The National Science Foundation (NSF) has extended operational funding for Stampede 2 through June 2023. Prior to the extension, the life of the system was expected to end in September 2022. This extension will allow the system to continue supporting world-class science for an additional nine months. 


As part of the extension, 448 of the oldest Intel Knights Landing Xeon Phi nodes will be replaced with 224 of the latest generation of Dell PowerEdge R650 two-socket servers utilizing the Intel Xeon Platinum 8380 "Ice Lake" processors. These latest servers will provide more than double the performance and almost triple the memory of the previous nodes to provide additional capability for the Stampede2 system. All 224 of the new nodes will be accessible via the "icx-normal" production queue, with development needs still being provided via the Skylake "skx-dev" queue.
