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
Gary,
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
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
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

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".

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
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)

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

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
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
