Colloquium 2024 Parallel Programming: MPI I/O Basics

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 and read to the same file simultaneously. MPI-IO allows for efficient data transfer between processes and enables high-performance I/O operations on large datasets. It also provides additional features such as collective I/O, non-contiguous access, and file locking. This seminar will talk about some basic features and the API routines of MPI-IO in MPI parallel programming.
