--- 

p2rng is a modern header-only C++ library for parallel algorithmic (pseudo) random number generation supporting OpenMP, CUDA, ROCm and oneAPI. Playing fair, mostly required for debugging and unit testing, is one of the unique features of p2rng. That means using the same seed and distribution you always get the same sequence of random numbers on all supported platforms. p2rng provides parallel versions of STL’s std::generate() and std::generate_n() algorithms with the same interface. In this seminar we first start with a quick review of preliminary concepts about algorithmic random number generators in general and parallelization techniques in particular. Then we continue with the standard way of generating random numbers with STL algorithms and how we can turn them into parallel version using p2rng.

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 The series began January 2023 and superseded similar series previously delivered by individual consortia (e.g. General Interest Seminars by SHARCNET or User Group Meeting TechTalks by SciNet).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).
