Hi everyone,
I have installed openmpi-1.2.3. My system has two ethernet ports. Thus, I am
trying to make use of both ports to speed up the communication process by using
openmp to split into two threads. However, this implementation always cause
error. Then I realized that I need to build openm
Hi Josh,
I believe the problem is that you are only applying the MCA

Thank you *very* much.. applying the parameters with -gmca works fine with
the test case (and I'll try the actual one soon). However and this is
minor since it w
I believe the problem is that you are only applying the MCA
parameters to the first app context instead of all of them:

Attached is the config.log file for intel 9.1.052. I've also tried the
intel 10.1.008 and posted to this list the config.log on a previous
e-mail (12/2/2007).
Here are the key commands for building and installing
export FC=ifort
export F77=ifort
export CXX=icpc
export CC=icc
./configure --p
If you're seeing the same error from 2 entirely different MPI
implementations, it is possible that it is an error in your code.
Ensure that all processes are calling MPI_Bcast with the same
arguments (e.g., count, datatype, root, etc.), even on that 4000th
iteration.
How big are the block
Dear Friends,
I am writing a matrix multiplication program with MPI. MPI_Bcast does
not broadcast to all processes, in last iteration for block size
greater than a specific size. I test it with both MPICH and OPENMPI.I
have 12 processes which 7 of them are reached to MPI_Bcast but when
master (ran
As a quick follow-up to my own post, I just tried this on a few other
systems:
1) One system, on which the nodes have only one ethernet device, running the
code with the split "-np" arguments works fine.
2) Another system, which has IB links (as default), runs the code fine.
3) Two very similar
Hi guys,
I seem to have encountered an error while trying to run an MPMD executable
through Open MPI's '-app' option, and I'm wondering if anyone else has seen
this or can verify this?
Backing up to a simple example, running a "hello world" executable (hwc.exe)
works fine when run as: (using a
