Intel MPI with pthread

I am trying to run a program that uses Pthread with Intel MPI. The program was compiled and linked successfully. I ran it on a dual-socket machine with two quad-core processors, but no threads seemed to be created. Below is the command I used:

mpirun -n 2 exectable

The program is supposed to generate 8 threads in one of the 2 processes. Thanks.

Error when linking with Intel MPI -- C++ Binding problem?

Hi,

I was trying to compile a c++ program using Intel compiler and Intel MPI 3.2. The compilation was successful, but during linking, I got the following error message:

: undefined reference to `MPI::INTEGER'

Is this a c++ binding problem, but isn't MPI 3.2 supposed to support C++ binding automatically? Could someone help me? Thanks!

MPI/IB Jobstart hanging

Hello to All,

I'm trying to start an MPI Job with a setup
SLES10SP2, IntelMPI3.0.1, OFED 1.2.5.4

When I try to run a Job with these env's:

export I_MPI_DEVICE=rdssm:OpenIB-cma
export I_MPI_DEBUG=256

My Job trys to start, but then hangs setting up the communication (see below).

dapltest works on the other hand.

inodeXYZ is the IPoIB adress of a node

Whats wrong?

Problem with Using Counters (ITAC)

Hi!

I'm using the following code to log the variable momentum whenever its value changes at runtime:

.
.
.
VT_classdef( "Counters", &counter_class);

MPI: Prevent mpirun from terminating on SIGTERM

Hi,

I'm using a IntelMPI with PBS.
When I send a SIGTERM signal using qdel to my job mpirun exits immediatly and my program that is called by mpirun has no time to finish its cleanup work.
(I'm using
if [ x$PBS_ENVIRONMENT != x ]; then
trap "" SIGTERM
fi
in my ~/.profile to prevent any shell from exiting when it gets the SIGTERM)

How can I tell IntelMPI's mpirun not to exit on SIGTERM?

Cheers,
Manuel
