Hi;
I'm trying to use BLCR to checkpoint OpenMPI applications
but I'm having lots of problems. To begin, I'm note sure that
openmpi recognizes blcr. I compiled open mpi with the
--with options like I used to do with lam versions.
The ompi_info doesn't seems to show blcr support.
Any hints? Som
Hi,
I have always used MPICH for my MPI projects, but changed to open-mpi
for its better integration with eclipse.
First of all, I got an error when using gcc 4.x when compiling the code,
but I think this was discussed earlier on the mailinglist.
I downgraded gcc and have succesfully compil

Alex,
Checkpoint/Restart is not supported in Open MPI, at the moment. The
integration of LAM/MPI style of process fault tolerance using a
single process checkpointer (e.g. BLCR) is currently under active
development. Unfortunately, I cannot say exactly when you will see it
released, but k

Thanks a lot!!

I looked at your docummentations but was not sure if it was

It works with lam-mpi, so probably still something wrong with open-mpi ?

There are 2 things that have to be done in order to be able to run a
Open MPI application. First the runtime environment need access to
some of the files in the bin directory so you have to add the Open
MPI bin directory to your path. And second, as we use shared
libraries the OS need to kn

Hello,
I seem to have encountered a bug in Open MPI 1.0 using indexed datatypes
with MPI_Recv (which seems to be of the "off by one" sort). I have
joined a test case, which is briefly explained below (as well as in the
source file). This case should run on two processes. I observed the bug

Yvan,
I'm looking into this one. So far I cannot reproduce it with the
current version from the trunk. I will look into the stable versions.
Until I figure out what's wrong, can you please use the nightly
builds to run your test. Once the problem get fixed it will be
included in the 1.0.2

The all2all scheduling works only because we know they will all send
the same amount of data, so the communications will take "nearly" the
same time. Therefore, we can predict how to schedule the
communications to get the best out of the network. But this approach
can lead to
