Speeding Up The Linux Kernel With Your GPU

Filed under

Hardware

Sponsored in part by NVIDIA, at the University of Utah they are exploring speeding up the Linux kernel by using GPU acceleration. Rather than just allowing user-space applications to utilize the immense power offered by modern graphics processors, they are looking to speed up parts of the Linux kernel by running it directly on the GPU.

From the project page: "The idea behind KGPU is to treat the GPU as a computing co-processor for the operating system, enabling data-parallel computation inside the Linux kernel. This allows us to use SIMD (or SIMT in CUDA) style code to accelerate Linux kernel functionality, and to bring new functionality formerly considered too compute intensive into the kernel. Simply put, KGPU enables vector computing for the kernel."

Additionally, "it makes the Linux kernel really parallelized: it is not only processing multiple requests concurrently, but can also partition a single large requested computation into tiles and spread them across the large number of cores on a GPU."

Giving Linux and LibreOffice a Try for Your Home Office

Running your home office on a tight budget? There's a way to get all of your software—operating system (OS), productivity suite, scores of applications—completely free. It'll cost you, but not in the way you might think. This life-changing alternative is Linux, which gives you more flexibility, more have-it-your-way customization, and more control than Windows or OS X users could ever dream of. I caution that it'll cost you because it's decidedly not for everyone. While it's far friendlier today than it was a year or even six months ago, Linux still requires you to invest, nay, enjoy some time spent setting up and tinkering with your PC.
