SUMMARY:TOSS-2020: A Commodity Software Stack for HPC
DESCRIPTION:Paper\n\nTOSS-2020: A Commodity Software Stack for HPC\n\nLeon
 , D'Hooge, Hanford, Karlin, Pankajakshan...\n\nThe simulation environment 
 of any HPC platform is key to the performance, portability and productivit
 y of scientific applications. This environment has traditionally been prov
 ided by platform vendors, presenting challenges for HPC centers and users;
  including platform-specific software that tends to stagnate over the life
 time of the system. In this paper, we present the Tri-Laboratory Operating
  System Stack (TOSS), a production simulation environment based on Linux a
 nd open source software, with proprietary software components integrated a
 s needed. TOSS, focused on mid-to-large scale commodity HPC systems, provi
 des a common simulation environment across system architectures, reduces t
 he learning curve on new systems and benefits from a lineage of past exper
 ience and bug fixes. To further the scope and applicability of TOSS, we de
 monstrate its feasibility and effectiveness on a leadership-class supercom
 puter architecture. Our evaluation, relative to the vendor stack, includes
  an analysis of resource manager complexity, system noise, networking and 
 application performance.\n\nTag: Accelerators, FPGA, and GPUs, Reliability
