When I run "./utest_run", I get 18 errors,
Those tests use the __local memory space, which does not work on Haswell
without a kernel patch:

When I run any OpenCL programs, I need root privilege
You shouldn't; you may have accidentally built beignet without X
support. Run
sudo apt-get install cmake pkg-config python ocl-icd-dev
ocl-icd-opencl-dev libdrm-dev libxfixes-dev libxext-dev llvm-3.5-dev
clang-3.5 libclang-3.5-dev libtinfo-dev libedit-dev zlib1g-dev
then recompile beignet.
Aiming at a self-defined structure, used by host and kernel, do I need to align
the bytes? If so, how many bytes should I need to align?
