Userspace tools to Checkpoint and Restart Linux processes
BLCR (Berkeley Lab Checkpoint/Restart) allows programs running on Linux to be "checkpointed" (written entirely to a file), and then later "restarted". . BLCR can checkpoint both single- and multithreaded (pthreads) programs linked with the NPTL implementation of pthreads. BLCR is also able to save and restore groups of related processes together with the pipes that connect them. . This package contains utilities needed to launch and restart unmodified processes with checkpointing support.
