  • Building MPI Clusters on Chameleon: A Practical Guide

    Simplifying Distributed Computing Setup with Jupyter, Ansible, and Python
    by Michael Sherman

    Running distributed applications across multiple nodes is a common need in scientific computing, but setting up MPI clusters can be challenging, especially in cloud environments. In this post, we'll explore a template for creating MPI clusters on Chameleon that handles the key configuration steps automatically, letting you focus on your research rather than infrastructure setup.

  • If At First You Don't Succeed, Try, Try, Again...? Insights and LLM-Informed Tooling for Detecting Retry Bugs in Software Systems

    Using Chameleon to Hunt Down Elusive Retry Bugs in Software Systems
