Call for Proposals: NeoSDF 2026

The Pittsburgh Supercomputing Center is inviting researchers to submit proposals for collaborative scientific projects on the Neocortex HPE Superdome Flex (SDF).

With 24 TiB of shared memory, the SDF is well suited to an important class of problems that are difficult or impossible to run on distributed-memory clusters—for example, analyses on very large graphs that must remain resident in memory; large-scale bioinformatics pipelines; and irregular or sparse computations. It is also a strong fit for in-memory AI-readiness preparation of very large datasets for downstream use on the Neocortex Cerebras CS-3 or on Bridges-2.

Through this call, the Neocortex team is looking to identify research efforts where this capability can make a meaningful difference. Successful applicants will be paired with a Neocortex collaborator who will help them set up their working environment and run their project on the system.

The Neocortex HPE Superdome Flex (SDF) features 32 Intel Xeon Platinum 8280L CPUs with 28 cores (56 threads) each, 2.70-4.0 GHz, 38.5 MB cache, 24 TiB RAM, aggregate memory bandwidth of 4.5 TB/s, and 204.6 TB aggregate local storage capacity with 150 GB/s read bandwidth. The SDF can provide 1.6 Tb/s from PSC filesystems. Jobs can be submitted via SLURM or Open OnDemand. The use of Apptainers is supported. The Pegasus WMS (workflow management system) is available.

Applications will be accepted on a rolling basis from May 18, 2026 to June 7, 2026 (midnight anywhere on Earth). Notifications will be sent by June 15, 2026.
