ALMOS (Advanced Locality Management Operating System) is an open-source research operating system currently under development at the SoC department of the LIP6 Laboratory (UPMC Sorbonne Universités). This new research operating system has been started from scratch and it is targeting cc-NUMA multi/many-cores. It is intended to investigate the scalability of the different components of an operating system on a current and future many-cores.
ALMOS is currently used in several research projects and Master degree courses at LIP6 and UPMC. Its development is currently a work-package in the SHARP (Scalable Heterogeneous ARchitecture for Processing) MEDEA+ European project which is an HPC oriented project leaded by Bull. ALMOS is also deeply used in TSUNAMY - an ANR national research project aiming to co-design a new security solution for information processing on multi/many-core processors. ALMOS has been originally developed as a part of the TSAR MEDEA+ European project.
ALMOS allows several shared-memory parallel applications to scale up to +1024 cores on the TSAR (Tera-Scale ARchitecture) single-chip cc-NUMA many-core.
