GpuTest / Re: GpuTest 0.7.0
« Last post by JeGX on February 20, 2015, 08:17:38 PM »
@jorgk: I tested on a macbook pro +  Mavericks and the test with a fixed duration works fine (with the GeForce or the Intel GPU).

Maybe it's related to a recent update? What is your version of OSX?

I will release a new update of GpuTest shortly, maybe that will fix that mysterious bug.

3D-Tech News Around The Web / Nvidia gained at the expense of AMD and Intel

"GPU shipments down in fourth quarter of 2014.

Nvidia gained at the expense of AMD and Intel. Gaming is still the market’s bright spot.

The new market report on graphics processing units (GPUs) from Jon Peddie Research (JPR) shows total shipments were down in the fourth quarter of 2014 (ending December 31, 2014). Measured on a sequential basis, Nvidia shipments were up 3%, Intel dropped 4%, AMD slipped 7%."

I never tested that kind of code but a code snippet with sub_data_read_1ui could be:

Code: [Select]
gh_gpu_buffer.map(ssbo, "GL_READ_ONLY")
x = gh_gpu_buffer.sub_data_read_1ui(ssbo, offset)
gh_gpu_buffer.unmap(ssbo)

Let me know if you need more help.

3D-Tech News Around The Web / Smart Rendering for Virtual Reality

"Researchers from Intel have been working on new methods for improving the rendering speed for modern wide-angle head-mounted displays like the Oculus Rift and Google Cardboard. Their approach makes use of the fact that because of the relatively cheap and lightweight lenses the distortion astigmatism happens: only the center area can be perceived very sharp, while with increasing distance from it, the perception gets more and more blurred. So what happens if you don't spend the same amount of calculations and quality for all pixels? The blog entry gives hints to future rendering architectures and shows performance numbers."

One week after NVIDIA disabled overclocking on their GeForce 900M mobility lineup, a representative of the company has reported that NVIDIA will be bringing back the disabled feature for their overclocking enthusiasts on the mobility front. On the GeForce Forums, he writes, "We heard from many of you that you would like this feature enabled again. So, we will again be enabling overclocking in our upcoming driver release next month for those affected notebooks. If you are eager to regain this capability right away, you can also revert back to 344.75."

"The Linux kernel sits at the core of all Linux-based operating systems and is produced in an open-source, multi-stakeholder process. It's a process that has evolved over the last two decades, with a steady flow of new developers pouring into the community and contributing code. In a new report released by The Linux Foundation Feb. 18, the pace of Linux code contribution is detailed with data looking at eight Linux kernel releases in 15 months—beginning with the Linux 3.11 kernel, released in September 2013, and ending with Linux 3.18, which debuted Dec. 8, 2014."
