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).
QUESTION
When using an OpenACC "#pragma acc routine worker
"-routine, that contains multiple loops of vector (and worker) level parallelism, how do vector_length
and num_workers
work?
I played around with some code (see below) and stumbled upon a few things:
- Setting the vector length of these loops is seriously confusing me. Using the
vector_length(#)
clause on the outerparallel
region seems to work weirdly, when comparing run times. When I increase the vector length to huge numbers, say e.g.4096
, the run time actually gets smaller. In my understanding, a huge amount of threads should lie dormant when there are only as many as10
iterations in the vector loop. Am I doing something wrong here? - I noticed that the output weirdly depends on the number of workers in
foo()
. If it is16
or smaller, the output is "correct". If it is32
and even much larger, the loops inside the worker routine somehow get executed twice. What am I missing here?
Can someone give me a hand with the OpenACC routine
clause? Many thanks in advance.
Here is the example code:
...ANSWER
Answered 2022-Feb-15 at 19:35The exact mapping of workers and vectors will depend on the target device and implementation. Specifically when using NVHPC targeting NVIDIA GPUs, a "gang" maps to a CUDA Block, "worker" maps the the y dimension of a thread block, and "vector" to the x-dimension. The value used in "num_workers" or "vector_length" may be reduced given the constrains of the target. CUDA Blocks can contain up to a maximum 1024 threads so the "4096" value will be reduced to what is allowed by the hardware. Secondly, in order to support vector reductions in device routines, a maximum vector_length can be 32. In other words, you're "4096" value is actually "32" due to these constraints.
Note to see the max thread block size on your device, run the "nvaccelinfo" utility and look for the "Maximum Threads per Block" and "Maximum Block Dimensions" fields. Also, setting the environment variable "NV_ACC_TIME=1" will have the runtime produce some basic profiling information, including the actual number of blocks and thread block size used during the run.
In my understanding, a huge amount of threads should lie dormant when there are only as many as 10 iterations in the vector loop.
CUDA threads are grouped into a "warp" of 32 threads where all threads of a warp execute the same instructions concurrently (aka SIMT or single instruction multiple threads). Hence even though only 10 threads are doing useful work, the remaining 12 are not dormant. Plus they still take resources such as registers so adding too many threads for loops with lower trip counts, may actually hurt performance.
In this case setting the vector length to 1 is most likey the best case since the warp can now be comprised of the y-dimension threads. Setting it to 2, will cause a full 32 thread warp in the x-dimension, but only 2 doing useful work.
As to why some combinations give incorrect results, I didn't investigate. Routine worker, especially with reductions, is rarely used so it's possible we have some type of code gen issue, like an off-by one error in the reduction, at these irregular schedule sizes. I'll look into this later and determine if I need to file an issue report.
For #2, How you're determining it's getting run twice? Is just this based on the runtime?

After heavy simulation that crashes my GPU, terminating the program and rebooting my computer, I cannot call any cuda api that runs correctly before rebooting. nvidia-smi works well. In my Ubuntu 20.04 computer, the CUDA11.6 and nvidia-driver 510.47.03 are installed.
The minimum codes for getting error in my computer are followings,

Answered 2022-Feb-11 at 14:25looks like you trashed something (driver or cuda runtime) and you are not able to call any function related to cuda.
in my humble experience, I usually get these errors when my kernels runs for too long on a Windows machine and the Windows Display Driver Manager reset my GPU while i'm running the kernel.
Maybe you are experiencing some similiar issues on linux.
To fix this, have you tried to reset your GPU using the following bash command line ?
QUESTION
I'm running a google cloud composer GKE cluster. I have a default node pool of 3 normal CPU nodes and one nodepool with a GPU node. The GPU nodepool has autoscaling activated.
I want to run a script inside a docker container on that GPU node.
For the GPU operating system I decided to go with cos_containerd instead of ubuntu.
I've followed https://cloud.google.com/kubernetes-engine/docs/how-to/gpus and ran this line:
...ANSWER
Answered 2022-Feb-02 at 18:17Can i do that with kubectl apply ? Ideally I would like to only run that yaml code onto the GPU node. How can I achieve that?
Yes, You can run the Deamon set on each node which will run the command on Nodes.
As you are on GKE and Daemon set will also run the command or script on New nodes also which are getting scaled up also.
Daemon set is mainly for running applications or deployment on each available node in the cluster.
We can leverage this deamon set and run the command on each node that exist and is also upcoming.

QUESTION
Is there any way to declare in Puppet's language that packages in an array should installed in the order they are given in the array?
I want to automate the installation of CUDA, which requires nvidia-driver-latest-dkms
, cuda
and cuda-drivers
(on RHEL7 as an example) to be installed in that order. I do not want to hard-code the array of packages, because I need to support different distributions, which require different packages. Therefore, an array holding the packages provided via Hiera seemed to be a good idea.
My first solution was ensure_packages($packages_parameter_filled_via_hiera)
, which stopped working recently (probably due to changes in NVIDIA's packages). The problem seems to be that this code installs the packages in a random order, and you cannot install nvidia-driver-latest-dkms
(any more) if any of the other packages is already installed.

ANSWER
Answered 2021-Dec-15 at 08:44@DazWilkin's comment is correct:
It's not possible to install graphics driver to Cloud Run fully managed because it doesn't expose any GPU.
You should deploy it in Cloud Run Anthos(GKE). But you'll need to configure your GKE Cluster to install your GPU, According to the documentation, you should follow the steps:
In this step, you can enable Enable Virtual Workstation (NVIDIA GRID). Please choose a GPU such as NVIDIA Tesla T4, P4 or P100 to enable NVIDIA GRID.
You can now create a service that will consume GPUs and deploy the image to Cloud Run for Anthos:
