The Wasmer 1.0 alpha release is now available for running WebAssembly programs anywhere. Wasmer is about providing a universal runtime for WebAssembly (WASM) that can run across platforms / operating systems and also embed into other programming languages. Wasmer leverages WebAssembly principles to provide safety around untrusted code on top of its other design features...

As part of re-testing all hardware prior to major GPU/driver launches, here is a look at the latest NVIDIA OpenCL/CUDA performance on Linux -- complementing the recent Blender 2.90 benchmarks and the latest NVIDIA vs. AMD Linux gaming performance. In still waiting to find out when we will get any NVIDIA Ampere hardware for Linux testing, I have been having some benchmarking fun and extended this to a 24-way graphics card comparison back to Maxwell in looking at not only the raw GPU compute performance but also the performance-per-Watt / power consumption and GPU thermal values.

Following a lot of comments on the Ubuntu Discourse, Mark Shuttleworth has chimed in with his thoughts and work moving forward...

The Linux 5.0 to 5.9 kernel benchmarking posted this week showed TensorFlow Lite running slower since the Linux 5.5 kernel... On top of looking at the new Linux 5.9 regressions, I also spent some time bisecting and figuring out what happened for TensorFlow Lite last year that has at least for the system under test caused it to run slower for all the kernel releases this year as shown in the aforelinked article.

Polishing up Qt 5.15 since its May release is now Qt 5.15.1 as the first point release in this last Qt5 series ahead of Qt 6.0 later this year...

It should come as little surprise in general but making use of Advanced Vector Extensions (AVX) for multimedia encode/decode is a big deal for performance. While one could hope that by 2020 most open-source encoders were already extensively utilizing AVX(2), that isn't yet the case with the latest being AOM-AV1 picking up another optimization...

Recently carrying out some benchmarks of all major kernel releases from Linux 5.0 through Linux 5.9 ended up yielding some surprising performance changes with the in-development 5.9 kernel. Here's details on this historical look at the kernel performance and what's going on with the Linux 5.9 kernel slowdowns.

It's been widely expected AMD will launch their next-generation RDNA 2 graphics cards and Zen 3 processors in Q4 as they previously reported as well as leaks pointing to October reveal dates. Today the company is sharing actual dates for said announcements...

Proposed last year were a set of patches aiming to improve the Intel virtual GPU "vGPU" performance in para-virtualized cases by having optimizations around the shared memory region between the guest and Intel GVTg code. With optimizing the workload PV submission and PPGTT PV updates, the glxgears performance could improve by 30~50% while for large media/3D workloads was more around a 4% average improvement...

Intel's September 2020 security advisories were posted today and include four security advisories around nine vulnerabilities...

When looking at the performance of Zink's OpenGL over Vulkan implementation just about one year ago the performance had a lot to be desired. But since then they have patches bringing it all the way to OpenGL 4.6 compared to the OpenGL 2.1 days and there has also been a lot of work on the performance. The performance at least for select operations is now turning out better than even the developers were expecting...

The V3DV open-source Vulkan driver being developed by consulting firm Igalia for the Raspberry Pi Foundation is nearing official support for Vulkan 1.0...

Proposed earlier this summer for GNOME's Mutter was the idea of triple buffering the desktop when the GPU is running behind in order to ideally cause that extra load to ramp up the GPU clock frequencies in order to in turn get back on track with rendering the desktop on-time. A third version of that work is now brewing albeit too late to see with the imminent GNOME 3.38.0 release...

A few days ago I published a deep dive into the CPU and GPU performance with Blender 2.90 as a major update to this open-source 3D modeling software. Following that I kept on testing more and older NVIDIA GPUs with the CUDA and OptiX back-end targets to now have an 18-way comparison from Maxwell to Turing with the new Blender 2.90...
