Hi,
OpenMPI-1.7.1 is announce support MPI-3 functionality such as non-blocking
collectives.
I have test MPI_Iallgatherv on a 8-node cluster, however, I got bad
performance. The MPI_Iallgatherv block the program for even longer time
than traditional MPI_Allgatherv.
Following is the test pseudo-co
Hello Following problem is solved by recompiling and reinstall Open MPI
for each nodes.
Thank you for your coorpolation.

I have no idea how MacPorts configures OMPI - did you check the output of
ompi_info to see if threading was even enabled?

Hi!
I use OpenMPI 1.7.1 from MacPorts (+threads +gcc47). When compiling a simple
hello world program calling
MPI_Init_thread(&argc, &argv, MPI_THREAD_SERIALIZED, &provided);
the program hangs if run on more than one process. All works fine if I
- either use MPI_THREAD_SINGLE
- or use OpenMPI
I'd like to bump this question. I also wanted to ask: I've been
searching the archives, and it seems that in past versions of OMPI,
only MPI_THREAD_SINGLE was available from the default configuration of
OMPI. It seems that as long as calls to MPI were serialized, however,
there were no issues.
Thanks.
That's exactly the problem. When add prefix to the mpirun command,
everything goes fine.

Check the PATH you get when you run non-interactively on the remote machine:
ssh gnode100 env | grep PATH

I think the PATH setting is ok. I forgot to mention that it run well on
local machine.
The PATH setting on the local machine is
[cmy@gLoginNode1 ~]$ echo $PATH
/home/cmy/clc/benchmarks/nasm-2.09.10:*/home3/cmy/czh/opt/ompi-1.7.1/bin/*
:/home3/cmy/czh/opt/autoconf-2.69/bin/:/home3/cmy/czh/opt/mvap
Gus picked up the issue properly - you're setting CXX to gcc; it needs to be
g++.
If configure fails with g++, then you have a busted C++ compiler (that's a
guess; I haven't seen the output from failed configure when uu specify
CXX=g++). You can disable OMPI's use of C++ with. --disable-MPI-CXX
You aren't setting the path correctly on your backend machines, and so they are
picking up an older version of OMPI.

Hi all,
Jeff -- I am not sure want do you mean by STL but currently I am using
mpich-3.0.4 with gcc and I don't have any problem. Is there a way to know
if C++ still works on Mac or not? I am sure that on Mac I use C++ but i
haven't try to use it before.
