I wrote some code with GASNet API (Global-Address Space Networking: http://gasnet.cs.berkeley.edu/)    and used MPI conduit for my gasnet application, so my program ran well with open-mpirun. Thus I thought that I could also use the transparent checkpoint/restart function supported by BLCR in Open-mpi. As opposed to my idea, it does not work and show the following error message.
--------------------------------------------------------------------------
Error: The process with PID 13896 is not checkpointable.
       This could be due to one of the following:
        - An application with this PID doesn't currently exist
        - The application with this PID isn't checkpointable
        - The application with this PID isn't an OPAL application.
       We were looking for the named files:
         /tmp/opal_cr_prog_write.13896
         /tmp/opal_cr_prog_read.13896
