MPI-IO is a set of extensions to the MPI library that enable parallel high-performance I/O operations. It provides a parallel file access interface that allows multiple processes to write to and read from the same file simultaneously. MPI-IO allows for efficient data transfer between processes and enables high-performance I/O operations on large datasets. In this seminar, we will talk about some MPI-IO advanced features such as file view, contiguous vs non-contiguous IO, hints info, independent vs collective IO, blocking vs non-blocking IO as well as MPI derived filetype and datatype.

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 The series began January 2023 and superseded similar series previously delivered by individual consortia (e.g. General Interest Seminars by SHARCNET or User Group Meeting TechTalks by SciNet).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