QUESTION
In my understanding, VkPhysicalDevice represents an implementation of Vulkan, which could be represented as a GPU and its drivers. We are supposed to record commands with VkCommandBuffers and send them through queues to, potentially, multithread the work we send to the gpu. That is why I understand the fact there can be multiple queues. I understand as well that QueueFamilies groups queues depending on the features they can do (the extensions available for them e.g. presentation, as well as graphics computations, transfer, etc).
However, if a GPU is able to do Graphics work, why are there queues unable to do so? I heard that using queues with less features could be faster, but why? What is a queue concretely? Is it only tied to vulkan implementation? Or is it related to hardware specific things?
I just don't understand why queues with different features exist, and even after searching through the Vulkan doc, StackOverflow, vulkan-tutorial and vkguide, the only thing I found was "Queues in Vulkan are an “execution port” for GPUs.", which I don't really understand and on which I can't find anything on google.
Thank you in advance for your help!
...ANSWER
Answered 2022-Apr-03 at 21:56A queue is a thing that consumes and executes commands, such that each queue (theoretically) executes separately from every other queue. You can think of a queue as a mouth, with commands as food.
Queues within a queue family typically execute commands using the same underlying hardware to process them. This would be like a creature with multiple mouths but all of them connect to the same digestive tract. How much food they can eat is separate from how much food they can digest. Food eaten by one mouth may have to wait for food previously eaten by another to pass through the digestive tract.
Queues from different families may (or may not) have distinct underlying execution hardware. This would be like a creature with multiple mouths and multiple digestive tracts. If a mouth eats, that food need not wait for food from a different mouth to digest.
Of course, distinct underlying execution hardware is typically distinct for a reason. Several GPUs have specialized DMA hardware for doing copies to/from device-local memory. Such hardware will typically expose a queue family that only allows transfer operations, and those transfer operations may be restricted in their byte alignment compared to transfers done on graphics-capable queues.
Note that these are general rules. Sometimes queues within a family do execute on different hardware, and sometimes queues between families use much of the same hardware. The API and implementations don't always make this clear, so you may have to benchmark different circumstances.
QUESTION
- Does OpenCL local memory really exist on Mali/Adreno GPU or they only exist in some special mobile phones?
- If they exist, in which case should we use local memory, such as GEMM/Conv or other cl kernel?
ANSWER
Answered 2022-Mar-24 at 15:27Interesting question. OpenCL defines a number of conceptual memories including local memory, constant memory, global memory, and private memory. And physically as you know, the hardware implementation of these memories is hardware dependent. For instance, some may emulate local memory using cache or system memory instead of having physical memory.
AFAIK, ARM Mali GPU does not have local memory, whereas Qualcomm Adreno GPU does have local memory.
For instance below table shows the definition of each memory in OpenCL and their relative latency and physical locations in Adreno GPU cited from OpenCL Optimization and Best Practices for Qualcomm Adreno GPUs∗
Answer updated:
as commented by SK-logic below, Mali6xx have a local memory (shared with cache).

QUESTION
I'm trying to setup a Google Kubernetes Engine cluster with GPU's in the nodes loosely following these instructions, because I'm programmatically deploying using the Python client.
For some reason I can create a cluster with a NodePool that contains GPU's
...But, the nodes in the NodePool don't have access to those GPUs.
I've already installed the NVIDIA DaemonSet with this yaml file: https://raw.githubusercontent.com/GoogleCloudPlatform/container-engine-accelerators/master/nvidia-driver-installer/cos/daemonset-preloaded.yaml
You can see that it's there in this image:
For some reason those 2 lines always seem to be in status "ContainerCreating" and "PodInitializing". They never flip green to status = "Running". How can I get the GPU's in the NodePool to become available in the node(s)?
Update:Based on comments I ran the following commands on the 2 NVIDIA pods; kubectl describe pod POD_NAME --namespace kube-system.
To do this I opened the UI KUBECTL command terminal on the node. Then I ran the following commands:
gcloud container clusters get-credentials CLUSTER-NAME --zone ZONE --project PROJECT-NAME
Then, I called kubectl describe pod nvidia-gpu-device-plugin-UID --namespace kube-system and got this output:
ANSWER
Answered 2022-Mar-03 at 08:30According the docker image that the container is trying to pull (gke-nvidia-installer:fixed), it looks like you're trying use Ubuntu daemonset instead of cos.
You should run kubectl apply -f https://raw.githubusercontent.com/GoogleCloudPlatform/container-engine-accelerators/master/nvidia-driver-installer/cos/daemonset-preloaded.yaml
This will apply the right daemonset for your cos node pool, as stated here.
In addition, please verify your node pool has the https://www.googleapis.com/auth/devstorage.read_only scope which is needed to pull the image. You can should see it in your node pool page in GCP Console, under Security -> Access scopes (The relevant service is Storage).

