Once you have an application that works well and supplies accurate results you may ask yourself why the run-time is slow or why it doesn't scale as you expect it to.&nbsp; If your code is running in parallel using message passing or multithreading, identifying bottlenecks becomes even more complex. Fortunately, there are tools that take the guess-work out of identifying the sections of your code responsible for the bulk of your run-time.&nbsp; We’ll look at some of the most used profiling tools available for R, Python, and compiled software. Profiling output will be produced, and we'll demonstrate how to interpret the results, which should guide how to adjust your code for more efficient computation. This workshop will not be recorded.&nbsp;

The Topics in Research Computing Series includes a variety of workshops covering introductory topics like how to use the Quest cluster computer and submit array jobs, as well as more advanced computing topics such as profiling code on the cluster and running parallel R and Python code. The specific workshops offered may vary each quarter, so please check back for updates each quarter.
