The Expanse Early User Program (EUP) provides an opportunity for users to port, tune and optimize applications on SDSC’s upcoming Expanse supercomputer. Each Expanse standard compute node is powered by two 64-core AMD EPYC 7742 processors with 256 GB of DDR4 memory. Each GPU node contains four NVIDIA V100s (32 GB SMX2), connected via NVLINK, and dual 20-core Intel Xeon 6248 CPUs. Expanse also has four 2 TB large memory nodes.
During the EUP, users will have access to the full application and software library stack to build and test their applications, user support, and related documentation.
The Expanse filesystems are separate from the Comet filesystems and data mover nodes will be available to support data transfer between these systems.
An Expanse 101 webinar is planned early in this period so that users can get information on the software environment and running jobs on the system.
Access to the Expanse EUP will be granted via a lightweight proposal submitted via the XSEDE allocations system, XRAS.
If you have an existing XSEDE grant, access to the Early User Program will be available as an Action request, called Early User Period.
If you don't have an existing XSEDE grant, access to the Early User Program will be through an XSEDE startup allocation request.
The Expanse EUP will be limited to a 30-day period with the following requirements and goals:
