Parallel I/O Performance for Application–Level Checkpointing on the Blue Gene/P
- System, Workshop on Interfaces and Architectures for Scientific Data Storage (IASDS), in conjunction with IEEE International Conference on Cluster Computing (Cluster), 26–30
, 2011
"... Abstract—As the number of processors increases to hundreds of thousands in parallel computer architectures, the failure probability rises correspondingly, making fault tolerance a highly important and challenging task. Application-level checkpointing is one of the most popular techniques to proactiv ..."

massively parallel system. In this paper, we examine application-level checkpointing for a massively parallel electromagnetic solver system called NekCEM on the IBM Blue Gene/P at Argonne National Laboratory. We discuss an application-level, two-phase I/O approach, called “reduced-blocking I/O ” (rb
Dynamic malleability in mpi applications
- In Seventh IEEE International Symposium on Cluster Computing and the Grid (CCGrid 2007
, 2007
"... Malleability enables a parallel application’s execution system to split or merge processes modifying the parallel application’s granularity. While process migration is widely used to adapt applications to dynamic execution environments, it is limited by the granularity of the application’s processes ..."

A Middleware Framework for Dynamically Reconfigurable MPI Applications
"... Computational grids are characterized by their dynamic, non-dedicated, and heterogeneous nature. Novel application-level and middleware-level techniques are needed to allow applications to reconfigure themselves and adapt automatically to their underlying execution environments to be able to benefit ..."

In this paper, we introduce a new software framework that enhances the Message Passing Interface (MPI) performance through process checkpointing, migration, and an adaptive middleware for load balancing. Fields as diverse as fluid dynamics, material science
DMTCP: Transparent Checkpointing for Cluster Computations and the Desktop
"... DMTCP (Distributed MultiThreaded CheckPointing) is a transparent user-level checkpointing package for distributed applications. Checkpointing and restart is demonstrated for a wide range of over 20 well known applications, including MATLAB, Python, TightVNC, MPICH2, OpenMPI, and runCMS. RunCMS runs ..."

Improving MPI Independent Write Performance Using A Two-Stage Write-Behind Buffering Method
"... Many large-scale production applications often have very long executions times and require periodic data checkpoints in order to save the state of the computation for program restart and/or tracing application progress. These write-only operations often dominate the overall application runtime, whic ..."

Existing approaches for write-behind data buffering at the MPI I/O level have been proposed, but challenges still exist for addressing system-level I/O issues. We propose a twostage write-behind buffering scheme for handing checkpoint operations. The first
Proactive Process-Level Live Migration and Back Migration in HPC Environments
"... As the number of nodes in high-performance computing environments keeps increasing, faults are becoming common place. Reactive fault tolerance (FT) often does not scale due to massive I/O requirements and relies on manual job resubmission. This work complements reactive with proactive FT at the proc ..."

A novel process-level live migration mechanism supports continued execution of applications during much of processes migration. This scheme is integrated into an MPI execution environment
User-Level Socket-Based Checkpointing for Distributed and Parallel Computation
, 2009
"... We present a preliminary description of a user-level checkpointing package, DMTCP, for Linux. The socket-based approach presents a novel method for checkpointing distributed processes. This includes checkpointing of any dynamically created POSIX threads and forked child processes. It also includes c ..."

The package also checkpoints signal handlers, ordinary file descriptors, socket descriptors, and certain other types
DMTCP: Scalable User-Level Transparent Checkpointing for Cluster Computations