I've run into an issue while attempting to use SSBOs as follows:
...ANSWER
Answered 2022-Feb-10 at 13:25GLSL structs and C++ structs have different rules on alignment. For structs, the spec states:
If the member is a structure, the base alignment of the structure is N, where N is the largest base alignment value of any of its members, and rounded up to the base alignment of a vec4. The individual members of this substructure are then assigned offsets by applying this set of rules recursively, where the base offset of the first member of the sub-structure is equal to the aligned offset of the structure. The structure may have padding at the end; the base offset of the member following the sub-structure is rounded up to the next multiple of the base alignment of the structure.
Let's analyze the struct:

...ANSWER
Answered 2022-Jan-07 at 11:08Gradient tape triggers automatic differentiation which requires tracking gradients on all your weights and activations. Autodiff requires multiple more memory. This is normal. You'll have to manually tune your batch size until you find one that works, then tune your LR. Usually, the tune just means guess & check or grid search. (I am working on a product to do all of that for you but I'm not here to plug it).
QUESTION
I've installed Windows 10 21H2 on both my desktop (AMD 5950X system with RTX3080) and my laptop (Dell XPS 9560 with i7-7700HQ and GTX1050) following the instructions on https://docs.nvidia.com/cuda/wsl-user-guide/index.html:
- Install CUDA-capable driver in Windows
- Update WSL2 kernel in PowerShell:
wsl --update - Install CUDA toolkit in Ubuntu 20.04 in WSL2 (Note that you don't install a CUDA driver in WSL2, the instructions explicitly tell that the CUDA driver should not be installed.):
ANSWER
Answered 2021-Nov-18 at 19:20Turns out that Windows 10 Update Assistant incorrectly reported it upgraded my OS to 21H2 on my laptop.
Checking Windows version by running winver reports that my OS is still 21H1.
Of course CUDA in WSL2 will not work in Windows 10 without 21H2.
After successfully installing 21H2 I can confirm CUDA works with WSL2 even for laptops with Optimus NVIDIA cards.
QUESTION
I tried to train a model using PyTorch on my Macbook pro. It uses the new generation apple M1 CPU. However, PyTorch couldn't recognize my GPUs.
...ANSWER
Answered 2021-Nov-18 at 03:08It looks like PyTorch support for the M1 GPU is in the works, but is not yet complete.
From @soumith on GitHub:
So, here's an update. We plan to get the M1 GPU supported. @albanD, @ezyang and a few core-devs have been looking into it. I can't confirm/deny the involvement of any other folks right now.
So, what we have so far is that we had a prototype that was just about okay. We took the wrong approach (more graph-matching-ish), and the user-experience wasn't great -- some operations were really fast, some were really slow, there wasn't a smooth experience overall. One had to guess-work which of their workflows would be fast.
So, we're completely re-writing it using a new approach, which I think is a lot closer to your good ole PyTorch, but it is going to take some time. I don't think we're going to hit a public alpha in the next ~4 months.
We will open up development of this backend as soon as we can.
That post: https://github.com/pytorch/pytorch/issues/47702#issuecomment-965625139
TL;DR: a public beta is at least 4 months out.

