Hi! Berkely recently released a new version of their BLCR. They already marked the function cr_request_file as deprecated in BLCR 0.7.3. Now they removed deprecated functions from libcr API.
Since checkpointing support of OMPI is using cr_request_file, all checkpointing operations fail with BLCR 0.8.0b2, making a downgrade to BLCR 0.7.3 necessary. Best, Matthias
