Efficient Parallel IO on ARCHER PrerequisitesNew
Tue 20 Mar - Wed 21 Mar 2018
Description
- Please note that although this course is being hosted at Cambridge, it is being organised and run by EPCC at the University of Edinburgh.
- This hands-on course explores a range of issues related to parallel IO. It uses ARCHER and its parallel Lustre file system as a platform for the exercises; however, almost all the IO concepts and performance considerations are applicable to any parallel system.
- The first day of the course will cover the MPI-IO standard, developing IO routines for a regular domain decomposition example. It will also briefly cover higher-level standards such as HDF5 and NetCDF which are built on top of MPI-IO.
- The second day will concentrate on performance, covering how to configure the parallel file system and tune the MPI-IO library for best performance. Case studies from real codes will be presented.

Prerequisites
The course assumes a good understanding of basic MPI programming in Fortran, C or C++. Knowledge of MPI derived datatypes would be useful but not essential.
