Performance Evaluation of Advanced Features in CUDA Unified Memory
Steven W. D. Chien, Ivy B. Peng, Stefano Markidis
CUDA Unified Memory improves the GPU programmability and also enables GPU memory oversubscription. Recently, two advanced memory features, memory advises and asynchronous prefetch,…
Posit NPB: Assessing the Precision Improvement in HPC Scientific Applications
Steven W. D. Chien, Ivy B. Peng, Stefano Markidis
Floating-point operations can significantly impact the accuracy and performance of scientific applications on large-scale parallel systems. Recently, an emerging floating-point for…
Studying dawn-dusk asymmetries of Mercury's magnetotail using MHD-EPIC simulations
Yuxi Chen, Gabor Toth, Xianzhe Jia +5
MESSENGER has observed a lot of dawn-dusk asymmetries in Mercury's magnetotail, such as the asymmetries of the cross-tail current sheet thickness and the occurrence of flux ropes,…
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…
Particle-in-Cell Simulations of Plasma Dynamics in Cometary Environment
Chaitanya Prasad Sishtla, Vyacheslav Olshevsky, Steven W. D. Chien +2
We perform and analyze global Particle-in-Cell (PIC) simulations of the interaction between solar wind and an outgassing comet with the goal of studying the plasma kinetic dynamics…
