  • GCC 7.3 Released

    The GNU Compiler Collection version 7.3 has been released.

    GCC 7.3 is a bug-fix release from the GCC 7 branch containing important fixes for regressions and serious bugs in GCC 7.2 with more than 99 bugs fixed since the previous release.

    This release includes code generation options to mitigate Spectre Variant 2 (CVE 2017-5715) for the x86 and powerpc targets.

  • GCC 7.3 Released With Spectre V2 Mitigation Support

    GNU Compiler Collection 7.3 is now available as the latest GCC7 point release and the prominent changes being support for helping mitigate Spectre variant two using some new compiler switches.

    GCC 7.3 has backported Retpoline support after GCC 8.0 development code initially received the support earlier this month. This GCC support building out a patched kernel can lead to "full" retpoline protection for the system.

    The Retpoline support adds a few new compiler switches, namely -mindirect-branch= for dealing with indirect branches to avoid speculative execution.

GPU acceleration for Linux apps on Chrome OS enabled

It’s happening, and it’s happening early. GPU acceleration for Linux apps on Chrome OS has arrived. According to a recent report, Chromebooks with ‘Eve’ and ‘Nami’ baseboard should now, or very soon, be able to try GPU hardware acceleration. GPU acceleration allows applications to fully leverage the GPU of a device to better run graphic-intensive tasks, like gaming. The feature will make for a much smoother Linux apps experience for Chromebook users. Read more

Out-Of-The-Box 10GbE Network Benchmarks On Nine Linux Distributions Plus FreeBSD 12

Last week I started running some fresh 10GbE Linux networking performance benchmarks across a few different Linux distributions. That testing has now been extended to cover nine Linux distributions plus FreeBSD 12.0 to compare the out-of-the-box networking performance. Tested this round alongside FreeBSD 12.0 was Antergos 19.1, CentOS 7, Clear Linux, Debian 9.6, Fedora Server 29, openSUSE Leap 15.0, openSUSE Tumbleweed, Ubuntu 18.04.1 LTS, and Ubuntu 18.10. All of the tests were done with a Tyan S7106 1U server featuring two Intel Xeon Gold 6138 CPUs, 96GB of DDR4 system memory, and Samsung 970 EVO SSD. For the 10GbE connectivity on this server was an add-in HP NC523SFP PCIe adapter providing two 10Gb SPF+ ports using a QLogic 8214 controller. Read more
