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.

HPC administrators sometimes assume that if all nodes are functioning, the system is fine. However, the most common issue users have is poor or unexpected application performance. In this case, you need a simple tool to help you understand what’s happening on the nodes.

In the continuing story of monitoring HPC systems, we look at code that measures process, network, and disk metrics.

One goal of HPC administration is effective monitoring of clusters. In this article, we talk about writing code that measures processor and memory metrics on each node.

In rapidly growing HPC installations, you need to understand what is happening within the system to make improvements or simply to justify the purchase.
