The design space for such a scheduler is very large and so there are many options that Slurm provides to accommodate a variety of different clusters/policies. </p> https://docs.rcac.purdue.edu/blog/2025/08/08/job-priority-and-scheduling/ Tue, 12 May 2026 19:37:04 +0000 RCAC Documentationhttps://docs.rcac.purdue.edu/blog/2025/08/08/job-priority-and-scheduling/ Guangzhen Jin Announcements Documentation Search Software Catalog User Guide <h1>Introducing the New RCAC Documentation Website</h1> <p>We are excited to announce the launch of the redesigned <strong>RCAC Documentation Website</strong> — a unified, searchable hub for everything you need to use Purdue's high-performance computing resources. The new site is built around three goals: <strong>find information fast</strong>, <strong>stay current automatically</strong>, and <strong>learn as a community</strong>. Whether you are a first-time user or an experienced researcher, here is what is waiting for you.</p> https://docs.rcac.purdue.edu/blog/2026/04/20/rcac-docs-website-intro/ Wed, 29 Apr 2026 18:17:08 +0000 RCAC Documentationhttps://docs.rcac.purdue.edu/blog/2026/04/20/rcac-docs-website-intro/ Geoffrey Lentner Josh Remender Arun Seetharam Guangzhen Jin Login Software VS Code <h1>VS Code on RCAC Resources</h1> <p>Visual Studio Code (VS Code or Code) is a popular IDE growing in usage in HPC. It is particularly useful for less-technical researchers (relative to say, Vim), because of it's remote development capabilities.</p> https://docs.rcac.purdue.edu/blog/2025/08/08/vscode_rcac/ Wed, 29 Apr 2026 18:17:08 +0000 RCAC Documentationhttps://docs.rcac.purdue.edu/blog/2025/08/08/vscode_rcac/ Jacob Verburgt Geoffrey Lentner Anaconda Conda Python Software <h1>Conda vs Anaconda</h1> <p>On RCAC community clusters we deploy modules for both <code>conda</code> and <code>anaconda</code>. These are both separate distributions of the "conda" package manager. The <code>conda</code> module points towards the Miniforge distribution of conda (https://github.com/conda-forge/miniforge), while the <code>anaconda</code> module loads the official Anaconda, Inc. distribution of conda (https://www.anaconda.com/download). </p> <p>Although these two distributions behave similarly, the components within them vary slightly:</p> https://docs.rcac.purdue.edu/blog/2025/09/24/conda-anaconda/ Fri, 24 Apr 2026 18:04:05 +0000 RCAC Documentationhttps://docs.rcac.purdue.edu/blog/2025/09/24/conda-anaconda/ Ryan DeRue Slurm Workflows <h1>Checkpointing in a Preemptible Environment</h1> <h3>What is Preemption?</h3> <p>In the context of computing, preemption refers to the act of stopping or pausing one process to allow another process to run, and we say that a task, X, preempts another task, Y, when X pauses Y to allow itself to run. We can use this concept of preemption in an HPC environment to maximize the utilization of the resources in the cluster by allowing low priority jobs to be preempted by higher priority jobs since this allows us to be lenient with the resource limitations placed on the low priority jobs.</p> https://docs.rcac.purdue.edu/blog/2025/10/16/preemption-checkpointing/ Thu, 16 Oct 2025 20:14:54 +0000 RCAC Documentationhttps://docs.rcac.purdue.edu/blog/2025/10/16/preemption-checkpointing/
