I meant: "What about support for AMD cards". Sorry for the confusion.

In regards to the neural network framework in Mathematica 11.3, the reason why OpenCL isn't supported is that it hasn't been implemented in ML library/framework, MXNet. Please do reference the following Github issue:

MXNet Support for other Device Types, OpenCL AMD GPU

Both say they are current for my OS version macOS 11.13.2 (17C89). See pictures below:

Do you have the very latest Nvidia drivers installed? In System Preferences > CUDA does it say that a newer driver is available?

Thank you for the information Stefan, that seems to have updates the CUDA resources.

It is a rather painful process to get things stable and current, MMA does not offer clear steps and useful diagnostics.

Try doing PacletSiteUpdate/@PacletSites[] and then try again. You should get a paclet that has version "11.3.51".

Thank you very much!

Finally CUDA 9.1 with Visual Studio 2017 compiler supported :-)

But CUDACCompilers is still like in Mathematica 11.2 not funtional. But in SytemInformation Toolkit Version 4. is listed. Should this not be 9.1 ? And the Core Count says 320 while my GeForce GTX1060 with Max-Q Design has 1280 cores!

We have now released updated CUDALink paclets for Mathematica 11.3. Please run CUDAResourcesInstall[Update -> True] to get the new version. We apologize for the delay.

Hi on Windows 10 It seems that 11.3 is not finding the NVidea and 11.2 does. I have two Video cards on this Zbook (main Intel and second NVidea)

Sorry to say Sebastian, but you are really out of touch with what got delivered to your customers with 11.3 release.

Your team member (and customers) had to tell you that the CUDA paclet was downgraded with 11.3 release and myself and others will tell you that 11.3 causes macOS to reboot with current NVIDIA drivers and CUDA support under current macOS 10.3.3. What kind testing does Wolfram do? In the past I was offered a chance to at least try beta release, not for 11.3. WFT?

Under prior release of MMA I could run CUDA function on this machine, yes rather limited CUDA function but it ran.... now it crashes my Mac! I am not here to pay and debug your production product! If you don't test it DON'T release it as production code!

That's really bad!!!

What about support for NVidia cards for option TargetDevice->"GPU" in such things as Classify and other neural net-related functions?

That is already supported out-of-the-box in 11.3.0.

Given the long-time status of Mathematica as essentially platform-independent, it seems really constricting that only CUDA with NVidia is supported whereas OpenCL with AMD is not.

That has more to do with CUDA being the de-facto standard for most of the state-of-the-art neural network libraries (like MXNet), which Mathematica uses under the hood. If the libraries we use add support for OpenCL then we'd certainly investigate adding support from our end.

I must have mixed up my versions ... I was certain that I just tried this in 11.3 ("ReleaseID" -> "11.3.0.0 (5944637, 2018030701)") and it did not work. Now I tried it again and TargetDevice -> "GPU" seems to be working fine.

Do you support MacBook Pros with NVIDIA cards (from 2014 and before)?

For quite some time now (i.e. even in 11.2), TargetDevice -> "GPU" works for me only if I load CUDALink first, and then successfully evaluate CUDAQ[]. By "successfully" I mean that I'm lucky and it doesn't cause a crash. Often, the kernel just crashes after CUDAQ[].

In earlier versions (11.0? 11.1? I don't remember) both TargetDevice -> "GPU" and CUDALink used to work fine on this machine.

I have macOS 10.13, the NVIDIA web driver, and CUDA driver version 387.128.

We had hoped to have updated CUDALink paclets ready for 11.3 release but we ran into some technical issues that had to be resolved first. We plan to release updated CUDALink paclets with CUDA 9.1 support in the next few days, assuming the lingering issues can be ironed out in time.

As I run the exact same data science GPU code on identical hardware software configuration except for the change from Mathematica 11.2 to Mathematica 11.3 and see my neural network performance go from 295 seconds on 11.2 to 2038 seconds on 11.3.

When training the net, could you set the BatchSize and MaxTrainingRounds options to the same value in both versions, and then report the training time again? (we changed the heuristic for choosing a value of MaxTrainingRounds which sometimes uses more training rounds for extra accuracy. And: the inputs/s is a better indicator of speed than the total training time as it doesn't depend on MaxTrainingRounds). If there is still a speed difference, could you give information about the GPU you are using, the output of $Version and if possible the training script to reproduce this training?

And then I see that Mathematica 11.3 still does not support current XCode LLVM/GCC compiler or NVIDIA for CUDA tools

I am not sure exactly what you mean by this. Could you expand a bit about which functionality you are referring to that doesn't support "current XCode LLVM/GCC compiler or NVIDIA"?
