In the last of three articles on HDF5, we explore performing parallel I/O with the use of HDF5 files.

Fortran development is still progressing, with a new version scheduled to release in 2018. In this article, we look at Fortran 2008 and the upcoming Fortran 2015.

Fortran 90 was only the start. The next two iterations – 95 and 2003 – pulled Fortran into a new era of programming languages.

Fortran comprises a huge body of software in high-performance computing. We look at Fortran’s evolution into a modern HPC language.

Editors, particularly command-line editors, are an important tool for high-performance computing systems administrators. We point out some editor options with little to no bloodshed.

Working with containers in high-performance computing can be difficult; a new container named Singularity comes to the rescue.

What does the developer of Singularity have to say?

Understanding the I/O pattern of your application is the starting point for improving its I/O performance, especially if I/O is a fairly large part of your application’s run time.

High-performance computing begins with understanding what you are trying to achieve, the assumptions you make to get there, and the resulting boundaries and limitations imposed on you and your HPC system.

Benchmarks have been misused by both users and vendors for many years, but they don’t have to be the evil creature we all think them to be.
