There is a typo in my previous posting. I have configured OpenMPI library with "-with-ft=cr".
Thanks Ananda From: Ananda Babu Mudar (WT01 - Energy and Utilities) Sent: Monday, August 23, 2010 11:50 AM To: 'de...@open-mpi.org' Subject: Question on MCA_BASE_METADATA_PARAM_NONE Hi In the file "mca_base_components_open.c", following code checks for the components that are checkpointable. If I configure OpenMPI library with "-enable-cr" option, I was under the assumption that all components will be checkpointable. However I see that quite a few components are not checkpointable and that list includes "Shared Memmory (sm)". Do I have to add any other options to "configure" command so that all components are checkpointable?
