Compiler-assisted static checkpoint insertion
Junsheng Long, W.K. Fuchs, Jacob A. Abraham · 2003
The authors describe a compiler-assisted approach for static checkpoint insertion. Instead of fixing the checkpoint location before program execution, a compiler enhanced polling mechanism is utilized to maintain both the desired checkpoint intervals and reproducible checkpoint locations. The technique has been implemented in a GNU CC compiler for Sun 3 and Sun 4 (SPARC) processors. Experiments demonstrated that the approach provides for stable checkpoint intervals and reproducible checkpoint placements with performance overhead comparable to a previous compiler-assisted dynamic scheme.>
