  • Women in IT Awards USA winner: Margaret Dawson, Red Hat

    Margaret has led teams at companies ranging from startups to Fortune 500 firms including Amazon, Microsoft and HP. She grew up in Detroit and began her career in the automotive industry, an experience that helped her feel at home in the similarly male-dominated technology sector.

    She has a passion for mentoring women in technology and has made it her mission to share the lessons she has learned with others and to mentor them in their own journeys.

  • How do tools affect culture?

    Most of the DevOps community talks about how tools don’t matter much. The culture has to change first, the argument goes, which might modify how the tools are used.

    I agree and disagree with that concept. I believe the relationship between tools and culture is more symbiotic and bidirectional than unidirectional. I have discovered this through real-world transformations across several companies now. I admit it’s hard to determine whether the tools changed the culture or whether the culture changed how the tools were used.

  • GPU Accelerated SQL queries with PostgreSQL & PG-Strom in OpenShift-3.10

    In the OpenShift 3.9 GPU blog, we leveraged machine learning frameworks on OpenShift for image recognition. And in the How To Use GPUs with DevicePlugin in OpenShift 3.10 blog, we installed and configured an OpenShift cluster with GPU support. In this installment, we will create a more sophisticated workload on the cluster – accelerating databases using GPUs.

    One of the key parts of any machine learning algorithm is the data (often referred to as the data lake/warehouse, stored as structured, semi-structured or unstructured data).

    A major part of machine learning pipelines is the preparation, cleaning, and exploration of this data. Specifically removing NAs (missing values), transformations, normalization, subsetting, sorting, and a lot of plotting.

  • Reducing the use of non-glibc allocators in Fedora

    Memory allocation for applications is a bit of a balancing act between various factors including CPU performance, memory efficiency, and how the memory is actually being allocated and deallocated by the application. Different programs may have diverse needs, but it is often the kind of workload that the application is expected to handle that determines which memory allocator performs best. That argues for a diversity of memory allocators (and allocation strategies) but, on the other hand, that complicates things for Linux distributions. As a result, Fedora is discussing ways to rein in the spread of allocators used by its packages.

  • Copr has a brand new API

    New Copr version is here and after several months of discussions and development, it finally brings a brand new API. In this article, we are going to see why it was needed, how it is better than previous API versions (i.e. why you should be happy about it) and try some code samples.

Kernel: Linux 4.19 and Vega 20 PowerPlay

  • Power Management Updates Land In The Linux 4.19 Kernel
    Intel's Rafael Wysocki has submitted the ACPI and power management updates today for the Linux 4.19 kernel which were subsequently merged by Linus Torvalds.
  • Linux 4.19 Git Contains a lot of Performance Impacting Spectre Mitigation Updates
    Another round of commits regarding anti-Spectre security have landed up in the Linux 4.19 kernel git tree, which may have possible performance impacts for the kernel. While Spectre is still only a somewhat theoretical threat, as its entirely too slow to be used in a serious attack, many folks are taking its future potential quite seriously and arming up against it.
  • Linux 4.19 Kernel to Receive a Ton of Audio Hardware Updates for Improved Linux Sound Capabilities
    Linux audiophiles may have something to rejoice about, as a recent pull request from SUSE’s Takashi Iwai focuses on a plethora of sound subsystem updates for the Linux 4.19 kernel, including a lot of latest hardware support and overall improvements for Linux’s audio capabilities.
  • Updated Vega 20 Open-Source Driver Patches Posted, Including PSP & PowerPlay Support
    Back in May AMD posted initial open-source "Vega 20" patches and support for that yet-to-launch graphics processor was subsequently merged for the Linux 4.18 kernel. More of the Vega 20 AMDGPU kernel driver enablement has now been posted. This latest 69,910 lines of code -- before fretting, most of that is auto-generated header files for the GPU -- notably adds PSP (Platform Security Processor) and SMU (System Management Unit) for Vega 20. With the SMU enablement code, it's also now wired in to enable Vega 20 PowerPlay support as well as related power/clocking-functionality like OverDrive overclocking is also available.
