Checkpointing and Migration of parallel processes based on Message Passing Interface

This paper presents a Checkpoint-based Rollback Recovery and Migration System for Message Passing Interface, ChaRM4MPI, for Linux Clusters. Some important fault tolerant mechanisms are designed and implemented in this system, which include coordinated checkpointing protocol, synchronized rollback recovery, process migration, and so on. Owing to ChaRM4MPI, the node transient faults can be recovered automatically, and the permanent fault can also be recovered through checkpoint mirroring and process migration techniques. Moreover, users can migrate MPI processes from one node to another manually for load balance or system maintenance. ChaRM4MPI is a user-transparent implementation and introduces a little running time overhead.
