Frequently Asked Questions

How do I request access to DeltaAI?

  • DeltaAI Early Access Period (mid-August to mid-September): The DeltaAI system will start an NSF mandated 30-day early access period. If you are interested in participating in the early access period, please submit a support request and be sure to mention the DeltaAI “early access period”.

  • After the Early Access Period: Most DeltaAI compute resource allocations are awarded through the ACCESS program. See the Delta Allocations page to learn more about the different allocation methods and how to submit an allocation request to each.

Why does my binary file return “Exec format error”?

This error indicates that the binary file doesn’t match the system architecture. You should recompile the application to match the system architecture.

In the following example, the file is x86_64 architecture and needs to be recompiled to match the system’s aarch64 architecture.

-bash: ./xthi: cannot execute binary file: Exec format error


(base) garnold@fj-grace2:~/c$ file xthi      # confirm binary file architecture
