Hi:

I'm new to this group.  I'm trying to implement a parallel quantum code called "Seqquest".
I'm trying to figure out why there is an error in the implementation of this code where there is an error:

          This job has allocated 2 cpus

*** End of error message ***
^@mpiexec: Warning: task 0 died with signal 11 (Segmentation fault).

Trying to debug this code, I noticed that the math library is an Intel math library, but all of the codes including scalapack and blacs were compiled using GNU compiler.  Will there be compatibility issues?
