![]() This is about the fact that Facebook Inc. No sane AI researcher is using a Mac for any serious DL work. Today you should buy an Nvidia GPU and keep your sanity.Īnd before you say who cares about your Macbook issues - it’s not about that. So, basically at some point stuff will work out. No budget? This leads us back to the wonderful comment and meme from above in the Tensorflow GH issue. What I don’t get is why Google decided to not support OpenCL officially from the start. At this point I have to congratulate Nvidia for creating not only a great technology but an amazing (in a bad way) technical lock-in to its GPU platform. HIP source code looks similar to CUDA but compiled HIP code can run on both CUDA and AMD based GPUs through the HCC compiler.ROCm created a CUDA porting tool called HIP, which can scan CUDA source code and convert it to HIP source code.HCC supports the direct generation of the native Radeon GPU instruction set ROCm includes the HCC C/C++ compiler based on LLVM.Looking into this I found the following infos: PyTorch AMD runs on top of the Radeon Open Compute Stack (ROCm)…”Įnter ROCm (RadeonOpenCompute) - an open source platform for HPC and “UltraScale” Computing. ![]() “Disclaimer: PyTorch AMD is still in development, so full test coverage isn’t provided just yet. Generic OpenCL support has strictly worse performance than using CUDA/HIP/MKLDNN where appropriate.ĭigging further, I found this issue from : Intel is moving it’s speed and optimization value into MKLDNN. We officially are not planning any OpenCL work because:ĪMD itself seems to be moving towards HIP / GPUOpen which has a CUDA transpiler (and they’ve done some work on transpiling Torch’s backend). Here is a statement from a contributor from the Facebook AI Research team: This ticket is way more sane than the other one. Open since: (actually it’s closed now with a “needs discussion” label) This screenshot of the first 2 entries in the GH ticket describes the status quo. Tensorflow locked the issue as “too heated” and limited conversation to collaborators on. (It’s issue #22 we are currently at #28961) Here is the state of the OpenCL implementation of the 2 most popular deep learning libraries: Now back to CUDA and TensorFlow and all other buzzwords. running stuff on GPUs as a primary computational unit instead of the CPU, in case your friends ask. And to drop-in some knowledge here: all of this kind of runs under the banner of “General Purpose Computing on Graphics Processing Units” (GPGPU) i.e. Ironically, Nvidia CUDA-based GPUs can run OpenCL but apparently not as efficiently as AMD cards according to this article. It is basically what AMD uses in their GPUs for GPU acceleration (CUDA is a proprietary technology from Nvidia!). OpenCL™ (Open Computing Language) is the open, royalty-free standard for cross-platform, parallel programming of diverse processors found in personal computers, servers, mobile devices and embedded platforms. Namely that popular libraries for training ANNs like TensorFlow and PyTorch do not officially support OpenCL. But why can’t I run this on my fancy $ 7k Mid-2019 Macbook with 8 cores and HBMI2-based Vega 20 GPU. The idea is to run these computationally expensive tasks on the GPU, which has thousands of optimized GPU cores that are just infinitely better for such tasks compared to CPUs (sorry Intel). What you need to know is that this is the underlying core technology that is being used - amongst other things - to accelerate the training of artificial neural networks (ANNs). With CUDA, developers are able to dramatically speed up computing applications by harnessing the power of GPUs. Why is it disappointing? Because you get the latest and greatest Vega GPU that of course does not use CUDA.ĬUDA® is a parallel computing platform and programming model developed by NVIDIA for general computing on graphical processing units (GPUs). If you are a Deep Learning researcher or afficionando and you happen to love using Macs privately or professionally, every year you get the latest and greatest disappointing AMD upgrade for your GPU.
