Graphite converts confusing columns of time series data into handy diagrams, showing trends in operating system and application metrics at a glance.
Developers fed up with cryptic Makefiles should take a look at the new Meson build system, which is simple to operate, offers scripting capabilities, integrates external test tools, and supports Linux, Windows, and Mac OS X.
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.
Understanding the proliferation of data in your filesystem is key to being an administrator. Understanding file sizes and file ages and their distribution helps you tune filesystems for performance and develop policies for data management.
When building cloud environments, you need more than just a scalable infrastructure; you also need a high-performance storage component. We look at Ceph, a distributed object store and filesystem that pairs well in the cloud with OpenStack.
With some simple tuning, SSHFS performance is comparable to NFS almost across the board. In an effort to get even more performance from SSHFS, we examine SSHFS-MUX, which allows you to combine directories from multiple servers into a single mountpoint.
Hadoop 2.x and its associated tools promise to deliver big data solutions not just to the IT-heavy big players, but to anyone with unstructured data and the need for multidimensional data analysis.
Sharing data saves space, reduces data skew, and improves data management. We look at the SSHFS shared filesystem, put it through some performance tests, and show you how to tune it.
