[MPICH] p4 error

[Sangamesh B]

Hi All,


     A cpmd parallel job which is compiled with MPICH( MPICH is compiled
with ifort 10) gave 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


But a CPMD serial job works fine.


Can any one tell me what p4_error, SIGINT, SIGSEGV mean?

Regards,
Sangamesh
