Brief Description

Libckpt is a portable checkpointing tool for Unix. It provides a mechanism for enabling fault-tolerance for long-running programs. Libckpt implements most optimizations that have been proposed to improve the performance of checkpointing. Additionally, it implements ``user-directed'' checkpointing, a new optimization unique to Libckpt.

The Software

This software (actually the most recent revision called "clubs"), is available at: http://web.eecs.utk.edu/~jplank/plank/libckpt/clubs.shar.

If you try to use libckpt

Please drop me a line and let me know how it goes. I'd especially be interested in success stories -- i.e. if libckpt has benefitted your work. However, if you rejected libckpt for some reason, please let me know as well. Please send mail to plank@cs.utk.edu.
