The Tri-Lab Operating System Stack (TOSS) is a Linux distribution based on Red Hat Enterprise Linux (RHEL) that was created to provide a software stack[1] for high performance computing (HPC) clusters[2] for laboratories within the National Nuclear Security Administration (NNSA).[3] The operating system allows multiple smaller systems to emulate a high-performance computing (HPC) platform.[1]
Linux distribution
The name "tri-lab" refers to the three major NNSA labs, the Lawrence Livermore National Laboratory, the Los Alamos National Laboratory, and the Sandia National Laboratories.[4]
The OS is used by NNSA computers including the El Capitan supercomputer[5] and systems using ARM architecture including the ThunderX2 system on a chip (SoC).[6] In addition to being used by the National Nuclear Security Administration (NNSA),[2] most of the systems in NASA's High-End Computing Capabiity Project, part of the NASA Advanced Supercomputing Division, were all migrated to TOSS in March 2022.[7]
Many of the software packages included in TOSS are from the RHEL repository. Additional packages are built using Fedora's Koji build system to create RPM packages.[1] The system also uses SLURM and Flux scheduling and resource management software.[1]
