Running Caffe AlexNet/GoogleNet On Some CPUs Compared To NVIDIA CUDA

With working on some Broadwell-EP Linux comparison benchmarks this weekend, as part of that onslaught of benchmarks I decided to run the CPU-only Caffe build on a few different Intel CPUs. For fun, afterwards I checked to see how the performance compares to Caffe with CUDA+cuDNN on a few Maxwell/Pascal GPUs.

Windows 10 vs. Linux Radeon Software Performance, Including AMDGPU-PRO & RadeonSI

As alluded to earlier and on Twitter, the past few days I have been working on a fresh Windows 10 vs. Ubuntu Linux graphics/gaming performance comparison. This time it's looking at the latest Radeon performance using an R9 Fury and RX 480. Tests on Windows were obviously done with Radeon Software Crimson Edition while under Linux were the two latest AMD/RTG Linux driver options: the hybrid AMDGPU-PRO driver and the fully open-source driver via Linux 4.8 and Mesa 12.1-dev.

Making Use Of eBPF In The Mainline Linux Kernel

One of the exciting innovations within the Linux kernel in the past few years has been extending the Berkeley Packet Filter (BPF) to become a more generalized in-kernel virtual machine. The eBPF work with recent versions of the Linux kernel allow it to be used by more than just networking so that these programs can be used for tracing, security, and more.

RadeonSI OpenGL Performance Has Evolved A Lot Since Early 2015

Yesterday I posted some benchmarks showing how the AMDGPU / R9 Fury performance has jumped up in the past few months just since the April release of Ubuntu 16.04 LTS. For those wondering how the open-source AMD OpenGL performance has evolved over the longer term, I took a Radeon R9 270X graphics card and re-did tests going back to Ubuntu 15.04 for looking at the RadeonSI Gallium3D performance for the past year and a half.

Upcoming Linux Tests With A $300 Broadwell-EP Xeon CPU

Unfortunately Intel Corp hadn't sent over any Broadwell-EP hardware earlier this year when launching these new Xeon E5-2600 V5 server processors nor when it came to the high-end consumer Broadwell-E processors. However, I ended up buying a Xeon E5-2609 v4 Broadwell-EP this week for a new system and will be running a variety of upcoming tests.

Linux 4.8 Intel P-State vs. CPUFreq Scaling Driver/Governor Benchmarks

Given the underlying work that's been happening in the CPUFreq/scheduler area and the introduce of the new Schedutil CPUFreq governor, I decided to run some fresh performance benchmarks of P-State and CPUFreq with the different governor options when testing from a Linux 4.8 Git kernel atop the current Fedora 25 development packages and using a Core i5 Skylake processor.

More Details On PC-BSD's Rebranding As TrueOS

Most Phoronix readers know PC-BSD as the BSD operating system derived from FreeBSD that aims to be user-friendly on the desktop side and they've done a fairly good job at that over the years. However, the OS has been in the process of re-branding itself as TrueOS.
