Research Computing Seminars
Spring 2023 Seminars
The research computing seminars offered in the Spring semester are designed to lead participants through a survey of the wide range of available research computing techniques that they can apply to their training and research. Over the course of this seminar series, students will be expected to imagine how their projects can be formulated to take advantage of both small and large scale computation. We will begin with the end in mind, by first creating a map of the high-performance computing (HPC) resources available to the research community at Lehigh. After this introduction we will study the Linux basics required to effectively work with code and data, and then tackle the scheduler (SLURM) that we use to share a large HPC platform among many users. The final three sessions will provide a deeper dive into interactive computing with the Open OnDemand portal, building your own highly-portable software containers, and using Python for advanced computation on the cluster. Attendees are welcome to bring their own research problems and questions to these sessions.
These sessions cooperate with a larger body of seminars hosted by Library and Technology Services. Of particular interest are the Python and R seminars, since the skills that you learn in these classes can translate into much larger problems that require high-performance computing.

| Jan 31 & Feb 2 | Research Computing Resources at Lehigh Description: This seminar provides an overview of the Research Computing resources available to the Lehigh research community. We introduce high-performance computing (HPC) and provide a guide for gaining access to research computing resources, specifically the hardware, software, and training required to support new research. We also provide an overview of external computing resources provided by the National Science Foundation (NSF). Instructor: Ryan Bradley |
| Feb 7 & Feb 9 | Linux Basics for Research Computing Description: Linux is a free and open source operating system that is the operating system of choice of the world's leading supercomputers as well as LTS high-performance computing (HPC) clusters and some computer labs at Lehigh. This session will provide an introduction to the Linux environment, using the command line, logging into remote systems, and transferring data, and the use of terminal-based text editors. This seminar is designed for researchers who want to use Linux resources to support their work. Instructor: Ryan Bradley Download the slides here. |
| Feb 14 & Feb 16 | Using the SLURM Scheduler on Lehigh’s HPC Cluster Description: Lehigh uses the SLURM scheduler to ensure that many researchers can effectively share our high-performance computing (HPC) resources. This session provides a hands-on introduction to SLURM so that participants can learn to translate their research questions into hardware requests on an HPC platform by formulating, submitting, and monitoring batch jobs. This session may also be useful for researchers who also leverage external HPC platforms in their work. Instructor: Ryan Bradley |
| Feb 21 & Feb 23 | Introduction to the Open OnDemand Portal Description: Open OnDemand (OOD) is an NSF-funded open-source high-performance computing (HPC) portal developed by the Ohio Supercomputing Center. The goal of OOD is to provide an easy way for system administrators to provide web access to their HPC resources. This seminar introduces OOD to access interactive applications such as MATLAB, Jupyter Lab/Notebooks, and RStudio on Lehigh's HPC cluster. The portal provides a more fully-featured user interface to the cluster, complementing the standard, terminal-based method for remotely accessing the cluster. Instructor: Ryan Bradley |
| Feb 28 & Mar 2 | Bring Your Own Software: Containers on HPC Resources Description: Container systems provide the tools for researchers to more easily build and migrate their software to diverse computing platforms. Singularity is an open-source container engine designed to bring operating system-level virtualization to scientific and high-performance computing. In this seminar, we’ll provide an overview of Singularity and teach you to build your own software in a container system for use on Sol. These techniques can improve the durability and reproducibility of your research. Instructor: Ryan Bradley |
| Mar 7 & Mar 9 | Advanced Python on HPC Resources Description: This session will provide a tour of advanced Python methods that can be useful on the cluster. Python often serves as a glue for binding high-performance computation to complex data structures and intricate workflows. This seminar will briefly survey the NumPy and SciPy mathematical libraries, using HDF5 to generate complex data files, and the method for extending Python with C extension modules.
