Pickle: Precise, Flexible Cross-Core Last-level Cache Data Prefetching for Irregular Memory Accesses
Hoa Nguyen, Pongstorn Maidee, Jason Lowe-Power +1
Graph analytics and sparse scientific workloads are dominated by parallel chains of data-dependent, long-latency memory accesses whose patterns are difficult for hardware to infer…
Choreographer: A Full-System Framework for Fine-Grained Tasks in Cache Hierarchies
Hoa Nguyen, Pongstorn Maidee, Jason Lowe-Power +1
In this paper, we introduce Choreographer, a simulation framework that enables a holistic system-level evaluation of fine-grained accelerators designed for latency-sensitive tasks.…
Portable Targeted Sampling Framework Using LLVM
Zhantong Qiu, Mahyar Samani, Jason Lowe-Power
Evaluating architectural ideas on realistic workloads is increasingly challenging due to the prohibitive cost of detailed simulation and the lack of portable sampling tools. Existi…
Characterizing GPU Energy Usage in Exascale-Ready Portable Science Applications
William F. Godoy, Oscar Hernandez, Paul R. C. Kent +8
We characterize the GPU energy usage of two widely adopted exascale-ready applications representing two classes of particle and mesh solvers: (i) QMCPACK, a quantum Monte Carlo pac…
