Abstract	This talk addresses issues of fault tolerance in large-scale supercomputing clusters. In particular, we discuss ways that compiler technology can transparently support efficient checkpointing of MPI programs. Our main goal is to strategically place checkpoints to reduce bandwidth contention among processes and to reduce checkpoint size within each process. In contrast to other proposed techniques, our solution ensures no extra messages or useless checkpoints, allowing for low failure-free overhead. This talk discusses both our on-going efforts and future plans.
