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>>
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>>
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>>
Linux-based container infrastructure is an emerging cloud technology
based on fast and lightweight process virtualization. It provides
its users an environment as close as possible to a standard Linux
SIDUS (Single-Instance Distributing Universal System) was developed at
Centre Blaise Pascal (Ecole normale supérieure de Lyon,
Lyon, France), where one administrator alone is in charge of 180 stations.
Emmanuel Quemener started SIDUS in February 2010, and he significantly
cut his workload for administering this park of stations.
SIDUS is now in use at the supercomputing centre PSM more>>
This year's Reader's Choice issue was truly fun to put together. No,
not just because you do all the work (voting), but because it's great
to get a feel for what our community is buzzing about. Based on your
feedback, we've given you all the data again this
year, with percentages and rankings, plus we tried to include as many
of your less-popular responses as possible. more>>
Nowadays, high-performance server software (for example, the HTTP accelerator) in most
runs on multicore machines. Modern hardware could provide 32, 64 or more CPU
cores. In such highly concurrent environments, lock contention sometimes hurts
overall system performance more than data copying, context switches and so
When your data and work grow, and you still want to produce results in a
timely manner, you start to think big. Your one beefy server reaches its
limits. You need a way to spread your work across many computers. You
truly need to scale out.

This week IBM released a bunch of new hardware, including 8 new Power Systems, 3 PureSystems models, and new storage technology. This is good news for small and medium businesses, because it means the same powerful hardware that powers Watson (http://www-03.ibm.com/innovation/us/watson/) is now available at prices designed to compete with commodity hardware from other vendors. more>>
Many of my previous articles have looked at software packages
that do scientific calculations and generate scientific results. But,
columns of numbers are nearly impossible to make sense of—at least, by
regular human beings. So what can you do? The answer is visualization. more>>
That's always been the case for me. I'm a map freak. I own hundreds of
paper maps in various specialties, plus many atlases, books on geography,
geology and other geo-obsessions. But I'm no longer an edge case, because
maps are proving to be essential on smartphones, which today approaches a
billion or more people. Digital maps on phones are now among the core
portfolio of smartphone apps, alongside voice, text, calendar and contacts.
What could be more mobile about a phone than a map to help the user look
things up and get around?
As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
