Yeah, it was a bug in the parser - fix scheduled for 1.4.2 release.
Thanks!

Hello,
My question concerns the display of error message generated by a throw
std::runtime_error("Explicit error message").
I am launching on a terminal an openMPI program on several machines using:
mpirun -v -machinefile MyMachineFile.txt MyProgram.
I am wondering why I cannot see an error

Hello,
I have a general question about the best way to implement an openmpi
application, i.e the design of the application.
A machine (I call it the "server") should send to a cluster containing a lot
of processors (the "clients") regularly task to do (byte buffers from very
various size).

Hello,
I assume this question has been already discussed many times, but I can not
find on Internet a solution to my problem.
It is about buffer size limit of MPI_Send and MPI_Recv with heterogeneous
system (32 bit laptop / 64 bit cluster).
My configuration is :
open mpi 1.4, configured with:
Thank you Jeff for your explaination. It is much clearer now.
Best regards.

Hello,
My question is about virtual memory allocated by an open-mpi program. I am
not familiar with memory managment and I will be grateful if you could
explain me what I am observing when I launch my openMpi program on several
machines.
My program is started on a server machine which comunicate

My problem is still open... why is there a connection attempt to machine2

Has somebody an explanation ?

Hello,
I am using openmpi on several machines which have different user accounts
and I cannot find a way to specify the login for each machine in the
machinefile passed to mpirun.
The only solution I found is to use the -host argument of mpirun, such as:
mpirun -np 2 --host
