Amazon EC2 Cloud Benchmarks vs. AMD Ryzen, Various AMD/Intel Systems

For putting the AMD Ryzen 7 Linux performance in additional perspective and showing how various Amazon EC2 cloud instances compare to bare metal hardware, here are fresh benchmarks of many different Amazon EC2 instance types compared to various Linux systems in our lab. This comes down to a 29-way comparison of different cloud instances and bare metal systems.

Radeon RX 580: AMDGPU-PRO vs. DRM-Next + Mesa 17.2-dev

Last week I posted initial Radeon RX 580 Linux benchmarks and even AMDGPU overclocking results. That initial testing of this "Polaris Evolved" hardware was done with the fully-open Radeon driver stack that most Linux enthusiasts/gamers use these days. The AMDGPU-PRO driver wasn't tested for those initial articles as it seems to have a diminishing user-base and largely focused for workstation users. But for those wondering how AMDGPU-PRO runs with the Radeon RX 580, here are some comparison results to DRM-Next code for Linux 4.12 and Mesa 17.2-dev.

Testing F2FS With Its Multi-Drive Capabilities

Late last year F2FS picked up multiple device support for this Flash-Friendly File-System. This F2FS multi-drive capability isn't native RAID support like Btrfs but just allows a single F2FS file-system to span multiple devices. But it's more than that in that block allocation and the garbage collection policy is modified to boost I/O performance by taking advantage of the multiple SSD/flash devices.

AMDGPU-PRO 17.10 OpenCL vs. NVIDIA Shows Problems

Last week I began posting a number of AMD Radeon RX 580 Linux benchmarks but not covered so far has been the OpenCL compute performance considering the Clover-based compute stack isn't good enough for benchmarking and is basically unmaintained these days by AMD. Meanwhile, their ROCm stack is still being brought up and is not yet fully-opened nor optimized yet for performance. Thus for those with desktop cards looking for basic OpenCL support are left with the AMDGPU-PRO hybrid driver with its closed-source OpenCL driver. In this article are some fresh OpenCL benchmarks of AMDGPU-PRO on the RX 580 and other Radeon GPUs compared to NVIDIA with its Linux OpenCL driver.

LLVM Still Working Towards Apache 2.0 Relicensing

LLVM developers have been wanting to move from their 3-clause BSD-like "LLVM license" to the Apache 2.0 license with exceptions. It's been a while since last hearing about the effort while now a third round of request for comments was issued.
