ARM HPC Ecosystem and the Reemergence of Vectors: Invited Paper

ARM's involvement in funded international projects has helped pave the road towards ARM-based supercomputers. ARM and its partners have collaborately grown an HPC ecosystem with software and hardware solutions that provide choice in a unified software ecosystem. Partners have announced important HPC deployments resulting from collaborations around the globe. One of the key enabling technologies for ARM in HPC is the Scalable Vector Extension, an instruction set extension for vector processing. This paper discusses ARM's journey into HPC, the current state of the ARM HPC ecosystem, the approach to HPC node architecture co-design, and details on the Scalable Vector Extension as a future technology representing the reemergence of vectors.
