Using Large Language Models (LLMs) on Swan

HCC has recently installed new tools for working with Large Language Models (LLMs) on Swan. This includes both a system-wide Ollama module and LM Studio Open OnDemand App. In addition to the Ollama module, a few public and common models (e.g., llama, gpt-oss, deepseek, etc.) are also available system-wide via the`mldata` module.

More information can be found on the Using LLMs on HCC resources page.

Reducing file quota impact of conda environments

Conda environments often consist of numerous tiny and small files. These small files often will reach the file limits of 5 million files on HCC’s filesystems. All of these small files may also cause a substantial load on the metadata servers for the respective filesystems, resulting in some performance loss as a result.

HCC now has a guide on how to convert a conda environment into a single file using Apptainer available HERE .
