Open MPI (trunk/1.7 - not 1.4 or 1.5) provides an application level interface to request a checkpoint of an application. This API is defined on the following website: http://osl.iu.edu/research/ft/ompi-cr/api.php#api-cr_checkpoint
This will behave the same as if you requested the checkpoint of the job from the command line. -- Josh On Mon, Oct 24, 2011 at 12:37 PM, Nguyen Toan <nguyentoan1...@gmail.com> wrote: > Dear all, > I want to automatically checkpoint an MPI program with OpenMPI ( I'm > currently using 1.4.2 version with BLCR 0.8.2), > not by manually typing ompi-checkpoint command line from another terminal. > So I would like to know if there is a way to call checkpoint function from > inside an MPI program > with OpenMPI or how to do that. > Any ideas are very appreciated. > Regards, > Nguyen Toan > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users > -- Joshua Hursey Postdoctoral Research Associate Oak Ridge National Laboratory http://users.nccs.gov/~jjhursey
