The pdsh  parallel shell tool lets you run a command across multiple nodes in a cluster.

Inexpensive, small, portable, low-power clusters are fantastic for many HPC applications. One of the coolest small clusters is the ClusterHAT for Raspberry Pi.

The most fundamental tool needed to administer an HPC system is a parallel shell, which allows you to run the same command on a series of nodes. In this article, we look at pdsh.

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

We look into some everyday questions that administrators with Ceph clusters tend to ask: What do I do if a fire breaks out or I run out of space in the cluster?

Getting started in the HPC world requires learning to write parallel applications and learning to administer and manage clusters. We take a look at some ways to get started.

Adding and subtracting software from a running cluster can be tricky; however, many application packages can be added or removed easily with a few tools and some simple tricks.
