Strong Scaling of OpenACC enabled Nek5000 on several GPU based HPC systems
Jonathan Vincent, Jing Gong, Martin Karp +11
We present new results on the strong parallel scaling for the OpenACC-accelerated implementation of the high-order spectral element fluid dynamics solver Nek5000. The test case con…
Multi-GPU Acceleration of the iPIC3D Implicit Particle-in-Cell Code
Chaitanya Prasad Sishtla, Steven W. D. Chien, Vyacheslav Olshevsky +2
iPIC3D is a widely used massively parallel Particle-in-Cell code for the simulation of space plasmas. However, its current implementation does not support execution on multiple GPU…
TensorFlow Doing HPC
Steven W. D. Chien, Stefano Markidis, Vyacheslav Olshevsky +3
TensorFlow is a popular emerging open-source programming framework supporting the execution of distributed applications on heterogeneous hardware. While TensorFlow has been initial…
Exploring the Vision Processing Unit as Co-processor for Inference
Sergio Rivas-Gomez, Antonio J. Peña, David Moloney +2
The success of the exascale supercomputer is largely debated to remain dependent on novel breakthroughs in technology that effectively reduce the power consumption and thermal diss…
Decoupled Strategy for Imbalanced Workloads in MapReduce Frameworks
Sergio Rivas-Gomez, Sai Narasimhamurthy, Keeran Brabazon +3
In this work, we consider the integration of MPI one-sided communication and non-blocking I/O in HPC-centric MapReduce frameworks. Using a decoupled strategy, we aim to overlap the…
MPI Windows on Storage for HPC Applications
Sergio Rivas-Gomez, Roberto Gioiosa, Ivy Bo Peng +4
Upcoming HPC clusters will feature hybrid memories and storage devices per compute node. In this work, we propose to use the MPI one-sided communication model and MPI windows as un…
