The Vanguard program looks to expand the potential technology choices for leadership class High Performance Computing (HPC) platforms, not only for the National Nuclear Security Administration (NNSA) and the Department of Energy (DOE), but also for the wider HPC community. Specifically, there is a need to expand the supercomputing ecosystem by investing and developing emerging, yet-to-be-proven technologies and address both hardware and software challenges together and prove-out the viability of such novel platforms for production workloads.
The first deployment of Vanguard is Astra, a prototype Petascale ARM supercomputer sited at Sandia National Laboratories. This talk will focus on the architectural details of Astra, as well as the Advanced Tri-Lab Software Environment (ATSE) and significant investments being made towards the ARM software ecosystem. Furthermore, we will share initial performance results, first experiences, and outlay several planned research activities.
