FusedOS: A Hybrid Approach to Exascale Operating Systems
SESSION: Research Poster Reception
EVENT TYPE: Posters and Electronic Posters
TIME: 5:15PM - 7:00PM
SESSION CHAIR: Torsten Hoefler
AUTHOR(S):Yoonho Park, Eric Van Hensbergen, Marius Hillenbrand, Todd Inglett, Bryan Rosenburg, Kyung Ryu, Robert Wisniewski
ROOM:East Entrance
ABSTRACT:
Historically, both Light-Weight and Full-Weight Kernel (LWK and FWK) approaches have been taken in providing an operating environment for high performance computing (HPC). The implications of these approaches impact the mechanisms providing resource management for heterogeneous cores on a single chip.
Rather than starting with an LWK or an FWK, we combined the two into an operating environment called FusedOS. In particular, we combine Linux and CNK environments on a single node by providing an infrastructure capable of partitioning resources of a manycore heterogeneous system.
Our contributions are three-fold. We present an architectural description of a novel manner for combining an FWK and LWK, retaining the best of each showing we can manage cores a traditional kernel can not. We describe a prototype environment running on current hardware. We present performance results demonstrating low noise, and show micro-benchmarks running with performance commensurate with CNK.
