KPart: A Hybrid Cache Partitioning-Sharing Technique for Commodity Multicores
Nosayba El-Sayed,Anurag Mukkara,Po-An Tsai,Harshad Kasture,Harshad Kasture,Xiaosong Ma,Daniel Sanchez +6 more
- 01 Feb 2018
TL;DR: KPart is presented, a hybrid cache partitioning-sharing technique that sidesteps the limitations of way-partitioning and unlocks significant performance on current systems, and achieves most of the performance of more advanced partitioning techniques that are not yet available in hardware.

TL;DR: Beacon, an end-to-end I/O resource monitoring and diagnosis system for the 40960-node Sunway TaihuLight supercomputer, has successfully helped center administrators identify obscure design or configuration flaws, system anomaly occurrences, I-O performance interference, and resource underor over-provisioning problems.
To checkpoint or not to checkpoint: Understanding energy-performance-I/O tradeoffs in HPC checkpointing
Nosayba El-Sayed,Bianca Schroeder +1 more
- 01 Sep 2014
TL;DR: In this article, the authors provide an extensive analysis of the energy/performance tradeoffs associated with an array of checkpoint scheduling policies, including policies that we propose, as well as few existing ones in the literature.
Checkpoint/restart in practice: When ‘simple is better’
Nosayba El-Sayed,Bianca Schroeder +1 more
- 01 Dec 2014
TL;DR: The goal is to identify methods for optimizing the checkpointing process that are easy to use in practice and at the same time achieve high quality solutions, and to evaluate an array of methods for optimize the checkpoint interval using real-world failure logs.
