Hi all,
I am using the latest version of OpenMPI (1.5.1) and BLCR (0.8.2).
I found that when running an application,which uses MPI_Isend, MPI_Irecv and
MPI_Wait,
enabling C/R, i.e using "-am ft-enable-cr", the application runtime is much
longer than the normal execution with mpirun (no checkpoint
Hi Michael,
You may have tried to send some debug information to the list, but it
appears to have been blocked. Compressed text output of the backtrace
text is sufficient.
Thanks,

There are a few reasons why this might be occurring. Did you build with the
'--enable-ft-thread' option?
If so, it looks like I didn't move over the thread_sleep_wait adjustment from
the trunk - the thread was being a bit too aggressive. Try adding the following
to your command line options, an

Odd, I thought I sent it to you directly. In any case,

I would personally suggest not reconfiguring your system simply to support a
particular version of OMPI. The only difference between the 1.4 and 1.5 series
wrt slurm is that we changed a few things to support a more recent version of
slurm. It is relatively easy to backport that code to the 1.4
