[G3D] KGPU: GPU Acceleration for Linux Kernel

post #1 of 16
Thread Starter 

Quote:
KGPU is a new project that aims at using the GPU as a co-processor for the Linux kernel.
This is a new step in the use of the GPU. Many applications are already accelerated by the GPU thanks to real time shader languages or GPGPU APIs like CUDA / OpenCL. Even malwares take advantage of GPUs for implementing unpacking and runtime polymorphism to elude virus scanners.

Now GPUs can be use to speed up the kernel of operating systems. KGPU is a framework for calling GPU code from the Linux kernel. Here are some kernel tasks than can be accelerated by the GPU:
  • network packet processing
  • in-kernel cryptography (IPSec, encrypted filesystems)
  • pattern matching (the GPU can accelerate regular expression matching, with speedups of up to 48x reported over CPU implementations)
  • basic algorithms: sort, search and graph analysis
KGPU is implemented using NVIDIA CUDA. To demonstrate the feasibility of KGPU, the AES encryption algorithm has been implemented as a service on the GPU for the Linux crypto subsystem. When the size of data is larger than 8KB, the GPU (a GTX 480) outperforms the CPU (Core i7-930).

Windows needs this now.

this is awesome

can we get an apache httpd that will run on a GPU at some point? think of the performance with multiple GPUs, you could have a bucket listen on each GPU and load balance with nginx using the cpu

Can the Linux kernal use this simultaneously with 3D accelerated desktop or is this more for some server running strictly CLI?

Yes it's called direct compute and it's why windows 7 is lousy because the gpu scheduler used to be in the video driver. And now it's in the operating system.

This.

Why the hell did they go with CUDA? What about OpenCL?
I don't see this being accepted into the mainline kernel in it's current state
