Going on two years ago PathScale open-sourced their EKOPath 4 Compiler Suite. This Fortran/C/C++ compiler suite hasn't seen widespread adoption since then outside of some scientific circles and other select high-performance areas, but PathScale hasn't stalled in advancing their compiler software that is also still available commercially. PathScale has been preparing to release EKOPath 5.0, which is the subject of today's benchmarks.
The first development release of Phoronix Test Suite 4.4-Forsand is now available for those interested in open-source benchmarking and automated testing. This major quarterly update is poised to introduce new features that will benefit all users from hardware enthusiasts to enterprise customers.
Courtesy of Intel's Open-Source Technology Center are 13 new Linux micro-benchmarks that have been created based upon the Phoronix Test Suite and OpenBenchmarking.org. These brand new test profiles provide test coverage of systemd boot performance, timing of various common system tasks, GPU residency times, PowerTop wake-up monitoring, and much more.
While there's already been articles looking at the Nouveau NVIDIA driver and AMD Radeon driver on the forthcoming Linux 3.8 kernel, up today are some early computational benchmarks of this new kernel. From an Intel Core i7 "Ivy Bridge" system, some general-purpose Linux benchmarks were conducted from the Linux 3.5 kernel release through the latest Linux 3.8 Git development kernel.
With last week's release of LLVM 3.2, here are new benchmarks of LLVM 3.2 with the Clang C/C++ compiler front-end. The LLVM/Clang 3.2 performance using last week's source code releases were compared to the earlier LLVM/Clang 3.1 release and then for competition was the GCC 4.7.2 stable release and the latest GCC 4.8.0 development snapshot.
After already sharing the free response survey results, here are the results from the structured part of this year's annual GNOME User Survey.
After yesterday sharing the general feedback submitted by over a thousand GNOME users (Part 1, Part 2) from the 2012 GNOME User Survey about their views on the popular Linux desktop environment, here's all of the responses to another one of the questions. The question came down to what features of GNOME are most important from your personal use and would not like them to go away.
The first batch of user feedback was published this morning from the 2012 GNOME User Survey. Here's now the second and final batch of GNOME user feedback collected through the annual desktop survey. The results from the actual survey questions will be published later this week.
With the 2012 GNOME User Survey now officially over, here's the start of the results. In this posting are the first (of two) batches of feedback that users supplied while filling out the survey. This year there were 4,494 people participating in the annual yet independent GNOME survey. Of the nearly 4.5k respondents, 1,950 of them also provided feedback with this first batch consisting of the first one thousand responses. The results from the survey in full will also be published this week.
In this article are benchmarks of six different desktops (Unity, GNOME Shell, GNOME Classic, KDE Plasma, Xfce, and LXDE) on five different GPU/driver configurations (Radeon, Catalyst, Intel, NVIDIA, and Nouveau) running the very latest Ubuntu 13.04 "Raring Ringtail" development packages to look at the latest state of the Ubuntu Linux gaming OpenGL performance.
After last year discovering a major Linux kernel power regression that was widely debated until the Phoronix test automation software bisected the problem to get to the bottom of the situation, there's more active power regressions today on the Linux desktop. As I've mentioned on Twitter and in other articles in weeks prior there's a few regressions, but one of them for at least some notebooks is causing a very significant increase in power consumption. This situation that remains unresolved as of the Linux 3.7 kernel can cause the system to be going through about 20% more power.
The latest ARM Cortex-A15 benchmarks on Phoronix is an extension of the earlier compiler testing from this modern ARM CPU found on the Samsung Exynos 5 Dual within the Samsung Chromebook. In this round of performance testing, the LLVM/Clang compiler performance is compared to recent releases of the GNU Compiler Collection on this latest-generation ARM hardware.
Due to there being much interest in the ARM Cortex A15 benchmarks on Linux, namely with the Samsung Chromebook and its Samsung Exynos 5 Dual, here's a weekend special providing some GCC compiler benchmarks of this new ARM chip.
In this article are benchmarks of the latest Linux 3.7 kernel development code of the EXT4, XFS, and Btrfs file-systems.
Following last month's Btrfs file-system tuning benchmarks, in this article are a similar set of tests when stressing the EXT4 file-system with its various performance-related mount options. Here are a number of EXT4 benchmarks from Ubuntu 12.10 with different mount option configurations.
