Also i was wondering whether gdb could be used with openMPI. I know about -d option in mpirun but i need to use gdb if its possible. I think i have done all the necessary things to enable profiling and debuging but i am missing something here. Sorry guys i forgot i could debug shared library function in gdb. :) So currently using $ mpirun -np 1 xterm -e gdb hello to debug the openMPI source. If only i could get the profiling information, it could help me a lot.

Earlier i also saw a thread [http://www.open-mpi.org/community/lists/users/2008/04/5369.php] which talks about using --enable-mpi-profile option in configure which i have done. But i have not been able to get hold of profiling data. I tried installing vampir from https://computing.llnl.gov/code/vgv.html#installations but i am not been able to install. So i wanted to know how people are profiling the core openMPI code. I am a complete newbie and would appreciate any information. Also i was wondering whether gdb could be used with openMPI. I know about -d option in mpirun but i need to use gdb if its possible. I think i have done all the necessary things to enable profiling and debuging but i am missing something here. Currentl y i am configuring openMPI using following param ./configure -enable-debug --with-devel-headers --enable-trace --enable-mpi-profile --enable-mem-debug Leo P. ________________________________ Explore and discover exciting holidays and getaways with Yahoo!
