Intel's Gallium3D Driver Gains Optimization For Helping With Java OpenGL Performance

Tuesday 10th of September 2019 08:14:48 AM
In our recent Mesa 19.2 benchmarks of Intel's old and new (Gallium3D) OpenGL Linux drivers one of the rare areas where the new "Iris" driver performed behind the classic driver was with "j2dbench" that stresses the Java OpenGL pipeline. At the time it was unknown why the new driver was performing subpar for this Java graphics test, but now at least there's one optimization so far in addressing that shortcoming...

CompuLab's Airtop 3 Is The Most Powerful Fan-Less Computer We've Tested Yet

Monday 9th of September 2019 07:35:00 PM
The past month and a half we have been putting CompuLab's Airtop 3 computer through some demanding benchmarks and a variety of endurance workloads. With the Airtop 3 under test loaded with an 8-core / 16-thread Xeon processor, NVIDIA Quadro RTX 4000 graphics, and 64GB of RAM with NVMe SSD storage there were some concerns over thermal throttling and if this fan-less industrial PC design could really deal with the generated heat. But after all of this testing, the Airtop 3 continues running strong and another shining example of CompuLab's engineering strength.

  • [Mozilla] Restricting third-party iframe widgets using the sandbox attribute, referrer policy and feature policy

    Adding third-party embedded widgets on a website is a common but potentially dangerous practice. Thankfully, the web platform offers a few controls that can help mitigate the risks. While this post uses the example of an embedded SurveyMonkey survey, the principles can be used for all kinds of other widgets. Note that this is by no means an endorsement of SurveyMonkey's proprietary service. If you are looking for a survey product, you should consider a free and open source alternative like LimeSurvey.

DM-Clone Target Added To Linux 5.4 For Efficient Remote Replication Of A Block Device

Added to the device mapper (DM) code with the Linux 5.4 kernel is an interesting addition that benefits those wanting to carry out some interesting use-cases around remote replication of block devices. As explained in the original patch proposal for dm-clone, "dm-clone produces a one-to-one copy of an existing, read-only device (origin) into a writable device (clone): It presents a virtual block device which makes all data appear immediately, and redirects reads and writes accordingly. The main use case of dm-clone is to clone a potentially remote, high-latency, read-only, archival-type block device into a writable, fast, primary-type device for fast, low-latency I/O. The cloned device is visible/mountable immediately and the copy of the origin device to the clone device happens in the background, in parallel with user I/O." Read more

This was the first OpenShift Commons Gathering to take place in Italy. The standing room only event hosted 11 talks in a whirlwind day of discussions. Of particular interest to the community was Christian Glombek’s presentation updating the status and roadmap for OKD4 and CoreOS. Highlights from the Gathering induled an OpenShift 4 Roadmap Update, customer stories from Amadeus, the leading travel technology company, and local stories from Poste Italiane and SIA S.p.A. In addition to the technical updates and customer talks, there was plenty of time to network during the breaks and enjoy the famous Italian coffee.

  • Powering the hybrid cloud on next-generation hardware: Red Hat Enterprise Linux on IBM System Z and LinuxONE

    For more than five years we have been driving our technology strategy around the idea that the future of enterprise IT does not reside solely in an enterprise datacenter or in the public cloud. Instead the next wave of computing is built on a blend of these technologies and infrastructure: in short, the future is hybrid. The value of hybrid clouds comes from the choice it delivers, pairing the control of the corporate datacenter alongside the scale and flexibility of public clouds. We strongly feel, however, that the most valuable hybrid clouds are those that offer not only a choice of deployment type and location, but also a choice of the underlying architecture and the capacity to run on multiple public clouds. [....] With RHEL available on Z15 and LinuxONE III, this helps pave the way for the rest of Red Hat’s hybrid cloud portfolio, including Red Hat OpenShift, to emerge on IBM enterprise platforms. We’re pleased to continue our work with IBM in bringing the world’s leading enterprise Linux platform to their next-generation systems.
