Dear Josh,
Thank you. I will test the 1.7 trunk as you suggested.
Also I want to ask if we can add this interface to OpenMPI 1.4.2,
because my applications are mainly involved in this version.

Any ideas are very appreciated.

Hi Roman,
Did you try to checkpoint and restart with the parameter "-machinefile". It
may work.

Thanks Josh.
Actually I also tested with the Himeno
benchmark<http://accc.riken.jp/assets/files/himenob_loadmodule/himenoBMT_c_mpi.lzh>and
got the same problem, so I think this could be a bug.
Hope this information also helps.

Dear Josh,
Did you find out the problem? I still cannot progress anything.
Hope to hear some good news from you.

Hi Josh,
I tried the MCA parameter you mentioned but it did not help, the unknown
overhead still exists.
Here I attach the output of 'ompi_info', both version 1.5 and 1.5.1.
Hope you can find out the problem.
Thank you.

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

Dear all,
I am having a problem while running mpirun in OpenMPI 1.5 version. I
compiled OpenMPI 1.5 with BLCR 0.8.2 and OFED 1.4.1 as follows:
./configure \
--with-ft=cr \
--enable-mpi-threads \
--with-blcr=/home/nguyen/opt/blcr \
--with-blcr-libdir=/home/nguyen/opt/blcr/lib \
Dear Josh,
I hope to see this new API soon. Anyway, I will try these critical section
functions in BLCR. Thank you for the support.

to the overall checkpoint overhead in
Open MPI. Is it because of the increase of coordination time for checkpoint?
And what is included in the overall checkpoint overhead besides the BLCR's
checkpoint overhead and coordination time?
Thank you.

int time (executing ompi-checkpoint), is there a way to let
OpenMPI wait until my_atomic_func() finishes its operation?
+ How does ompi-checkpoint operate to checkpoint MPI threads?

Hi all,
I finally figured out the answer. I just put the parameter "-machinefile
host" in the "ompi-restart" command and it restarted correctly. So is it
unable to restart multi-threaded application on 1 node in OpenMPI?
