"Nothing works on Haswell-ULT" is a known bug, fixed by http://cgit.freedesktop.org/beignet/commit/?id=83f8739b6fc4893fac60145326052ccb5cf653dc
(Should that also be applied to the 1.0 branch?)

If you prefer not to recompile beignet, a workaround is:
sudo echo 0 > /sys/module/i915/parameters/enable_cmd_parser

Note that even with this fixed, the __local memory space will not work; see https://01.org/zh/beignet/downloads/linux-kernel-patch-hsw-support if you need that.
