SUSE To Be Taken Private By Its Largest Shareholder

Posted on by

The SUSE organization has changed hands many times over the years… From being its own independent company to the notable acquisition by Novell two decades ago. Over the past decade SUSE has changed hands between Attachmate, Micro Focus, EQT Partners, and then went public back in 2021 on the Frankfurt Stock Exchange. Now two years later its being taken private…

AMD Isn't Done Yet Optimizing The Mesa RadeonSI Driver For Workstation OpenGL

Posted on by

While over the past several years AMD landed numerous significant improvements to their RadeonSI driver for benefiting OpenGL workstation use-cases, that quest isn’t yet over and more optimizations continue to be pursued. There are additional optimizations on the horizon for the RadeonSI Gallium3D driver for benefiting OpenGL on Linux workstations…

Amazon's New EC2 M7a AMD EPYC "Genoa" Instances Deliver Leading Performance In The AWS Cloud

Posted on by

While back in November was when AWS originally announced new EC2 instances powered by 4th Gen AMD EPYC “Genoa” processors, only this week did they bring their M7a general purpose instances to a general availability state where anyone can access them. Being very impressed with 4th Gen EPYC bare metal as well as with Azure’s HPC cloud, I fired up some benchmarks of the new Genoa-powered EC2 M7a instance compared to the new M7i instances powered by Intel Xeon Scalable “Sapphire Rapids” as well as showing how the competition is to Amazon’s in-house Graviton ARM-based server processors.

Intel QAT Adapted For Zstd To Provide Big Performance/Efficiency Wins

Posted on by

While Intel has maintained the QATzip open-source compression library for demonstrating data compression using QuickAssist Technology (QAT) with DEFLATE/LZ4/LZ4s, Intel has also been working on QAT’ed Zstd for achieving some sizable victories in performance and power efficiency…

Initial AVX10.1 Support Merged Into The GCC Compiler

Posted on by

It was less than one month ago that Intel announced AVX10 as the successor to AVX-512. In that time Intel engineers have begun posting AVX10.1 enablement patches for GCC as well as beginning AVX10 discussions for the LLVM compiler stack. Overnight already the initial AVX10.1 enablement code has been merged into the GNU Compiler Collection…

StarFive VisionFive 2 Quad-Core RISC-V Performance Benchmarks

Posted on by

SiFive’s HiFive Unmatched development board was interesting when it began shipping in 2021 with 16GB of RAM and four U74-MC RISC-V cores along with one S7 core. But pricing was rather steep at $665 USD. Fast forward two years, the StarFive VisionFive 2 has begun to enjoy wide availability and for $100+ this RISC-V development board features a quad-core RISC-V processor via the StarFive JH7110 SoC with integrated GPU, up to 8GB of RAM, HDMI 2.0 output, dual Gigabit Ethernet, dual USB 3.0 ports, and more for around $100 USD. Here are some benchmarks of this most interesting RISC-V single board computer in the ~$100 space to be released yet.

GCC Compiler Adds Software Workaround To Avoid Intel Downfall Performance Hit

Posted on by

With the Intel Downfall vulnerability made public last week (also known as GDS – “Gather Data Sampling”) there can be a sizable hit to AVX workloads making use of the GATHER instructions. For helping to lower the impact of Downfall/GDS on mitigated systems, Intel has made a change to the GNU Compiler Collection to disable GATHER generation in vectorization for Intel CPU families affected by this vulnerability…
