Meet with the Open OnDemand project team at this informal monthly meeting! All topics are welcome, and team members will drop into a breakout session with you to cover site-specific issues if needed.

Hosted by the community, tips and tricks webinars share best practices of all things Open OnDemand. They take place on the first Thursday of every month at 1 p.m. ET.  Recordings of previous events are available on the Open OnDemand website. 

All users of advanced cyberinfrastructure, whether they develop their own software or use 3rd party applications, should understand fundamental parallel computing concepts. In this webinar we cover supercomputer architectures, the differences between threads and processes, implementations of parallelism (e.g., OpenMP and MPI), strong and weak scaling, limitations on scalability (Amdahl’s and Gustafson’s Laws) and benchmarking.

Knowledge of Linux is indispensable for using advanced CI. While GUIs are becoming more prevalent, being able to work at the command line interface (CLI) provides the greatest power and flexibility. In this session, we assume that participants are already comfortable with basic Linux operations such as creating, deleting and renaming files, and navigating between directories.

Many computational and data processing workloads require pre-processing of input files to get the data into a format that is compatible with the user’s application and/or post-processing of output files to extract key results for further analysis. While these operations could be done by hand, they tend to be time-consuming, tedious and, worst of all, error prone. In this session we cover the Linux tools awk, sed, grep, sort, head, tail, cut, paste, cat and split, which will help users to easily automate repetitive tasks.

HPC systems are shared resources, therefore all users must be aware of the complexity of working in a shared environment and the implications associated with resource management and security. This module also addresses two essential and related sets of skills that should be a part of everyone’s toolbox, but that are frequently overlooked: (1) solving problems on your own leveraging online resources and (2) how to best work with the help desk or user support by properly collecting the information that can be used to help resolve your problem.
