Hi…
I have installed pgi compiler under the /opt/pgi/ and mpich in /opt/pgi/linux86-64/9.0/mpi/mpich/
it is work fine at one process but when we debug on multi processes then these problems occur …
When we compile the program than no problem -
pgCC -g -o mpi_allgather_3 mpi_allgather_3.cpp -lmpich
when we give the command to run and debug the program–
mpirun -dbg=pgdbg -np 5 /home/plasma/pgi_examples/mpi_allgather_3 &
then pgi compiler open but when we press the continue button than these problems occured .
PGDBG Program I/O-
execvp:No such file or Directory
pgdbg> libnss_files.so.2 loaded by ld-linux-x86-64.so.2.

Warning!!! The current implementation of PGDBG supports
the debugging MPI application with randomized loading by
duplicating symbol information for each process. If
PGDBG is consuming too much memory, you should consider
running:
sysctl -w kernel.randomize_va_space=0
