%description
Berkeley Lab Checkpoint/Restart (BLCR) for Linux is a project of
Future Technologies Group researchers to develop a hybrid kernel/user
implementation of checkpoint/restart. Their goal is to provide a
robust, production quality implementation that checkpoints a wide
range of applications, without requiring changes to be made to
application code. This work focuses on checkpointing parallel
applications that communicate through MPI, and on compatibility with
the software suite produced by the SciDAC Scalable Systems Software
ISIC.

Berkeley Lab Checkpoint/Restart (BLCR) dla Linuksa to projekt badaczy
Future Technologies Group polegający na stworzeniu hybrydowej
(działającej w jądrze i przestrzeni użytkownika) implementacji
mechanizmu checkpoint/restart (punktów kontrolnych i restartów
programów). Celem jest dostarczenie bogatej, mającej produkcyjną
jakość implementacji potrafiącej wykonać migawki stanu szerokiej gamy
aplikacji bez potrzeby wykonywania zmian w ich kodzie. Praca skupia
się na aplikacjach równoległych komunikujących się poprzez MPI oraz
zgodności z oprogramowaniem tworzonym przez SciDAC Scalable Systems
Software ISIC.
