Hello,
I'm trying to run beignet from Wolfram Mathematica 10.0.1, I have
beignet 0.9.2, Fedora 20 x86_64, kernel 3.16.3, i5-3230M.
First, there is an issue which is probably to be blamed on Mathematica
(you need to manually load /usr/lib64/beignet/libcl.so with
LibraryLoad), I suppose that Mathematica doesn't know about the icd system.
Anyway, after that, this test program
src = "__kernel void myKernel( __global mint * global0Id, __global
mint * global1Id, mint width, mint height) {
int xIndex = get_global_id(0);
int yIndex = get_global_id(1);
int index = xIndex + yIndex*width;
if (xIndex < width && yIndex < height) {
global0Id[index] = get_local_id(0);
global1Id[index] = get_local_id(1);
}
}";
which is suggested in the examples of the Mathematica implementation
(http://reference.wolfram.com/language/OpenCLLink/tutorial/Programming.html)
produces all zeroes. If instead the pocl driver is loaded, the kernel is
executed correctly. Also I could run the LuxMark benchmarks (even though
on some tests I see yellow spots that I believe are glitches).
I am sorry if the question is a bit vague, but I don't know much about
OpenCL and I indeed wanted to start learning while using Mathematica,
which is a tool that I already need for other reasons.
Lorenzo
