Exploring and Analyzing the Real Impact of Modern On-Package Memory on HPC Scientific Kernels
Li, Ang; Liu, Weifeng; Kristensen, Mads R. B.; Vinter, Brian; Wang, Hao; Hou, Kaixi; Marquez, Andres; Song, Shuaiwen Leon (Journal article; Peer reviewed, 2017)High-bandwidth On-Package Memory (OPM) innovates the conventional memory hierarchy by augmenting a new on-package layer between classic on-chip cache and off-chip DRAM. Due to its relative location and capacity, OPM is ... -
Fast synchronization-free algorithms for parallel sparse triangular solves with multiple right-hand sides
Liu, Weifeng; Li, Ang; Hogg, Jonathan D; Duff, Iain S; Vinter, Brian (Journal article, 2017)The sparse triangular solve kernels, SpTRSV and SpTRSM, are important building blocks for a number of numerical linear algebra routines. Parallelizing SpTRSV and SpTRSM on today's manycore platforms, such as GPUs, is not ...
