Invited Talk: Bridging Emerging Accelerator Architectures and HPC Production Systems: From Sandia Testbeds to Performance-Portable Software
DescriptionSandia National Laboratories is charting a full-stack path that takes experimental accelerator hardware from prototype testbeds into the high-performance production systems running our mission codes. In the first part of this talk, I’ll survey our hardware prototyping journey—from the Advanced Architecture Testbed lineage, through the Kingfisher wafer-scale AI/HPC engine and our El Dorado deployment, to the Vanguard systems Astra and Spectra (in partnership with NextSilicon). In the second part, I’ll dive into two software initiatives I co-lead, each designed to fuse these novel accelerators into production workflows with performance portability:• CommBench/HiCCL, a unified micro-benchmarking and hierarchical collective-communication framework for multi-GPU, multi-NIC nodes• A Kokkos execution space for the NextSilicon Maverick-2 dataflow accelerator
