Can I run Cuda or OpenCl on Intel processor graphics I7 (3rd or 4rd generation)

Question

I'm developing on SBC (which have Intel I7 3ed or 4ed, and doesn't have external GPU) I'm using linux. I want to take the advantage of Intel processor graphics . I thought to learn developing with Cuda or OpenCl. I read some old posts (several years ago) (and I'm not sure there is a better technology now):

Can i run CUDA on Intel

GPU Programming, CUDA or OpenCL

1. Can I run cuda code on Intel processor graphics ?
2. Can I run OpenCl code on Intel processor graphics ?
3. If I can run Cuda & OpenCl code on Intel processor graphics, which is better ?

Solution 1

As @Robert Crovella said you cannot run CUDA on Intel GPU/CPU. Where it comes to OpenCL you have few choices:

1. Intel OpenCL Driver for Intel GPU and CPU
2. Open Source Beignet for Intel GPU
3. AMD APP SDK which can be run on Intel CPU

I cannot say which one will be best for Intel GPU on Linux. I think Beignet was first to support Intel GPU then official Intel drivers appeared. For Intel CPU on Linux I use AMD APP SDK.

Solution 2

You can now :-) Using: coriander, which is an NVIDIA® CUDA™ compiler for OpenCL 1.2 GPUs (full disclosure: I'm the author)

Just to be sure, all of the 3 run on the gpu which locates on the Intel processor ?

No, only the first 2 (Intel official and Beignet). AMD APP SDK on CPU only.

(1) and (3) are identical; they both use the OpenCL API, just using a different SDK package. The performance will be identical because the underlying Intel integrated graphics OpenCL GPU driver is the same.

[doqtor]

@Dithermaster Yes they are identical in a sense that you can run both on Intel GPU provided you have installed GPU driver. But if (1) is installed then (3) is not really needed - (1) has to be installed with the whole Intel Media Server Studio which already contains OpenCL SDK. I mentioned (3) to say that installed alone it is capable of running OpenCL on Intel CPU.

[Dithermaster]

Sure, but he was asking about Intel GPU, not CPU.

[Z boson]

You answer is misleading. Beignet is only for the GPU.

[Anderson Green]

Is the Coriander compiler still being maintained? I found a more recent compiler (HIP) that was developed for the same purpose.

[Hugh Perkins]

HIP is AMD-specific. Coriander aims to be portable across OpenCL 1.2 devices.

for lazy folks here is the link to the github repo of the intel openCL driver with installation instructions: github.com/intel/compute-runtime#installation-options

beignet seems no longer supported: last release in 2017
