The ALCF and Intel are collaborating to build the Aurora exascale supercomputer. To help advance application development for the system, the ALCF recently launched Sunspot, a two-rack testbed machine that is equipped with the exact same hardware as Aurora.

In this episode of Intel's Code Together podcast, Argonne's Tim Williams and Venkat Vishwanath join Intel's Tony Mongkolsmai to discuss the new Sunspot testbed and how research teams are using it to optimize code performance in preparation for early science runs on Aurora.
