Opportunities
Computing Training from eScience and more

- Intro Programming Workshop - eScience is holding a Software Carpentry workshop on May 27th–30th (9:00 a.m. – noon each day). The workshop will teach software tools that can make researchers more effective, automate research tasks, and track research over time. Specifically, the Unix Shell, Git, and Python will be taught with a focus on reproducible research. Register here.
- Teach your own LLM - On Friday, May 23rd from 10:30 - noon in the Open Scholarship Commons, Jose Cols will lead the workshop “Teach your own LLM: Fine-tuning Models on Custom Datasets” covering how LLMs work and how to fine-tune a Llama 3 model for tasks like sentiment analysis and summarization.
External Training Opportunities
- COMPLECS: Using Regular Expressions with Linux Tools - Thursday, May 29, 2025 - 11:00 a.m. – 12:30 p.m. (Pacific Time) Regular expressions (regexes) provide a way to identify strings that match a specified pattern. They are extremely useful for preprocessing text and extracting results from high-performance computing and data science workloads. Primarily in the context of the Linux grep utility, we incrementally introduce the main features of regexes: string literals, specifying multiple characters, quantifiers, wildcards, anchors, character classes, grouping, and alternation. We also explore more advanced topics such as word boundaries, lazy and greedy matching, regex flavors (basic, extended, and Perl compatible), regexes with awk and sed, searching compressed files, and using large language models (LLMs) to create regexes. Register here!
- 8:00 - 11:30 am (Pacific time), Wednesday, May 28, 2025 - LANL is hosting an Accelerated Python Tutorial, presented by Scot Halverson from Nvidia.
