Many proprietary high-availability (HA) software providers require users to pay
extra for system-management capabilities. Bucking this convention and driving down
costs is LINBIT, whose DRBD HA software solution, part of the Linux kernel since
2009, powers thousands of digital enterprises.
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>>
The benefits of HPC, where computing power and speed are increased dramatically by combining multiple compute nodes into tightly coordinated clusters, more>>
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>>
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!
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>>
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>>
