DeltaAI is a companion system to Delta. Powered by the NVIDIA GH200 Grace Hopper Superchip, DeltaAI provides powerful compute capabilities for simulation and data science.

DeltaAI enables scientists and researchers to tackle the world’s most challenging problems by accelerating complex artificial intelligence (AI) and high-performance computing applications running terabytes of data. The system triples NCSA’s AI-focused computing capacity and greatly expands the capacity available within the NSF-funded advanced computing ecosystem. NCSA utilizes advanced web-based interfaces that make DeltaAI more accessible to the growing community of research domains employing AI methods in their research, furthering NCSA’s mission to democratize high-performance computing.

 

Complete User Documentation

The complete user documentation for DeltaAI is available at DeltaAI User Documentation — UIUC NCSA DeltaAI User Guide

Status Updates and Notices

DeltaAI system status, planned outages, and maintenance information is available through ACCESS.

Quick Start Guide

This information is for users who are adept at using an HPC system and are only interested in the basic DeltaAI workflow.

Getting Started with High-Performance Computing

There are no specific prerequisite courses or high-performance computing (HPC) experience required before using DeltaAI. However, if you are unfamiliar with using a HPC cluster, it is highly recommended that you take NCSA’s short tutorial Using an HPC Cluster for Scientific Applications before continuing.

Browse NCSA’s HPC-Moodle for a full list of HPC training opportunities including self-paced tutorials.

Getting Help

  • For ACCESS allocations issues, create a ticket via the ACCESS Help page (ACCESS log in required). You can browse other ACCESS support resources on the ACCESS Support page (ACCESS log in not required).

  • Use the NCSA Help Portal for all other issues, regardless of allocation type. Powered by Jira Service Manager (JSM), in this portal you can:

    • Submit help request tickets.

    • Search knowledge base articles to resolve common issues faster.

    • Monitor the status of your tickets.

    • Respond to NCSA staff as they work to resolve your tickets.

  • Refer to the JSM User Job Aid for information on how to navigate the help center.

  • The NCSA Help Portal is the preferred method to submit requests. However, if you run into problems using it, you can still email help@ncsa.illinois.edu for support. When emailing a request to help@ncsa.illinois.edu please follow these guidelines:

    • A descriptive subject line starting with DeltaAI (for example, “DeltaAI: srun isn’t working.”)

    • In the email body, include:

      • The UserID you use to log into the system.

      • The name of the allocation account that you use to submit jobs.

      • Approximately when (date/time) the issue occurred.

      • What you were trying to do and how you tried to do it.

      • Why you think it isn’t working.

      • Commands or scripts you ran, in enough detail to reproduce the problem (text files are preferred).

      • The output and/or error messages you got (text files are preferred).

      • Did you install any modules? If so, which ones? (run module list and paste the output into the message)

      • If your command or script worked in the past, when did it stop working?

      • Any other approaches you’ve tried.

      • Any other information you think might be relevant.