Earlier this week I shared some updated benchmarks of the latest development code for LLVM/Clang 3.2 on an Intel Core i7 processor. Now from this same setup to complement the LLVM 3.1/3.2 benchmarks are results of the GCC 4.7.2 compiler, the latest GCC 4.8 development snapshot, and benchmarks of GCC when using LLVM's DragonEgg 3.1/3.2-SVN optimizer plug-in.
The latest ARM Linux benchmarks to share at Phoronix is a comparison of Ubuntu 12.10, Linaro 12.10, Fedora 17, and Arch Linux when running from the dual-core Cortex-A9 OMAP4460-based PandaBoard ES development board.
With LLVM/Clang 3.2 being released next month and the code branching occurring this month, here's some new benchmarks from the latest SVN development snapshot as of this weekend. LLVM/Clang 3.2 SVN benchmarks were compared to the earlier LLVM 3.1 and 3.0 releases for reference.
This month from CPUs based upon AMD's new Piledriver micro-architecture I have delivered results of compiler tuning on AMD's Open64 compiler as well as GCC bdver2 tuning. That initial testing from an AMD FX-8350 Eight-Core processor didn't show any big boost out of the "bdver2" target with the new BMI/TBM/F16C/FMA3 instruction set extensions. Testing in this article from the AMD FX-8350 are GCC compiler benchmarks of the 4.6.3, 4.7.2, and 4.8.0 development snapshots to look for performance improvements on this new high-end AMD processor when using the very latest GCC compiler code.
With this week's unveiling of the FX-8350 eight-core processor being based on AMD's new Piledriver architecture, in this article are benchmarks when testing out the Piledriver "bdver2" optimizations within AMD's own Open64 compiler.
As some more benchmarks from the Calxeda EnergyCore ECX-100 ARM Server -- a.k.a. the "5-Watt Linux Server" -- to share this weekend, here is a ARMv7 Cortex-A9 GCC compiler performance comparison.
Earlier this week I posted new Reiser4 file-system benchmarks that compared the non-mainline file-system against EXT4, Btrfs, XFS, and ReiserFS. Continuing in the Linux file-system performance theme, in this article are more Btrfs benchmarks from that same system but when using the early Linux 3.7 development kernel and trying out different Btrfs mount/tuning options.
With the initial Linux results for the AMD A10-5800K Trinity APU now out of the way along with the Radeon HD 7660D graphics performance, in this article are some benchmarks looking at the impact of compiler tuning for the Piledriver cores using the common GCC compiler and testing different CPU micro-architecture targets.
While the Reiser4 file-system has been in-development for the better part of the past decade, it still hasn't been merged into the mainline Linux kernel. Reiser4 is still out-of-tree, doesn't see much new development activity by its limited developers, and the file-system remains tarnished due to its founder, Hans Reiser, being a convicted murderer. However, Edward Shishkin the former Namesys employee, does continue to drive its development forward. Reiser4 was recently updated to work with the more modern Linux 3.5 kernel.
For those that have never benchmarked the performance differences between GCC's different optimization levels, here are some recent test results comparing the performance differences when using an AMD FX-8150 processor with GCC 4.7.2.
With LLVM 3.2 set for release in mid-December, the time to benchmark this next major compiler infrastructure release paired with the Clang C/C++ compiler is approaching. Well, that time has already come; up this weekend are some benchmarks of the Intel Core i7 3960X "Sandy Bridge Extreme Edition" on Ubuntu 12.04 when comparing LLVM/Clang 3.1 to their latest SVN development code for LLVM/Clang 3.2 as of this week.
As the latest AMD Bulldozer Linux benchmarks, here are updated figures on compiler tuning for the FX-8150 processor when using GCC 4.7.1.
It was 25 years ago today, on 15 September 1987, that Version 11 Release 1 of the X Window System (a.k.a. X11) was released. X11 has evolved a long way since then, but this 25-year-old technology out of MIT remains at the heart of every Linux desktop.
On this Friday we have a freelance open-source opinion article that was written by Ciprian Khlud. This developer, who uses C# among other languages at his place of employment along with a combination of Windows and Linux, argues why the Mono open-source ECMA CLI/C#/.NET implementation is actually desirable for Linux.
In continuation of last week's OpenGL benchmarks under Unity, GNOME, KDE, Xfce, and LXDE desktops from Ubuntu 12.10, here are benchmarks looking at the 2D performance of these different Linux desktop environment choices when testing both the Intel UXA and SNA acceleration back-ends.
