HARNESS and fault tolerant MPI
Initial versions of MPI were designed to work eciently on multi-processors which had very little job control and thus static process models. Subsequently forcing them to support a dynamic process model would have aected their performance. As current HPC systems increase in size with greater potential levels of individual node failure, the need arises for new fault tolerant systems to be devel...
متن کاملHARNESS fault tolerant MPI design, usage and performance issues
Initial versions of MPI were designed to work efficiently on multi-processors which had very little job control and thus static process models. Subsequently forcing them to support a dynamic process model suitable for use on clusters or distributed systems would have reduced their performance. As current HPC collaborative applications increase in size and distribution the potential levels of no...

متن کاملAutomatic Fault - Tolerant MPI
High performance computing platforms such as Clusters, Grid and Desktop Grids are becoming larger and subject to more frequent failures. MPI is one of the most used message passing libraries in HPC applications. These two trends raise the need for fault-tolerant MPI. The MPICH-V project focuses on designing, implementing and comparing several automatic fault-tolerant protocols for MPI applicati...
متن کاملBuilding and using an Fault Tolerant MPI implementation
In this paper we discuss the design and use of a fault tolerant MPI (FT-MPI) that handles process failures in a way beyond that of the original MPI static process model. FT-MPI allows the semantics and associated modes of failures to be explicitly controlled by an application via a modified functionality within the standard MPI 1.2 API. Given is an overview of the FT-MPI semantics, architecture...
