Topics include ssh and scp, Windows PuTTy and WinSCP installation and setup for PIV on gov’t issued machines to access NCCS systems.

ADAPT

Accessing ADAPT Instructional Video

Learn how to access and login to a virtual machine on the ADAPT system. ADAPT users can customize their VM experience by selecting their preferred operating system. Instructions include how to access an ADAPT Linux VM from Linux and Windows operating systems, and how to access a Windows ADAPT VM directly through a web browser.

Anaconda on ADAPT

Anaconda is now available globally on ADAPT which means users no longer need to install Anaconda down their personal directory locations. This instructional includes descriptions of where the system default Anaconda is located, steps to load different Anaconda modules, activating and deactivating a conda environment, and how to create and customize a new conda env or leverage an existing one.

Accessing a Windows VM through Guacamole

It’s now quicker and easier to connect to an ADAPT windows virtual machine using Guacamole. This instructional leads the user through steps to achieve startup of their windows virtual machine.

Basics of MPI job startup, how to troubleshoot basic issues with starting MPI jobs, and the interaction between MPI startup and SLURM. The target audience is Discover and Explore users who run MPI based applications.

This video instructional describes how to perform a secure file transfer between the Discover systems and a local windows workstation. The user will be given instruction on how to download and install the PuTTy terminal emulator software as well as the WinSCP secure GUI file transfer utility necessary to accomplish file transfers.

Earth Science and NCCS

This TT describes ways that remote sensing data here at NCCS is used for Earth science applications. Topics include Science Context intro, preprocessing steps to prepare geospatial data, and Model building and processing.

EVIZ

EViz consists of two Python-based tools, eViz and iViz, that provide a simple way to visualize a wide variety of data sources. eViz is a CLI-driven static plotting tool configurable with YAML files. iViz is a Jupyter Notebook-based tool with a Bokeh backend for providing an interactive exploration of data sources.

Foundation Model

The term Foundation Model has been widely used in news media and science articles but what does it really mean? At the core of it a Foundation Model is a heavily pre-trained model that can usually be fine tuned with a small amount of data and compute to address specific science questions. There are many foundation models for weather, computer vision, and for language (ChatGPT, etc are all Foundation Models) as well as an increasing number of model for discipline specific science including science projects supported by the NCCS. In this presentation we will discuss current popular Foundation Models which can be fine tuned for satellite data to do tasks such as land cover classification. We will then demonstrate a method of fine-tuning foundation models for continuous and classification tasks using Jupyter Notebooks, and provide links to our Github repo where you can access many foundation models including DINOv2, DOFA, TerraMind, and Prithvi-EO, and the example notebooks. We will go over the compute expended in the original training of these models and compare it to the how much is needed for fine-tuning for specific applications. At the end we are happy to answer any questions you might have about basic implementations of Foundation Models

Gitlab

The latest features and capabilities of Gitlab are presented.

Jupyter

Jupyter is now available on ADAPT. Project Jupyter products include Jupyter Notebook, Jupyter kernels, JupyterHub, and JupyterLab, the next generation version of Jupyter Notebook. This instructional gives an Overview describing Jupyter Hub, it’s configuration on ADAPT, and how to signin and start up the Jupyter Hub server.
full page

Topics include starting up a JupHub server, exploring the JupyterLab console, as well as conda environments and how they are available to Jupyter Notebooks within a user session.

Kubernetes

Linux FAQs

In this video, NCCS staff will address common helpdesk FAQs and answer basic Linux questions submitted by the user community.
LINUx 101 FAQS

ML/AI

Machine learning provides a statistical inference based on the inputs provided by the user in which algorithms learn relationships between input data and output results. This TT will give an overview of machine learning topics such as: Benefits of using ML, the S/W that supports ML, ML frameworks in python, ML Algorithms, and an example Jupyter Notebook run.

NCCS and GPU Programming

This video explores the GPU resources available at NCCS and NAS. It offers an introduction to GPU programming, covering the GPU stack, the basics of GPU architecture, and an overview of various programming models. Perfect for anyone looking to understand the essentials of GPU technology.

Open OnDemand

A demonstration of a different way to consume HPC resources will be presented.

Please note: This is not operational within NCCS at this time. This video is for general Technical Sharing of Information to our Users.

SLides

User Applications

The focus of this TT is the types of User applications available on NCCS resources. Also discussed will be module usage and a light touch on other types of packaged envs.
