Thanks for your replies.
I use Snow Leopard, running ompi_info returns an error (command not found).
I was looking for installers and I remember that I have installed MPICH2 if I
recall correctly (I didn't knew about openMPI until today), so I have mpicc
installed.
Should I remove MPICH2 and i

I'm on this version too. Which version of Xcode do you use - "Xcode 3.2.6 and
iOS SDK 4.3"? Attached is a small file which I can compile with t

Offhand, your code looks fine.
Can you send a small, self-contained example?

Who's going to Salt Lake City for SC12 next week?
I am! Come find me at the Cisco booth.
I'll be talking about some ultra-low latency Ethernet stuff Cisco will be
pushing upstream to Open MPI, and any other general MPI/HPC/Notre Dame football
stuff that you'd like to discuss. Oh, and probab
Answering my own question, I have downloaded openMPI 1.6.2 and still get the
delay in the MPI_Send. Previously, I was using openMPI 1.4.1
I configured 1.6.2 with -enable-peruse and have implemented PERUSE callbacks.
Here is a trace of gb2 (PROC39) sending messages to ob (PROC28)
PROC39: 59.2268
I just built OpenMPI 1.6.3 with ifort 12.1.4. When running ifort I am
getting the warning:
ifort: command line remark #10010: open '-pthread' is depreciated and
will be removed in a future release. See '-help deprecated'.
Is -pthread really needed? Is there a configure option to change this
or
Try configuring --without-threads

We're actually getting this flag from Libtool during configure. :-\
Hopefully they're updating Libtool upstream to account for this.
If Ralph's suggestion doesn't work, you can always edit the wrapper compiler
data files to remove -pthread after you "make install".

Talked to one of our developers (afraid everyone is swamped with SC12 right
now), and we have a few suggestions:
1. to reduce OS-jitter, have you tried --bind-to-core or --bind-to-socket? This
would avoid context switches throwing you onto different memory segments
2. we recall you had an issue
I set processor affinity by running a script after all processes are running.
My processes are bound to their own core. Each process has 3 threads, one is
my app and the other 2 appear after MPI_Init is called.
Each thread in a process is bound to the same core and the processes are
running with

Looking at the trace it become clear that the culprit is the receiving process
and not the sending one.
Let me walk you over. I split the trace in several groups. The first one will
look at the sender (proc39) and the receiver (proc28) for the first message.
PROC39: 59.2268409810; SEND_R
Thanks Reuti for the sample.
I have the latest Xcode available on the Apple dev center; Xcode 4 probably?
I think that the reason why nothing happens is because the code runs via
MPICH2; tried to launch mpicc with the -echo flag and i see in the output
-I/opt/local/include/mpich2 -L/opt/local/l
