Staxrip: KNLMeansCL/QTGMC for Xeon users (error 126)

[vonH]

Describe the niche issue
The included KNLMeansCL is not supported on Xeon platforms without GPUs, despite an OpenCL runtime for CPU existing.

Expected behaviour
I expected Staxrip to have noted this in documentation, or for the runtime to be included (I know this is a very niche scenario).

How to reproduce the issue
Try using QTGMC on a Xeon without a dGPU, or any CPU without an iGPU (tested on old consumer AMD CPU without iGPU and GPU and found the same issue).

Provide information
This is more of a record for those who have the same issue, and a fix for it. If you find Staxrip produces a '126' error when trying to use 'QTGMC with Repair', and have a Xeon, you need to download the Intel® CPU Runtime for OpenCL™ Applications for Windows OS

1. Older versions of KNLMeansCL designed for CPU-only will not work.
2. You will need to create an account on Intel's website.

Windows 64bit:

Linux 64bit (for emulation):

You may need to use an older binary as well. The specific version can be found here:

https://github.com/Khanattila/KNLMeansCL/releases/tag/v0.6.11

Replace the x64 .dll from

\Staxrip\Apps\Plugins\Dual\KNLMeansCL

with the one from the zip.

You may also need a new runtime:

I have tested and confirmed this resolves the issue with Staxrip and, I imagine, similar software that using QTGMC.

Notes
Please feel free to mark this as Resolved and close. I would post and close, but interested if any of the team have anything to add.

@vonH may I suggest you copy this information (as you are the author of the first post) to the Wiki section and close this thread, please ?

@vonH I think you misunderstood me, I was asking you to copy this to the wiki, so we can close this non-bug thread.
Well I'll do it myself. Thanks for not bothering.
@Dendraspis or Vonh can you close this thread.
I have put on the wiki information with the corrected links as they should be in a new wiki page.
