. I am missing something? One side
question, I cannot find documentation for the mca parameter btl_tcp_frag.
I am currently using openmpi version 1.2.2.

Hi
Welcome to OpenMPI. Although I am yet to become an authority in the world of
openMPI, I will give you pointers to start.
I assume that you plan to submit the jobs without any scheduler (e.g
Maui/torque combination and stuff) and running the jobs simply by such a
command "mpirun -np 2 -host no
.
Xensockets initially were non-blocking send/recv, and did not have the
necessary code for supporting epoll/select. We had to add the necessary code
in the module so i am quite sure that they will work with the new opal/libevent.

happening. Basically, I am looking for a
place where tcp btl recv is getting called with all the goodies and parameters
which were passed by the MPI programmer. I hope I have made my question
understandable.

Thanks Seems, adding the callback magic is better option. Will bug u guys
in near future after some research on the issue.

I am back.. This time i am actually facing a problem. I should have send the
problem to eventlib mailing list first, but I thought your guys must be more
current with what I am doing, so i tried this list first.
I am trying to port xensockets to openmpi. In principle, I have the
pointed by you. I didnt
go into the detail, but i think I must have had corrupted the code somewhere.
The fresh tar, configure and make all install did the trick.

Where exactly are we increasing the size?

Dear Developers
I am planning to port tcp component to xensocket, which is a fast interdomain
communication mechanism for guest domains in Xen. I may add that Xensocket is
one way socket and I must admit before writing further that I am totally new to
OpenMPI or any other mpi implementation for
16 matches
