  • Tryton Unconference 2019: In Marseille on the 6th & 7th of June

    We will go in the sunny city of Marseille in south of France on the 6th and 7th of June. Contrary to previous editions of the Tryton Unconferences the coding sprint will be organized during the two days preceding the conference.

  • Argonne Looks to Singularity for HPC Code Portability

    Scaling code for massively parallel architectures is a common challenge the scientific community faces. When moving from a system used for development—a personal laptop, for instance, or even a university’s computing cluster—to a large-scale supercomputer like those housed at the Argonne Leadership Computing Facility, researchers traditionally would only migrate the target application: the underlying software stack would be left behind.

    To help alleviate this problem, the ALCF has deployed the service Singularity. Singularity, an open-source framework originally developed by Lawrence Berkeley National Laboratory (LBNL) and now supported by Sylabs Inc., is a tool for creating and running containers (platforms designed to package code and its dependencies so as to facilitate fast and reliable switching between computing environments)—albeit one intended specifically for scientific workflows and high-performance computing resources.

  • Mitogen v0.2.4 released

    Mitogen for Ansible v0.2.4 has been released. This version is noteworthy as it contains major refinements to the core libary and Ansible extension to improve its behaviour during larger Ansible runs.

    Work on scalability is far from complete, as it progresses towards inclusion of a patch held back since last summer to introduce per-CPU multiplexers. The current idea is to exhaust profiling gains from a single process before landing it, as all single-CPU gains continue to apply in that case, and there is much less risk of inefficiency being hidden in noise created by multiple multiplexer processes.

OpenBSD 6.5 Released With RETGUARD, OpenRSYNC

OpenBSD 6.5 was released today, about one week ahead of schedule for this security-minded BSD operating system. OpenBSD 6.5 is bringing several prominent new features including RETGUARD as its new stack protector and OpenRSYNC as its ISC-licensed in-progress replacement to rsync. OpenBSD 6.5's new RETGUARD functionality aims to be a better stack protector on x86_64 and AArch64 with instrumenting every function return with better security properties than their traditional stack protector.

  • Announcing Akademy 2019 in Milan, Italy (September 7th - 13th)
    Akademy 2019 will be held at the University of Milano-Bicocca in Milan, Italy, from Saturday the 7th to Friday the 13th of September. The conference is expected to draw hundreds of attendees from the global KDE community to discuss and plan the future of the community and its technology. Many participants from the broad Free and Open Source software community, local organizations and software companies will also attend. KDE e.V. is organizing Akademy 2019 with unixMiB — the Linux User Group of the University of Milano-Bicocca. unixMiB aims to spread Open Source philosophy among students.

  • Intel Iris Gallium3D Picks Up Conservative Rasterization Support
    On top of Intel's new open-source OpenGL driver seeing some hefty performance optimizations, the Iris Gallium3D driver has picked up another OpenGL extension ahead of the Mesa 19.1 branching.  Iris Gallium3D now supports INTEL_conservative_rasterization alongside the existing support in the i965 driver. INTEL_conservative_rasterization is the several year old Intel extension for seeing if all fragments are at least partially covered by a polygon rather than the default rasterization mode of including fragments with at least one sample covered by a polygon.
