topic Dear Matthias, in OpenCL* for CPU

OpenCL for the MIC does is missing dependencies?

Hi,

it appears my MPSS is too new to install OpenCL for the MIC? This is what rpm tells me:

error: Failed dependencies:
intel-mic >= 2.1.4346 is needed by opencl-1.2-intel-mic-1:3.1.1.11385-1.x86_64

The rpm names of the MPSS packages have changed, though. What is the plan here?

Thanks Matthias for your

Thanks Matthias for your question.

This is a known limitation, which is documented in the release notes. We plan to fix it in the next update release.

Until then, you may switch back to MPSS ver 2.1. (Which the OpenCL XE R2 is tested with)

Another option:

While this version of OpenCL was not tested with MPSS 3.1, you may try it out by bypassing the RPM dependency by adding the following RPM option: –nodeps (sudo rpm -i --nodeps *.rpm)

Arik

OK, so the question is: how

OK, so the question is: how long do I have to wait for a new OpenCL release that works with 3.1?

I installed with --nodeps. Looks good after a first test:

Dear Matthias,

Currently, we cannot share the release date. But we will release a solution in the near future.

Thanks,
