Abstract

Linux-based operating systems and runtimes (OS/Rs) have emerged as the environments of choice for the majority of HPC systems. While Linux-based OS/Rs have advantages such as extensive feature sets and developer familiarity, these features come at the cost of additional system overhead. In contrast to Linux, there is a substantial history of work in the HPC community focused on lightweight OS/Rs that provide scalable and consistent performance for HPC applications, but lack many of the features offered by commodity OS/Rs. In this paper, we propose to bridge the gap between LWKs and commodity OS/Rs by selectively providing a lightweight memory subsystem for HPC applications in a commodity OS/R where concurrently executing a diverse range of workloads is commonplace. Our system HPMMAP provides lightweight memory performance transparently to HPC applications by bypassing Linux's …
