Hi Soufiane,
I am working on OpenCL for google summer of code. I just emailled my
mentor asking about what the rules of collaboration are while I am
being paid under gsoc. (It is a little fuzzy on the website: Q: Can a
group apply for and work on a single proposal? A: No, only an
individual may work on a given project. Of course, students should
feel free to collaborate with others to accomplish their project
goals.)
You can certainly do work on your own and I would love to work with you.
I will let you know what my mentor says.
Sincerely,
Phil

Hello Phil,
I am happy to work with you, just tell me which parser do you use?
do you convert your parsed OpenCL grammar to ATI IL or Stream?
can i start from where you are or should i do all the work from scratch!

Hi Soufiane,
My gsoc project is not making an OpenCL C compiler, but instead the
supporting infrastructure. I have made rough draft functions that
support clCreateContext, clCreateCommandQueue, clCreateMemoryObject,
clCreateProgramWithBinaries, clCreateKernel, clEnqueueNDRangeKernel
and clEnqueueBufferRead. Without an OpenCL C compiler, I get use
clCreateProgramWithBinaries to load compiled code into the runtime. So
far this works to load dynamic link libraries on the cpu (without
knowing the number of kernel arguments at compile time). I am making
a structure where there are various drivers for all the different
devices and I am focusing on CPU and Cell. So if you wanted to make a
device driver to load and execute the ATI binaries, that would be a
big help (as long as it is okay with google).
We use git for this project. There is barely any documentation right
now as I am developing things still (and things can change a little if
you need info for the driver). The code is in github:
http://github.com/pcpratts/gcc_opencl/tree/master
The code I was talking about is in cl/devices/cpu/generic/driver.c
To run the code you will need the dependencies in the NOTES file.
Also you will need to put the output of
# lshw -xml > lshw_output.xml
in the root folder of the project.
Phil
