library conflict with
your installation of mpich2? Did you perhaps get some part
of the output in the file or there were no output at all?
What is the output of

./firefly -nompi

command?

Kind regards,
Alex
