MPI Streams for HPC Applications
Ivy Bo Peng, Stefano Markidis, Roberto Gioiosa +2
Data streams are a sequence of data flowing between source and destination processes. Streaming is widely used for signal, image and video processing for its efficiency in pipelini…
Preparing HPC Applications for the Exascale Era: A Decoupling Strategy
Ivy Bo Peng, Roberto Gioiosa, Gokcen Kestor +2
Production-quality parallel applications are often a mixture of diverse operations, such as computation- and communication-intensive, regular and irregular, tightly coupled and loo…
Extending Message Passing Interface Windows to Storage
Sergio Rivas-Gomez, Stefano Markidis, Ivy Bo Peng +3
This work presents an extension to MPI supporting the one-sided communication model and window allocations in storage. Our design transparently integrates with the current MPI impl…
Exploring the Performance Benefit of Hybrid Memory System on HPC Environments
Ivy Bo Peng, Roberto Gioiosa, Gokcen Kestor +2
Hardware accelerators have become a de-facto standard to achieve high performance on current supercomputers and there are indications that this trend will increase in the future. M…
Idle Period Propagation in Message-Passing Applications
Ivy Bo Peng, Stefano Markidis, Erwin Laure +2
Idle periods on different processes of Message Passing applications are unavoidable. While the origin of idle periods on a single process is well understood as the effect of system…
Exploring Application Performance on Emerging Hybrid-Memory Supercomputers
Ivy Bo Peng, Stefano Markidis, Erwin Laure +2
Next-generation supercomputers will feature more hierarchical and heterogeneous memory systems with different memory technologies working side-by-side. A critical question is wheth…
Global three-dimensional simulation of Earth's dayside reconnection using a two-way coupled magnetohydrodynamics with embedded particle-in-cell model: initial results
Yuxi Chen, Gabor Toth, Paul Cassak +6
We perform a three-dimensional (3D) global simulation of Earth's magnetosphere with kinetic reconnection physics to study the flux transfer events (FTEs) and dayside magnetic recon…
