Going to SIGGRAPH? Be sure to check out some amazing demo's, presentations, prizes and more. Khronos has a news conference, five BOFs (COLLADA, OpenCL, WebGL, OpenGL ES & OpenGL) and a huge OpenGL party, all happening on Tuesday next week. Full details can be found here, and the party details can be found here.
Valve Software has updated their Linux blog to report that the OpenGL version of Left 4 Dead 2 is now running fastest on Linux (315 fps). Surprisingly, given all the attention Valve has paid to Direct3D tuning over the years, even on Windows, the OpenGL version of the game now runs faster than Direct3D (304 fps vs. 270 fps) due to "overhead per batch in Direct3D which does not affect OpenGL on Windows".
OpenGL Insights includes a detailed OpenGL 4.2 and OpenGL ES 2.0 pipeline map as a two-sided 14x18 inch detachable color poster. The map cross-references the OpenGL 4.2 and ES 2.0 specs. The ES pipeline is relevant to both ES and WebGL developers. You may also download a high resolution PDF version directly from the OpenGL Insights website.
Watch Alina Alt explain compute API interoperability with OpenGL (using CUDA and OpenCL APIs) and delve into interoperability at a system level (or review the slides). Alina explains challenges and benefits of dedicating one GPU for compute and another for graphics, how different system configurations affect data transfer between two GPUs, and how it translates into application design decisions helping to enable an efficient, cross-GPU interoperability between compute and graphics contexts.
You are cordially invited to attend the OpenGL BOF on Wednesday 6-7pm in the Gold Ballroom in the JW Marriott hotel to celebrate 20 years of OpenGL with us. You’ll learn what is new and upcoming with the OpenGL API. We will also have two special guest speakers. Rich Geldreich from Valve will talk about their awesome project “Steam’d Penguins” that brings Steam and OpenGL games to Linux. Rich will be speaking about their challenges and successes porting Left 4 Dead 2 to OpenGL on Linux. Kurt Akeley, co-founder of SGI and of the OpenGL API will give his perspective on 20 years of OpenGL development. Right after the BOF we’ll open the doors for the OpenGL 20th anniversary party, with free drinks and various prizes to win. For more information, visit our Siggraph webpage.
Come to the Aug 8th OpenGL BOF 2th Anniversary party and YOU get the presents! There will be lots of prizes being given away including 100s of Special 20th Anniversary edition “OpenGL T-shirts; numerous raffles prizes – such as books and cool tech gadgets and 150 “OpenGL 20th Anniversary” Pint glasses as prizes for the basketball free throws and ping pong playoffs at the OpenGL 20th Anniversary party. We look forward to seeing you there!
Tech Source, Inc. has announced a conduction cooled and rugged version of its Condor 3000x XMC processor targeted at general purpose graphics processing unit (GPGPU) applications. The Condor 3000x-cc XMC card is based on the AMD RadeonTM E6760 AIB. With 576 GFLOPs of peak single precision floating point performance and 480 individual processing units (shaders), the Condor 3000 graphics processor is particularly well suited for highly parallel computations and other GPGPU applications such as image analysis, radar, sonar, and video surveillance.
Imagination Technologies, a leading multimedia technologies company, announces the latest IP cores in its ground-breaking PowerVR Series6 GPU core family. The PowerVR G6230 and G6430 GPU IP cores are the latest in a growing family of PowerVR Series6 GPU cores and deliver high compute efficiency while minimising power and bandwidth requirements. Rogue meets requirements for compute APIs including OpenCL 1.x and Renderscript Compute, delivering an optimal balance of performance versus power consumption for mobile and embedded devices. All members of the Series6 family are designed to support all features of the latest graphics APIs including the next generation of the OpenGL ES API, OpenGL 3.x/4.x, and DirectX10 with certain family members extending their capabilities to full WHQL-compliant DirectX11.1 functionality.
Tom's Hardware tests OpenCL acceleration in Adobe PhotoShop CS6, Musemage, GIMP and a pre-release version of Corel's AfterShot Pro, across five system configurations and looks for patterns in the results including scaling based on GPU horsepower.
