SUMMARY:xBGAS: An Address Space Extension for Scalable High-Performance Co
 mputing
DESCRIPTION:Posters, Research Posters\n\nxBGAS: An Address Space Extension
  for Scalable High-Performance Computing\n\nWang, Leidel, Williams, Ehret,
  Mark...\n\nThe tremendous expansion of data volume has driven the transit
 ion from monolithic architectures towards systems integrated with discrete
  and distributed subcomponents in modern scalable high-performance computi
 ng (HPC). As such, multi-layered software infrastructures have become esse
 ntial to bridge the gap between heterogeneous commodity devices. Operation
 s across synthesized components with divergent interfaces, however, inevit
 ably lead to redundant software footprints and undesired latency. A scalab
 le and unified computing platform, capable of supporting efficient interac
 tions among individual components, is therefore desired for large-scale da
 ta-intensive applications.\n\nIn this work, we introduce xBGAS, a micro-ar
 chitecture extension to the RISC-V instruction set architecture (ISA) that
  offers a scalable, global address space for high-performance, shared memo
 ry computing. The xBGAS extension provides native ISA-level support for di
 rect accesses to remote shared data blocks by mapping remote objects into 
 a system’s extended address space. We perform both software and hardware e
 valuations of the xBGAS design.\n\nRegistration Category: Tech Program Reg
