SUSE Linux Enterprise High Availability Extension

Historically, data replication has been available only piecemeal through proprietary vendors. In a quest to remediate history, SUSE and partner LINBIT announced a solution that promises to change the economics of data replication. more>>

OpenPOWER

Three EU Industries That Need HPC Now

The success of High Performance Computing (HPC) relies in no small part on the OpenPOWER Foundation, which was founded in 2013. The reason this open ecosystem is so important is that it provided members open access to the IBM POWER8 technology, which resulted in huge advances in innovation. more>>

IBM LinuxONE Provides New Options for Linux Deployment

In August 2015, IBM announced LinuxONE (www-03.ibm.com/press/us/en/pressrelease/47474.wss), anchored by two new Linux mainframe servers that capitalize on best-of-class mainframe security and performance, and that bring these strengths to open-source-based technologies and the Open Source community. Th more>>

LUCI4HPC

Today's computational needs in diverse fields cannot be met by a single computer. Such areas include weather forecasting, astronomy, aerodynamics simulations for cars, material sciences and computational drug design. This makes it necessary to combine multiple computers into one system, a so-called computer cluster, to obtain the required computational power. more>>

Jailhouse

Because you're a reader of Linux Journal, you probably already know that Linux has a rich virtualization ecosystem. KVM is the de facto standard, and VirtualBox is widely used for desktop virtualization. Veterans should remember Xen (it's still in a good shape, by the way), and there is also VMware (which isn't free but runs on Linux as well). more>>

April 2015 Issue of Linux Journal: High-Performance Computing

High Performance: a Relative Term

My Pebble watch has several orders of magnitude more power than the mainframe computers used by NASA to land astronauts on the moon an more>>

High-Availability Storage with HA-LVM

In recent years, there has been a trend in which data centers have been opting for commodity hardware and software over proprietary solutions. Why shouldn't they? It offers extremely low costs and the flexibility to build an ecosystem the way it is preferred. The only limitation is the extent of the administrator's imagination. more>>

Readers' Choice Awards 2014

It's time for another Readers' Choice issue of Linux Journal! The format last year was well received, so we've followed suit making your voices heard loud again. I couldn't help but add some commentary in a few places, but for the most part, we just reported results. Please enjoy this year's Readers' Choice Awards! more>>

Integrating Trac, Jenkins and Cobbler—Customizing Linux Operating Systems for Organizational Needs

Organizations supporting Linux operating systems commonly have a need to build customized software to add or replace packages on production systems. This need comes from timing and policy differences between customers and the upstream distribution maintainers. more>>

How YARN Changed Hadoop Job Scheduling

Scheduling means different things depending on the audience. To many in the business world, scheduling is synonymous with workflow management. Workflow management is the coordinated execution of a collection of scripts or programs for a business workflow with monitoring, logging and execution guarantees built in to a WYSIWYG editor. more>>

A Process for Managing and Customizing HPC Operating Systems

High-performance computing (HPC) for the past ten years has been dominated by thousands of Linux servers connected by a uniform networking infrastructure. The defining theme for an HPC cluster lies in the uniformity of the cluster. more>>
