Beignet not detect Intel GPU

I'm trying to run `hashcat` on GPU. However it outputs:

hashcat (v5.1.0) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

No devices found/left.

I tried installing `intel-opencl` and `intel-compute-runtime` as well, but they fail (with a somewhat-different error)

Re: Beignet not detect Intel GPU

Does your system have more than one GPU?

Re: Beignet not detect Intel GPU

I've got the same graphics as you do but I can't find any evidence that our stuff can run opencl to off load compute to the gpu.

https://software.intel.com/en-us/intel-opencl

I could certainly be wrong tho.

Edit: this may help

https://01.org/compute-runtime

Edit1: It seems as though our chipset cannot use opencl for bitcoin mining either.

Edit2: After reading about the architecture I think the point is moot anyway, the gma x4500 HD(?) graphics use system memory so there wouldn't really be anything to off-load to
