Hi,
I am a novice to openmpi. Just managed to get openmpi
running on my system.
I would like to modify the code for send and recv.
The target lower level device will be ethernet and
infiniband. I would like to know the files/functions
to look for. Could you please guide me in this.
thanks,

Hello,
I have written this short program

Hello!
A quick question.
Is anybody developing the OpenMPI bindings for Perl, Python and Java?
Thank you!

There are various projects out there that provide bindings in different
languages -- most (if not all?) simply layer on top of the native C
bindings, so you should be able to run them with Open MPI (disclaimer: I
have not tried any of these).
I know that I have seen MPI bindings for Java (there's

I don't think anyone is developing bindings for Open MPI's internal
functions for Perl, Python, or Java. However, if all you want is MPI

the predfined mpi op MPI_PROD is apparently wrong:

I've been using the oldish (2003) mpijava of late.
It holds up pretty well with modern mpis, but certain
jvms persist in causing extra copies, using SEGV as
a means of process control, etc.
If you don't need "true" sun java compatibility, you
can also use gcj (gcc suite) or titanium (berkeley)
