Ideas for Google Summer of Code

Hello All, I am a PhD student who has been working with CUDA for the GPU and also gcc for Cell BE for about a year now. (By work I mean developing applications). I am looking to bring GCC closer to being able to support OpenCL as a Google Summer of Code. Here are some of my ideas: 1. Make an NV

Hi All, Thanks for the feedback. As far as the NVIDIA ISA details, I have the pdf that describes it. In the CUDA toolkit, available on NVIDIA's website there is a pdf named ptx_isa_1.3.pdf under the doc directory. (Get it from here http://www.nvidia.com/object/cuda_get.html). So we can do Intel

Joe Buck, You have to choose an operating system and then a table appears below it to download the CUDA toolkit. Phil On Mon, Mar 30, 2009 at 1:32 PM, Joe Buck wrote: > On Mon, Mar 30, 2009 at 10:10:24AM -0700, phil++ wrote: >> Hi All, >> >> Thanks for the feedback.  As far as the NVIDIA ISA

Re: Ideas for Google Summer of Code

Paolo, Thanks for the feedback, I am not very experienced in compilers so it is hard to judge how long a task will take... By sharing I meant sharing of code between NVIDIA and GCC. It probably won't happen I guess. Here is my proposal for an OpenCL runtime with a target runtime as well. If yo
