We have collected presentations from IXPUG workshops, annual meetings, and BOF sessions, and made them accessible here to view or download. You may search by event, keyword, science domain or author’s name. The database will be updated as new talks are made available.
The Aurora exascale system is currently being deployed at Argonne National Lab. The system, utilizing Intel’s new Data Center Max Series GPUs (a.k.a. PVC) and Xeon Max Series CPU with HBM, will provide a uniquely powerful platform for leading-edge HPC, AI, and data-intensive computing applications. Scientists at Argonne National Laboratory, in collaboration with the Exascale Computing Project, Intel, and several other institutions, are preparing several dozen applications and workflows to run at scale on the Aurora system. This talk will present an overview of the Aurora system and highlights from the experience of preparing applications for the system. In addition, promising early performance results on the Aurora hardware will be shown.
