[Beignet] *** SPAM LEVEL 4.053 *** compiler_local_memory_barrier_wg64 fails in current HEAD

[Xing, Homer]

I can reproduce this.
I ran this case twenty-five times, and got two times of failure, twenty-three times of success.
After changing to CLK_GLOBAL_MEM_FENCE, I ran this case fifty times, and fifty times of success.

I can't reproduce this on my machine. But I do remember it really happened one or two times about one month ago.
Does it reproduce easily on your machine? If it is, could you try to change the local memory barrier to global memory Barrier and see what's the difference.

I mean change the CLK_LOCAL_MEM_FENCE to CLK_GLOBAL_MEM_FENCE at kernels/compiler_local_memory_barrier_wg64.cl

Thanks.
