Hello,
I'm a senior year Computer Science student working on Parallel Clustering
Algorithms at BITS Pilani, India. I have a few questions about using mpicc
and mpicxx with multiple versions of gcc / g++.
I am using Ubuntu 12.04 equipped with gcc 4.6.4. The currently installed
mpicc is bound to gc

Can you try setting the environment variable OMPI_CXX=
Then run:
mpicxx -v
and see what version it says its running. You may have to be careful mixing the
versions too far apart.

Dear colleagues,
I have a parallel MPI application written in C that works normally in
a serial version and in the parallel version in the sense that all
numerical output is correct. When it tries to shut down, it gives the
following console error messsage:
Primary job terminated normally, but 1
t; 2) error in MPI_Send() shown below on local machine with

Hi folks,
I've been running into some issues using the MPI_IN_PLACE option with
MPI_Ireduce, in what seems to be a regression from OpenMPI v1.10.1. In
particular, I encounter data corruption if non-root ranks supply the same
pointers for 'send' and 'recv', even though this should have no bearin
Andre,
this issue has already been reported and fixed
(the fix will be available in v2.0.2)
Meanwhile, you can manually apply the fix available at
