Geoffroy,
I tried OpenCLIPP. After some fixes in OpenCLIPP part, it works well with
beignet.
gongzg@ivb-gt2-rev4:~/git/fdo/OpenCLIPP-master/Test-OpenCLIPP$
LD_LIBRARY_PATH=`pwd`/.. ./Test-OpenCLIPP
Using OpenCL device : Intel(R) HD Graphics IvyBridge GT2
Success
And all the benchmark could finish successfully.
It seems that the OpenCLIPP is mainly for windows platform, part of the fix is
to
fix those obvious broken directories name on linux platform, such as:
diff -ur OpenCLIPP-master/Bench/src/config.h
../OpenCLIPP-master/Bench/src/config.h

-#define CL_FILES_PATH "D:/OpenCLIPP/cl-files/"

Another major fix is like below. Per opencl spec, constant buffer could only be
declared in a function. It could only be declared in program
scope.

If you want to get the whole patch for OpenCLIPP, please let me know.
Thanks,
