Fibers are not (P)Threads: The Case for Loose Coupling of Asynchronous Programming Models and MPI Through Continuations
Joseph Schuchart, Christoph Niethammer, José Gracia
Asynchronous programming models (APM) are gaining more and more traction, allowing applications to expose the available concurrency to a runtime system tasked with coordinating the…
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…
Performance and energy consumption of HPC workloads on a cluster based on Arm ThunderX2 CPU
Filippo Mantovani, Marta Garcia-Gasulla, José Gracia +5
In this paper, we analyze the performance and energy consumption of an Arm-based high-performance computing (HPC) system developed within the European project Mont-Blanc 3. This sy…
