Fall 2023 Seminars
In the fall we will resume our high-performance computing (HPC) seminar series. We begin with two identical sessions of the HPC Quickstart session, and then learn about parallelism, interactive computing, containers, and data structures. Notes from the Quickstart are available online (you must be on the Lehigh network to access this).

| title | High-Performance Computing: Quickstart |
|---|
| Description: This seminar provides an introduction to high-performance computing (HPC) resources at Lehigh along with a walkthrough of the essential ingredients required to build research computing projects. Participants will learn the best practices for designing small, exploratory projects so that they can be scaled up to answer questions that require big data and parallel computations. This course will teach newcomers how to use Linux and Python to complete a simple but powerful research computing project. Instructor: Ryan Bradley |

| title | High-performance computing: Easy Parallel Computations |
|---|
| Description: Many exploratory research computing projects will eventually grow to require larger amounts of computational resources, either because they need to demonstrate that they are correct and reproducible, or to answer larger, more complicated research questions. This seminar will teach you to use the Lehigh high-performance computing (HPC) cluster to build parallel scientific software for answering larger questions using simple Linux tools along with the HPC scheduler (named SLURM).

| title | High-Performance Computing: Interactive Computing and Visualization |
|---|
| Description: Research computing projects of all sizes can benefit from interactive tools which make it easy to develop, debug, and visualize code and data on our local high-performance computing (HPC) systems. This seminar will demonstrate the use of a web portal to interact with your data and code, with a particular emphasis on connecting Jupyter notebooks to very large datasets and parallel computations.

| title | High-Performance Computing: Containers and Reproducibility |
|---|
| Description: Research computing projects can have a large impact if they are portable and easy to share with new collaborators. In this seminar, you will learn how to package your scientific computations in a Linux-based container system (Docker and Apptainer). Containers can make it easy to take your work to larger public supercomputing centers, and improve the reproducibility and openness of your scientific software. Instructor: Ryan Bradley |

|---|
| title | High-Performance Computing: Data Structures |
|---|
| Description: When a research computing project evolves to answer more nuanced questions, it inevitably requires more computational power and generates more data. This seminar will teach you the best practices for storing large, complex datasets so they can easily be analyzed and mined for new insights. These methods will apply to any research questions that depend on big data. Instructor: Ryan Bradley |
