Bonjour,
I'm not sure I understand how to trigger CHECKSUM use
inside of OpenMPI 1.4.1 (after digging in the FAQs, I got not explanations,
sorry):
- Is checksuming activated by default and embedded automatically
within the Send/Recv pair mechanism, please ?
- If not, which MCA param(S) should I
Have you tried testing without using the NFS? So setting the mca-params.conf to
something like:
crs_base_snapshot_dir=/tmp/
snapc_base_global_snapshot_dir=/tmp/global
snapc_basee_store_in_place=0
This would remove the NFS time from the checkpoint time. However if you are
using staging this may o
Hi,
Thanks Nysal for these details.
I also fixed my memory allocation issue using environment variable
OMPI_MCA_memory_ptmalloc2_disable which is much more easier (at least in my
case) than compiled new openmpi package and install that new package.
The point is that it is a bit complicated to hav
Dear Colleagues,
this is a short survey (21 questions that take about 10 minutes to
answer) in context of the research work for my PhD thesis and the Munich
Center of Advanced Computing (Project B2). It would be very helpful, if
you will take the time to answer my questions concerning the use
Hi, I wanted to use openmpi, I install with no errors, and when I run de
examples in local it work well, but when I specify another host to run it
doesn't work. There are no errors but the it doesn't show anything and don't
start the process in another host and don't stop to run in localhost. Then
Check firewall, network setting like subnet, and ssh keys?

These FAQ may help:

Also, make sure the same OpenMPI is either installed on,
or accessible by (say via NFS) the "anotherhost".
Simple test: 'mpirun -np 8 --host [localhost,anotherhost] hostname'

Hi all,
I'm have a C MPI code that I need to link into my C++ code. As usual,
from my C++ code, I do
extern "C" {
#include "c-code.h"
}
where c-code.h includes, among other things, mpi.h.
This doesn't work, because it appears mpi.h tries to detect whether
it's being compiled as C or C++ and inc
Dear opem-mpi users:
I have got the following error while compiling openmpi using pgf90 ver 9
