Open-Source OpenCL Adoption Is Sadly An Issue In 2017

While most of the talks that take place at the annual X.Org Developers' Conference are around the exciting progress being made across the Linux graphics landscape, at XDC2017 taking place this week at Google, the open-source GPGPU / compute talk is rather the let down due to the less than desirable state of the open-source OpenCL ecosystem.

NVIDIA Offers Update On Their Proposed Unix Device Memory Allocation Library

James Jones of NVIDIA presented this morning at XDC2017 with their annual update on a new Unix device memory allocation library. As a reminder, this library originated from NVIDIA's concerns over the Generic Buffer Manager (GBM) currently used by Wayland compositors not being suitable for use with their driver's architecture and then the other driver developers not being interested in switching to EGLStreams, NVIDIA's original push for supporting Wayland.

How AMD EPYC & Intel Xeon Gold Compare To Various Amazon EC2 Cloud Instances

Last week we began with our EPYC 7601 Linux benchmarking of this high-end AMD server CPU featuring 32 cores / 64 threads per socket. Earlier this week were also some 10-year old Opteron vs. EPYC benchmarks and power efficiency tests while the latest in our EPYC Linux testing is seeing how the new AMD processor compares to various Amazon EC2 cloud instances.

Opteron vs. EPYC Benchmarks & Performance-Per-Watt: How AMD Server Performance Evolved Over 10 Years

By now you have likely seen our initial AMD EPYC 7601 Linux benchmarks. If you haven't, check them out, EPYC does really deliver on being competitive with current Intel hardware in the highly threaded space. If you have been curious to see some power numbers on EPYC, here they are from the Tyan Transport SX TN70A-B8026 2U server. Making things more interesting are some comparison benchmarks showing how the AMD EPYC performance compares to AMD Opteron processors from about ten years ago.

Banshee Engine Planning For Linux Support In Q4

Banshee has been a promising C++14-written, multi-threaded open-source game engine featuring Vulkan support. When the Vulkan support was added at the start of the year the plan was to see the Linux support added to the game engine in Q2. Well, it looks like in Q4 we could see the Linux client finally materialize.
