Resilient workflows for high-performance simulation platforms

Workflows systems are considered here to support largescale multiphysics simulations. Because the use of large distributed and parallel multi-core infrastructures is prone to software and hardware failures, the paper addresses the need for error recovery procedures. A new mechanism based on asymmetric checkpointing is presented. A rule-based implementation for a distributed workflow platform is detailed.
