Frequently Asked Questions

How do I request access to DeltaAI?

• Pre-Production: DeltaAI is currently in pre-production. To request access during the pre-production period, please submit a support request and be sure to mention the DeltaAI “pre-production period”.

• After Pre-Production: 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.

(base) garnold@fj-grace2:~/c$ ./xthi
-bash: ./xthi: cannot execute binary file: Exec format error


(base) garnold@fj-grace2:~/c$ file xthi      # confirm binary file architecture
xthi: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, with debug_info, not stripped


(base) garnold@fj-grace2:~/c$ uname -i       # confirm system architecture
aarch64

Why do some of the DeltaAI-related syntaxes include “gh”?

The “gh” in some syntaxes refers to “Grace Hopper”; DeltaAI is powered by the NVIDIA GH200 Grace Hopper Superchip.
