Hi Josh/all, I have upgraded the openmpi to v 1.4 but still get the same error when I try executing the application on multiple nodes:
******************* Error: expected_component: PID information unavailable! Error: expected_component: Component Name information unavailable! ******************* I am running my application from the node 'portal11' as follows: mpirun -am ft-enable-cr -np 2 --hostfile hosts myapp. The file 'hosts' contains two host names: portal10, portal11. I am triggering the checkpoint using ompi-checkpoint -v 'PID' from portal11. I configured open mpi as follows: ##################### ./configure --prefix=/home/jean/openmpi/ --enable-picky --enable-debug --enable-mpi-profile --enable-mpi-cxx --enable-pretty-print-stacktrace --enable-binaries --enable-trace --enable-static=yes --enable-debug --with-devel-headers=1 --with-mpi-param-check=always --with-ft=cr --enable-ft-thread --with-blcr=/usr/local/blcr/ --with-blcr-libdir=/usr/local/blcr/lib --enable-mpi-threads=yes ######################### Question: what do you think can be wrong? Please instruct me on how to resolve this problem.

If so, can you provide me with some information on how to > achieve this. Open MPI is able to checkpoint a multi-node application (that's what it was designed to do).
