Programming Methods, Architectures, and Applications of Reconfigurable Technologies in HPC
SessionEighth International Workshop on Heterogeneous High-Performance Reconfigurable Computing (H2RC 2022)
DescriptionWith recent improvements in silicon fabrication technology, reconfigurable devices can now be applied to accelerate functions beyond the traditional computing domains. In-network processing and smart computational storage are just two of these approaches. We discuss both simple and more complex application examples for both of these domains, covering a network-attached ML inference appliance, a JOIN accelerator for distributed databases, and also look forward to using a cache-coherent interconnect, such as CCIX or CXL, to tackle a complex database acceleration scenario linking a computational storage unit using near-data processing to a full-scale PostgreSQL database system. Beyond these hardware architectures, the talk also examines improvements in programming tools specialized for the realization of reconfigurable computing systems. Using the open-source TaPaSCo framework as an example, advanced features such as on-chip dynamic parallelism, flexibly customizable inter-processing element communications, and host/accelerator shared virtual memory with physical page migration capabilities are discussed.
