I would like to ask for WU's for Intel GPU's. Not as plentiful as the big guys but Dell makes a lot of Intel based systems that contain GPU's that crunch other projects quite nicely.

Thanks

If this project had people who knew how to adapt it to run on intel GPU's, Im sure they would love for them to do so. Unfortunately, as far as I am aware there are not a lot of people currently on the admin team for this project, and they are already very busy. In short, I would love to be able to run this on an intel GPU or an AMD GPU or any other architecture that ever existed, but the limiting factor is the amount of time available to the developers.

That being said, it WOULD be really cool to see an intel GPU or an AMD GPU capable application.

I also would like to recommend adding Intel GPUs...with the addition of separate Intel video cards, the amount of Intel GPUs available for crunching is on the rise.

the Asteroids code makes heavy use of FP64 double precision and Intel GPUs lack hardware FP64 support.

So it likely won’t happen until Intel starts making GPUs with FP64.

Slight addendum.

Intel iGPUs only support FP64 on 6th/7th/8th/9th gen. Devices before or after this won’t work. And not until they get hardware FP64 in future generations of their dedicated GPUs (if they do), current gen Arc cards still lack FP64 at all.

https://community.intel.com/t5/Graphics/What-processors-have-an-internal-Gen11-GPU-with-FP64-double/m-p/691214

There also exists a driver workaround for Linux systems to emulate FP64 on their newer Linux driver for the newer devices that don’t natively support FP64, but the same thing is not supported in Windows, and it’s painfully slow anyway.

In Linux the support of Intel is improving at a fairly good rate..... Some reading: https://www.phoronix.com/news/Intel-Xe-Submission-Linux-6.8 https://www.phoronix.com/news/Intel-CR-23.30.26918.9

Lack of hardware FP64 is the biggest issue with Asteroids. FP64 is required here.

I have seen a reference to FP64 in the upcoming Xe driver for Linux---I'll try to find the information & post it here.

I have found these references:
1. https://github.com/intel/compute-runtime/blob/master/opencl/doc/FAQ.md#feature-double-precision-emulation-fp64
2. https://community.intel.com/t5/GPU-Compute-Software/Iris-Xe-Graphics-can-t-compute-double-precision-floating-point/td-p/1281976
3. https://foldingforum.org/viewtopic.php?t=38527 (as this is an older posting, I expect improvements on this in the last year or so...)

As the Intel compute-runtime information notes: This feature is only available in Linux.

I have seen other references to FP64 in developer notes but have not been able to pin those references down as of yet....I will continue to look. I'm the main poster for Intel Arc & Xe driver information on the EndeavourOS forum.

I’m not sure the value in reposting information that I’ve already linked to and mentioned.

Intel GPUs at this time largely don’t support FP64. And the workarounds that do exist are very slow and only work in select few environments.

This project relies heavily on FP64 calculations. Intel GPU is not viable at this time. That could change if future generations of GPUs have hardware FP64 support, but for right now it’s basically a non-starter.
