I am doing a dissertation which is due in two months time, which is
about benchmarking performance of DSM vs MPI and I want to include a
parallel alpha-beta pruning test case.
Do you know any Othello engines written in MPI (for Network of
Workstations or Grid) that I can download from the internet
l try to help you
out.

I wish to compile openmpi-1.2.2 so that it:
- support MPI_THREAD_MULTIPLE
- enable profiling (generate gmon.out for each process after my client app
finish running) to tell apart CPU time of my client program from the MPI
library
- static linking for everything (incl client app and all components
Hi!
You are already there. the fact that MPI_Thread_init only provide
MPI_THREAD_SINGLE shows that MPI_THREAD_MULTIPLE is NOT enabled in the
library binary that you're using. Although MPI_THREAD_MULTIPLE is
implemented in the library source code, it is only lightly tested, so it is
not enabled
se_modex_recv(). In line 144, we iterate over each received
address. It shouldn't be too hard for "Code Master" to write the
ports into a file.

I run my openmpi-based application in a multi-node cluster. There is also a
sniffer computer (installed with wireshark) attached to a listener port on
the switch to sniff any packets.
However I would like to know the protocol (UDP or TCP) as well as the ports
used by openmpi for interprocess com
How can I profile the communication of MPI library such as number of
messages sent / received, UDP packet requested to receive and sent and
volume of data sent?

I am a newbie in openmpi. I have just compiled a program with -g -pg (an
mpi program with a listener thread, which all MPI calls except
initialization and MPI_Finalize are placed within) and I run it. However
it crashes and I can't find any core dump, even I set the core dump max size
to 10
