FAILURE RECOVERY FOR TRANSPLANTING ALGORITHMS FROM CLUSTER TO CLOUD

摘要

A method (400) of providing failure recovery capabilities to a cloud environment (10) for scientific HPC applications. An HPC application with MPI implementation extends the class of MPI programs to embed the HPC application with various degrees of fault tolerance. An MPI fault tolerance mechanism realizes a recover-and-continue solution. If an error occurs, only failed processes re-spawn, the remaining living processes remain in their original processors/nodes (12, 14, 16), and system recovery costs are thus minimized.
