Hi everyone,
I am trying to understand the openMPI code so was trying to enable debug and
profiling by issusing
$ make "CFLAGS=-pg -g"
But i am getting this error.
libtool: link: ( cd ".libs" && rm -f "mca_paffinity_linux.la" && ln -s
"../mca_paffinity_linux.la" "mca_paffinity_linux.la" )
ma
Open MPI novice - but you may want
to try the addition of the --enable-debug configure option. That is, for
example:
./configure --enable-debug; make
Hope this helps.

Own a website.Get an unlimited package.Pay next to nothing.*Go to
http://in.business.yahoo.com/
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.

a "test.1.er" directory (experiment).
To view the experiment, run "analyzer" (Java GUI tool):
$ analyzer test.1.er
If everything works properly you will see MPI Timeline and other tabs,
that show profiling information. Please, make sure you have java 1.5 or
newer in your PA
how can i visualize the trace information i got vampir-trace.
Sorry for bugging everyone so much about this. But i spend a lot of time and
this alone and i am not getting output.

I have included screenshot (DIR=screenshots) of the profiler in the folder
attached with this email.
The application itself (source code or binary). BTW i am using ubuntu 8.04 32

Everything is included in the folder

HI Nik,
I tried the Sun Studio Performance Analyzer and it was able to profile

limit the email in the developers

2. Secondly if the developer could volunteer to become mentors for student
(particularly thesis student like m e :) ). I think they would benefit a lot.

Hi Everyone,
I wanted to ask some questions about things I am having trouble understanding.
1. As far as my understanding of MPI_INIT function, I assumed MPI_INIT
typically procedure resources required including the sockets. But now as I
understand from the documentation that open
ch is responsible for matching messages with posted receives. You
might need to look at the ompi/mca/pml/ob1 code to understand how that works.
Hope that gives you a starting point

Hi everyone,
I wanted to know how OpenMPI launches a MPI process in a cluster environment.
I am assuming if the process lifecycle management it will be using rsh.
Anyhelp would be greatly appreciated.
nd_Message by utilizing Open
MPI source code.
Also, I know i should be looking into PLM subsystem, RMAPS subsystem, ODLS
subsystem, and ORTED subsystem. But Ralph if you guide me a bit i can finish
the experiment with less sleepless night, headache, and stress.

Yes, you -could- hack the MPI code to do this. Starting from scratch, with
little knowledge of the code base - figure on taking awhile. I could probably
come up with a way to do it, but this would have to be a very low priority for
me.

I tested this on my machines and it worked, so hopefully it will meet your
needs. You only need to run one "ompi-server" period, so long as you locate it
where all of the processes can find the contact file and can open a TCP socket
to the daemon. There is a way to knit multiple ompi-servers int

Jeff, can you tell me the most simple way. It does not have to be perfect.
