Dear all,
Could anyone please clarify me the difference between MPI_Bsend and
MPI_Ibsend? Or, in other words, what exactly is "blocking" in
MPI_Bsend, when the data is stored in the buffer and we "return"? :-)
Another, but similar, question:
What about the data-buffer - when can it be reused in

Hello everyone!
I am trying to run 11 instances of my program on 6 dual-core Opterons
(it is not time-consuming application anyway, takes 10 seconds at
one-core laptop :)).
so, when I type:
mpiexec -machinefile hostfile -n 11 ./program
nothing happens!
The output of:

can't find what can be a problem anywhere in the literature, so
I would really appreciate if anyone of you could check out the code
below quickly and maybe give me some advice, or tell me what's wrong
with it.
Thanks a lot in advance.

Hello,
I'm new to MPI, so I'm going to explain my problem in detail
I'm trying to compile a simple application using mpicc (on SUSE 10.0)
and run it - compilation passes well, but mpirun is the problem.
So, let's say the program is called 1.c, I tried the following:
mpicc -o 1 1.c
(and, just
