GPU Switching Goes For The Gold: Mainline Inclusion
,----[ Quote ]
| At the start of the month we talked about
| GPU switching coming to Linux in a crude
| form that allowed notebooks with dual GPUs
| (one being a low-power, low-performance
| integrated chip and the other being the
| more performance-oriented GPU that's power
| hungry) to be switched from without the
| need for a reboot in Linux. This initial
| work was just a collection of hacks by
| David Airlie and it required VT switching
| after killing the X Server, etc. It also
| didn't power down the unused GPU. However,
| as the days passed, this code did more and
| delayed GPU switching came too.

| ATI Radeon HD 2000/3000/4000 series
| graphics processors, Jerome Glisse of Red
| Hat has also been busy at work on a shader
| compiler for the R600/700 ASICs with the

xf86-video-nv Driver Updated, First In Months
,----[ Quote ]
| Most Linux distributions this year will be
| switching over to the community-created
| Nouveau graphics driver stack now that
| there's mainline DRM support in the Linux
| 2.6.33 kernel and later releases that
| provides kernel mode-setting support and
| more. However, for those that have not yet
| made move to the Nouveau driver (or are
| running a *BSD or OpenSolaris where there
| is not yet the ported DRM) and are sticking
| it out with NVIDIA's rudimentary, feature-
| limited open-source driver, there is a new
| update out today. NVIDIA's Aaron Plattner
| has just declared the xf86-video-nv 2.1.17
| driver release.

University of Antwerp builds desktop supercomputer with 13 NVIDIA GPUs
,----[ Quote ]
| Therefore they had to search for an
| alternative, and once they learned about
| GPGPU computing the researchers build a
| 4000EUR desktop supercomputer with four
| NVIDIA GeForce 9800 GX2 dual-GPU graphics
| cards. The results were stunning, for this
| niche application the eight NVIDIA GPUs
| outperformed the universityâs three-year old
| 256-node supercomputer with AMD Opteron 250
| 2.4GHz processors. Besides the higher
| performance, other major advantages include
| the very low cost (4000EUR for FASTRA vs 3.5
| million euro for the real supercomputer) and
| much lower power consumption.
