I install pgi cd under /hptc_cluster/pgi, so the mpich (mpich1) is under /hptc_cluster/pgi/linux86-64/7.2/mpi/mpich/
but when I tried to debug a mpi application with :
mpirun -machinefile machinefile -np 4 -dbg=pgdbg ./turb

it allways stoped at mpi_init, and the command pannel said:

I tried to see the message queue window, it said:
ERROR: unable to load /hptc_cluster/pgi/linux86-64/7.2/mpi/mpich/lib/libtvmpich.so: libpgc.so: cannot open shared object file: No such file or directory
Aborting message queue dump.

In fact, this application is able to run with 4 processes:
/hptc_cluster/pgi/linux86-64/7.2/mpi/mpich/bin/mpirun -machinefile machinefile -np 4 ./turb

Where is the question? Thanks very much.

Hi sad,

The MPICH and MPICH-2 libraries that accompany the PGI CDK can be used by PGDBG. The problem here is that the PGI runtime library "libpgc.so" is either not installed on one or more of your nodes, or you need to set "LD_LIBRARY_PATH" to include the location of this library.

I think I have already exported this libpgc.so, it is in:
/hptc_cluster/pgi/linux86-64/7.2-2/libso
I export LD_LIBRARY_PATH in .bashrc:
#for pgi
PGI=/hptc_cluster/pgi
LM_LICENSE_FILE=$LM_LICENSE_FILE:/hptc_cluster/pgi/license.dat

#for pgi
PATH=/hptc_cluster/pgi/linux86-64/7.2-2/bin:$PATH
LD_LIBRARY_PATH=/hptc_cluster/pgi/linux86-64/7.2-2/libso/libpgc.so:/hptc_cluster/pgi/linux86-64/7.2-2/lib:/usr/lib64:$LD_LIBRARY_PATH

#for pgdbg
PGDBG_MQS_LIB_OVERRIDE=/hptc_cluster/pgi/linux86-64/7.2/mpi/mpich/lib/libtvmpich.so
export PGI LM_LICENSE_FILE PGDBG_MQS_LIB_OVERRIDE
export PATH
export LD_LIBRARY_PATH

==========
I will try again, anyhow.Thanks, Mat.

Hi Sad,

Your LD_LIBRARY_PATH should only include directories. Try changing:
