The Next Big Wave.

Funded by the National Science Foundation’s Innovative High-Performance Computing Program and building on the success of Blue Waters, Delta is the most performant GPU computing resource in NSF’s portfolio, making it a prime destination for advanced scientific research.

More Than CPUs.

NCSA continues its contributions to supercomputing innovation with Delta, a computing and data resource that balances cutting-edge graphics processor and CPU architectures that will shape the future of advanced research computing.

NCSA integrated Delta into the national cyberinfrastructure ecosystem through the Advanced Cyberinfrastructure Coordination Ecosystem: Services & Support (ACCESS) program and partner with the Science Gateways Community Institute to provide platform access serving a broad range of needs. Boasting a non-POSIX file system with a POSIX-like interface, Delta allows applications to reap the benefits of modern file systems without rewriting code. And the Delta team advances accessibility, providing greater usability of the interfaces by the widest possible audience, and in helping emerging research areas, such as computational archaeology and digital agriculture, take advantage of new computing methods.

Delta Might Be Right for You If:

  • you need access to the latest NVIDIA GPUs for your accelerated code
  • you’re interested in transitioning from CPU to GPU while running a CPU workload
  • you have large memory demands for a shared-memory application such as in-memory databases, etc.

Delta provides ample professional development opportunities to adapt research applications to more optimally use its key features. Researchers who currently have GPU projects or are considering migrating to GPU architectures will find ready assistance in migrating the work to Delta.
