[Beowulf] For CPMD users

Hi CPMD users,

 With a CPMD parallel job, I'm getting a Segmentation Fault error.

Let me explain what I did.

   Installed MPICH with Intel Compilers. Configure looks as follows:

./configure --prefix=/opt/MPI_LIBS/MPICH-Intel
-cc=/opt/intel/cce/10.1.008/bin/icc
-fc=/opt/intel/fce/10.1.008/bin/ifort --enable-f77 --with-device=ch_p4
--with-arch=LINUX


 When I run a CPMD job with 1-4 proceses, the job is getting killed and
gives following error:

# mpirun -machinefile /export/M4 -np 4 ./cpmd.x
/opt/APPLICATIONS/CPMD/singlemol.input > single4.out
Killed by signal 2.
forrtl: error (69): process interrupted (SIGINT)
Killed by signal 2.
Killed by signal 2.

If only one process is used and without redirection, the following error
occurred:

p0_16857:  p4_error: interrupt SIGSEGV: 11

Can anybody explain what might be the cause for this?

regards,
Sangamesh
