GCC 10 vs. GCC 11 Compiler Performance On AMD Zen 3

After recently looking at the early LLVM Clang 12 compiler performance on the AMD Ryzen 9 5950X, in today's benchmarking is a look at how the GCC 11 compiler performance is looking in its near final state compared to GCC 10 under a variety of build CFLAGS/CXXFLAGS configurations on the AMD Zen 3 desktop.

Linux 5.13 Should See HP Platform Profile Support

Linux 5.12 is bringing the initial infrastructure around ACPI Platform Profile support and with this kernel it's implemented for newer Lenovo ThinkPad and IdeaPad laptops. The support allow for altering the system's power/performance characteristics depending upon your desire for a speedy, quiet, or cool experience. With Linux 5.13 it looks like HP laptops with this capability will begin to see working Platform Profile support too.

Early Ubuntu 21.04 Benchmarks Point To Some Slides In Performances But Overall Flat

In yesterday's Linux distribution benchmark comparison on a Ryzen 9 5900X, you may have noticed some of the Ubuntu 21.04 development benchmarks coming in slower than Ubuntu 20.10 but overall a tight race. That is something I've seen now on other systems too -- such as these results to pass along today from an Intel notebook with the latest Ubuntu 20.10 vs. 21.04 development tests.

ZLUDA v2 Released For Drop-In CUDA On Intel Graphics

One of many interesting and original open-source projects to be started in 2020 was ZLUDA, an open-spurce drop-in CUDA implementation for Intel graphics. ZLUDA - developed independent of Intel and NVIDIA - is built atop Intel's oneAPI Level Zero interface (hence the name, ZLUDA) and allows for unmodified CUDA applications to run on Intel UHD/Xe Graphics hardware with near-native performance. Well, that's the goal at least but with the initial ZLUDA release were a number of support limitations.

Arch-Based SalientOS + EndeavourOS Take On Clear/Fedora/Ubuntu With The Ryzen 9 5900X

Given the recent release of Arch Linux based EndeavourOS and a Phoronix Premium supporter recently pointing out SalientOS as another interesting Arch-based Linux distribution, here are benchmarks showing how these easy/quick to deploy Arch based operating systems with sane defaults compare to that of Ubuntu, Fedora Workstation, and Intel's own Clear Linux. This round of February 2021 Linux benchmarking was carried out on an AMD Ryzen 9 5900X desktop stemming from premium member feedback.

Microsoft Contributes Integrity Improvements To Linux 5.12

Microsoft engineers continue increasing their contributions to the Linux kernel where it makes business sense for them, such as in the case of securing the Azure cloud given that around 50% or more of the instances run Linux. With Linux 5.12 there are integrity subsystem improvements coming from Microsoft.

The State Of ROCm For HPC In Early 2021 With CUDA Porting Via HIP, Rewriting With OpenMP

Earlier this month at the virtual FOSDEM 2021 conference was an interesting presentation on how European developers are preparing for AMD-powered supercomputers and beginning to figure out the best approaches for converting existing NVIDIA CUDA GPU code to run on Radeon GPUs as well as whether writing new GPU-focused code with OpenMP device offload is worthwhile.

Oracle Solaris 11.4 SRU30 Is The Biggest Update We've Seen In A While

Oracle continues maintaining Solaris 11.4 with monthly stable release updates but there still is no public sign of anything past 11.4 for this operating system that was once exciting during the Sun Microsystems days. But with this week's 11.4 SRU30 release, at least there are many package updates.

Mesa Lands New Single File Cache To Help Steam's Pre-Compiled Shaders, Space Savings

Mesa's on-disk shader cache, which is used for speeding up game load times by avoiding the redundant recompiling of shaders on successive loads and also helping performance for software that compiles shaders on-the-fly, is seeing a big improvement with Mesa 21.1. Mesa 21.1-devel merged this weekend the new single file cache implementation.

Linux 5.12 Git Seeing New Code Land Following Winter Storm

While the first week of a new merge window is often one of the busiest times for Linus Torvalds in overseeing the Linux kernel, until last night there was no actual Linux 5.12 code being pushed into the Linux Git repository. Linus was offline most of the week due to winter storms preventing him from pushing to the Git repository and interacting much with the mailing list.
