Lazy Fault Detection for Redundant MPI
… algorithms to lazily detect faults in replicated MPI applications, allowing for more flexibility in replica scheduling and potential power savings. Evaluation shows that, when all processes are operated at full power, this approach allows applications to complete substantially faster as compared …

Multi-level Parallelism with MPI and OpenACC for CFD Applications
High-level parallel programming approaches, such as OpenACC, have recently become popular in complex fluid dynamics research since they are cross-platform and easy to implement. OpenACC is a directive-based programming model that, unlike low-level programming models, abstracts the details of …

MPIOR: A Framework to Analyze File System Performance of MPI Applications
MPI I/O replay (MPIOR) is an I/O performance modeling and prediction tool used to trace and replay a parallel application to determine application performance under a new I/O sub system. The trace collector deduces synchronization inter-dependencies between nodes and I/O demands placed by each node …
