Collectives in hybrid MPI+MPI code: design, practice and performance
Huan Zhou, Jose Gracia, Naweiluo Zhou +1
The use of hybrid scheme combining the message passing programming models for inter-node parallelism and the shared memory programming models for node-level parallelism is widely s…
MPI Collectives for Multi-core Clusters: Optimized Performance of the Hybrid MPI+MPI Parallel Codes
Huan Zhou, Jose Gracia, Ralf Schneider
The advent of multi-/many-core processors in clusters advocates hybrid parallel programming, which combines Message Passing Interface (MPI) for inter-node parallelism with a shared…
Guaranteeing Recoverability via Partially Constrained Transaction Logs
H. Zhou, J. W. Guo, H. Q. Hu +3
Transaction logging is an essential constituent to guarantee the atomicity and durability in online transaction processing (OLTP) systems. It always has a considerable impact on pe…
A Bandwidth-saving Optimization for MPI Broadcast Collective Operation
Huan Zhou, Vladimir Marjanovic, Christoph Niethammer +1
The efficiency and scalability of MPI collective operations, in particular the broadcast operation, plays an integral part in high performance computing applications. MPICH, as one…
Leveraging MPI-3 Shared-Memory Extensions for Efficient PGAS Runtime Systems
Huan Zhou, Kamran Idrees, José Gracia
The relaxed semantics and rich functionality of one-sided communication primitives of MPI-3 makes MPI an attractive candidate for the implementation of PGAS models. However, the pe…
DART-MPI: An MPI-based Implementation of a PGAS Runtime System
Huan Zhou, Yousri Mhedheb, Kamran Idrees +4
A Partitioned Global Address Space (PGAS) approach treats a distributed system as if the memory were shared on a global level. Given such a global view on memory, the user may prog…
