We'll describe some sources of information you can access from within a job context, and show how they may offer insights into your job's behavior. The scope of this talk is relatively simple, DIY-type data collection, rather than more complicated profiling frameworks. For example, our systems expose power counters which your programs can query, if you're interested in carbon footprint. There are many other "gauges" and counters that can provide information about memory use, cache misses, sources of slowdowns, etc.

The Compute Ontario Colloquia are weekly Zoom presentations on Advanced Research Computing, High Performance Computing, Research Data Management, and Research Software topics, delivered by staff from three Compute Ontario consortia (CAC, SciNet, SHARCNET) and guest speakers. The series began January 2023 and superseded similar series previously delivered by individual consortia (e.g. General Interest Seminars by SHARCNET or User Group Meeting TechTalks by SciNet). The colloquia are one hour long and include time for questions. No registration is required. Presentations are usually recorded and uploaded to the hosting consortium video channel (colloquia hosted by SHARCNET go to our youtube channel).
