Boosting Earth System Model Outputs And Saving PetaBytes in their Storage Using Exascale Climate Emulators
Sameh Abdulah, Allison H. Baker, George Bosilca +9
We present the design and scalable implementation of an exascale climate emulator for addressing the escalating computational and storage requirements of high-resolution Earth Syst…
Cache Optimization and Performance Modeling of Batched, Small, and Rectangular Matrix Multiplication on Intel, AMD, and Fujitsu Processors
Sameer Deshmukh, Rio Yokota, George Bosilca
Factorization and multiplication of dense matrices and tensors are critical, yet extremely expensive pieces of the scientific toolbox. Careful use of low rank approximation can dra…
distributed direct factorization of structured dense matrices using runtime systems
Sameer Deshmukh, Qinxiang Ma, Rio Yokota +1
Structured dense matrices result from boundary integral problems in electrostatics and geostatistics, and also Schur complements in sparse preconditioners such as multi-frontal met…
Implicit Actions and Non-blocking Failure Recovery with MPI
Aurelien Bouteiller, George Bosilca
Scientific applications have long embraced the MPI as the environment of choice to execute on large distributed systems. The User-Level Failure Mitigation (ULFM) specification exte…
Callback-based Completion Notification using MPI Continuations
Joseph Schuchart, Philipp Samfass, Christoph Niethammer +2
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…
Quo Vadis MPI RMA? Towards a More Efficient Use of MPI One-Sided Communication
Joseph Schuchart, Christoph Niethammer, José Gracia +1
The MPI standard has long included one-sided communication abstractions through the MPI Remote Memory Access (RMA) interface. Unfortunately, the MPI RMA chapter in the 4.0 version…
