As high-performance clusters continue to grow in size and popularity, issues of fault tolerance and reliability are becoming limiting factors on application scalability. To address these issues, we present the design and implementation of a system for providing coordinated checkpointing and rollback recovery for MPI-based parallel applications. Our approach integrates the Berkeley Lab BLCR kernellevel process checkpoint system with the LAM implementation of MPI through a defined

Experimental results show negligible communication performance impact due to the incorporation of the checkpoint support capabilities into LAM/MPI.
