The limitations on gpumem and gpucores are not working correctly. #332

1. Issue or feature description

Hi HAMi team,

I configured a pod with the image oguzpastirmaci/gpu-burn for testing GPU burn, but when running the burn, it's still using 100% of the GPU card's utilization (100 cores over the 20 cores configuration) and exceeding the memory limit (1332 MiB over the 1000 MiB configuration).

2. Steps to reproduce the issue

Deploy the pod

apiVersion: v1
kind: Pod
metadata:
  name: gpu-pod
spec:
  runtimeClassName: nvidia
  containers:   
    - name: ubuntu-container1
      image: oguzpastirmaci/gpu-burn
      imagePullPolicy: IfNotPresent
      command: ["bash", "-c", "sleep 86400"]
      env:
      - name: ACTIVE_OOM_KILLER
        value: "true"
      - name: GPU_CORE_UTILIZATION_POLICY
        value: force
      resources:
        requests:
          cpu: 1
          memory: 1Gi
          nvidia.com/gpu: 1
          nvidia.com/gpumem: 1000
          nvidia.com/gpucores: 20
        limits:
          memory: 1Gi
          nvidia.com/gpu: 1
          nvidia.com/gpumem: 1000
          nvidia.com/gpucores: 20

Then run burn

./gpu_burn 1000

i see, is the utilization of GPU vibrate from 0-100 during execution or stable at 100

it's alway stable at 100%

could you try using tensorflow/pytorch benchmarks(https://github.com/tensorflow/benchmarks), HAMi-core implement gpucores limitation by blocking new kernels from running, so if you have a very very large kernel already submitted, then we can't do anything to limit its utilization

I'll try.

Additionally, when setting

export LIBCUDA_LOG_LEVEL=4

the log is:

I copied these logs from inside the pod. I don't know how to copy the full entries because they don't show in the pod log (via console), so I can't write them to a log file.

@thungrac You can use Python's > or >> operators to redirect output to a file. The > operator creates a new file, or overwrites the file if it already exists. The >> operator appends content to the end of an existing file, or creates a new file if it does not exist. If you want to store both standard output (stdout) and error output (stderr) in the same file, you can use 2>&1, which means to redirect standard error 2 to standard output 1. The "> &" operation redirects standard output to a file, and then "2 > &1" redirects standard error to the current standard output, i.e., the previously specified file. (Please note, the following syntax is in Unix/Linux shell, such as bash/sh etc. If you are using Windows's cmd or powershell, the syntax may vary a bit) Here are the specific Python commands:

python train.py config/train_shakespeare_char.py > output.txt 2>&1

or

python train.py config/train_shakespeare_char.py >> output.txt 2>&1

This way, the output.txt file will contain all output from your program.

@haitwang-cloud many thanks

Here is the output when i run ./gpu_burn 10 when setting export LIBCUDA_LOG_LEVEL=4
