• LLVM Is Playing A Big Role With Vulkan/SPIR-V Compilers

  The usage of LLVM as part of the graphics driver stack continues to be picked up now especially in the Vulkan/SPIR-V world.

  With the new NVIDIA 396 driver series there is their new "NVVM" compiler stack for SPIR-V, the IR used by Vulkan and OpenCL and now can be consumed by OpenGL 4.6 too.

• OpenBSD on my fanless desktop computer

   

  I’ve been using OpenBSD on servers for years as a web developer, but never had a chance to dive in to system administration before. If you appreciate the simplicity of OpenBSD and you have to give it a try on your desktop.

With the recent release of DragonFlyBSD 5.2 one of the prominent changes is HAMMER2 now being considered stable for most use-cases. I've been running some benchmarks of this file-system compared to alternatives on other operating systems and have some FreeBSD / Linux reference points to share.

Complementing my earlier HAMMER vs. HAMMER2 benchmarks, I ran a set of I/O tests on TrueOS and FreeBSD 11.1 as well as Ubuntu and Clear Linux. All tests were done using the same Intel Xeon E3-1280 v5 Skylake system with 256GB Toshiba RD400 NVMe SSD, same default CPU clock frequencies, etc.

With this week's release of DragonFlyBSD 5.2 this popular BSD operating system is promoting its own HAMMER2 file-system as stable. As a result, here are a few fresh benchmarks of HAMMER vs. HAMMER2 on DragonFlyBSD 5.2 while more tests are forthcoming.

HAMMER2 received many improvements during the DragonFlyBSD 5.2 development cycle to the point where they now recommend HAMMER2 as the default root file-system for non-clustered systems; the clustered mode for HAMMER2 is yet to be implemented.

On Phoronix we have been covering the HAMMER2 file-system since its inception back in 2012 and have been benchmarking it more recently since it became a fairly viable choice in DragonFlyBSD 5.0. HAMMER2 is a clean sheet design and supports online deduplication, snapshots, LZ4/Zlib compression, encryption, and other features. Our tests have been positive and in the testing of DragonFlyBSD 5.0 and 5.2 we have yet to lose any data to this file-system led by DragonFly lead developer Matthew Dillon.