Install gpu-jupyter
A computer with an NVIDIA GPU is required.
Install Docker version 1.10.0+ and Docker Compose version 1.28.0+.
Get access to your GPU via CUDA drivers within Docker containers. You can be sure that you can access your GPU within Docker, if the command docker run --gpus all nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04 nvidia-smi returns a result similar to this one: Mon Apr 26 13:59:53 2021 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 465.19.01 Driver Version: 465.19.01 CUDA Version: 11.3 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

The CUDA toolkit is not required on the host system, as it will be installed within the Docker containers using NVIDIA-docker. It is also important to keep your installed CUDA version in mind, when you pull images. You can't run images based on nvidia/cuda:11.2 if you have only CUDA version 10.1 installed. Check your host's CUDA-version with nvcc --version and update to at least the same version you want to pull.
Pull and run the image. This can last some hours, as a whole data-science environment will be downloaded: cd your-working-directory docker run --gpus all -d -it -p 8848:8888 -v $(pwd)/data:/home/jovyan/work -e GRANT_SUDO=yes -e JUPYTER_ENABLE_LAB=yes --user root cschranz/gpu-jupyter:v1.4_cuda-11.0_ubuntu-20.04_python-only This starts an instance of GPU-Jupyter with the tag v1.4_cuda-11.0_ubuntu-20.04_python-only at http://localhost:8848 (port 8848). The default password is gpu-jupyter (previously asdf) which should be changed as described below. Furthermore, data within the host's data directory is shared with the container. The following images of GPU-Jupyter are available on Dockerhub: v1.4_cuda-11.0_ubuntu-20.04 (full image) v1.4_cuda-11.0_ubuntu-20.04_python-only (only with a python interpreter and without Julia and R) v1.4_cuda-11.0_ubuntu-20.04_slim (only with a python interpreter and without additional packages) v1.4_cuda-11.0_ubuntu-18.04 (full image) v1.4_cuda-11.0_ubuntu-18.04_python-only (only with a python interpreter and without Julia and R) v1.4_cuda-11.0_ubuntu-18.04_slim (only with a python interpreter and without additional packages) v1.4_cuda-10.1_ubuntu-18.04 (full image) v1.4_cuda-10.1_ubuntu-18.04_python-only (only with a python interpreter and without Julia and R) v1.4_cuda-10.1_ubuntu-18.04_slim (only with a python interpreter and without additional packages) The version, e.g. v1.4, specifies a certain commit of the underlying docker-stacks. The Cuda version, e.g. cuda-11.0, has to match the host's driver version and must be supported by the gpu-libraries. These and older versions of GPU-Jupyter are listed on Dockerhub.
This is the preferred option if one has a different GPU-architecture or one wants to customize the pre-installed libraries. For the second point, the Dockerfiles in src/ are intended to be modified. In order the select a custom base image alter src/Dockerfile.header, to install specific GPU-related libraries modify src/Dockerfile.gpulibs and to add specific libraries append the in src/Dockerfile.usefulpackages. After the modification, it is necessary to re-generate the Dockerfile in .build. As soon as you have access to your GPU within Docker containers (make sure the command docker run --gpus all nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04 nvidia-smi shows your GPU statistics), you can generate the Dockerfile, build and run it. The following commands will start GPU-Jupyter on localhost:8848 with the default password gpu-jupyter (previously asdf). This starts a container WITH GPU support, a shared local data volume data and some other configurations like root permissions which are necessary to install packages within the container. For more configurations, scroll down to Configuration of the Dockerfile-Generation.
This step requires a running Docker Swarm on a cluster or at least on this node. In order to register custom images in a local Docker Swarm cluster, a registry instance must be deployed in advance. Note that the we are using the port 5001, as many services use the default port 5000. This should output {}. \. Afterwards, check if the registry service is available using docker service ls.
