NEW QUESTION 50
You’re using Docker Compose to manage a multi-container application that includes a GPU-accelerated container. The application runs fine locally, but when deployed to a cloud environment, the GPU container fails to start with a ‘device not found’ error. What are the potential reasons for this failure?

The cloud environment does not have NVIDIA GPUs available. Verify that the cloud instance type includes NVIDIA GPUs.

The NVIDIA drivers are not installed on the cloud instance. Install the appropriate NVIDIA drivers for the cloud instance’s operating system.

The Docker daemon on the cloud instance is not configured to use the NVIDIA runtime. Configure the Docker daemon as described in NVIDIA’s documentation.

The Docker Compose file does not specify the ‘-gpus all’ flag for the GPU container. Add ‘deploy: ‘ and ‘resources:’ sections to your docker-compose.yml to specify GPU requirements.

The Docker image is too large to be deployed in the cloud environment. Optimize the Docker image size to reduce deployment time.

You are managing a deep learning workload on a Slurm cluster with multiple GPU nodes, but you notice that jobs requesting multiple GPUs are waiting for long periods even though there are available resources on some nodes.
How would you optimize job scheduling for multi-GPU workloads?

Reduce memory allocation per job so more jobs can run concurrently, freeing up resources faster for multi-GPU workloads.

Ensure that job scripts use –gres=gpu:<number> and configure Slurm’s backfill scheduler to prioritize multi-GPU jobs efficiently.

Set up separate partitions for single-GPU and multi-GPU jobs to avoid resource conflicts between them.

Increase time limits for smaller jobs so they don’t interfere with multi-GPU job scheduling.

NEW QUESTION 54
You have a cluster dedicated to AI inference, serving models from a persistent volume. You’re experiencing high latency and CPU usage on the nodes serving inference requests. You suspect that storage access patterns are contributing to the issue. Your persistent volume is backed by a distributed file system. Describe a strategy, including relevant tools and techniques, to analyze the storage I/O profile of your inference workloads and identify potential optimizations.

Use ‘iotop’ or ‘iostat’ on the compute nodes to monitor real-time I/O activity and identify processes with high disk I/O. Then check the related containers that are doing more of these reads/writes.

Capture network traffic using ‘tcpdump’ or Wireshark to analyze the communication patterns between the compute nodes and the storage system. Look for excessive network latency or congestion. Also monitor the network latency using tools like ‘ping’ or ‘iperf.

Utilize the distributed file system’s monitoring tools (if available) to analyze I/O patterns at the file system level. This can reveal hotspots or inefficient data access patterns.

Randomly restart the inference pods. If the issue goes away, it means the storage system was temporarily overloaded.

Implement storage QOS (Quality of Service) policies to prioritize inference workloads and limit the impact of other I/O-intensive processes.

NEW QUESTION 55
Explanation:
You are running a Docker container that utilizes NVIDIA GPUs for deep learning inference. The application inside the container fails to detect the GPUs. You’ve verified that NVIDIA drivers are installed on the host. What is the MOST likely cause and how do you fix it?

The NVIDIA Container Toolkit is not installed or configured correctly on the host machine. Install and configure the toolkit following NVIDIA’s official documentation.

The Docker daemon is not configured to use the NVIDIA runtime. Modify the ‘/etc/docker/daemon.json’ file to include “‘default-runtime”: “nvidia”‘ and restart the Docker daemon.

The CUDA version in the container does not match the driver version on the host. Ensure the container uses a CUDA version compatible with the host driver.

The ‘”gpus all’ flag was not used when running the container. Re-run the container with ‘docker run -gpus all …w.

The host’s firewall is blocking communication between the container and the NVIDIA drivers. Disable the firewall or create an exception for the container network.

NEW QUESTION 56
A BCM pipeline running a large language model (LLM) experiences significant latency during inference. Profiling reveals that the ‘torch.compile’ is taking too much memory and time. What optimization strategies would you consider to improve inference performance?

Utilize quantization techniques (e.g., INT8 or FP16) to reduce the model size and memory footprint.

Employ model parallelism to distribute the LLM across multiple GPUs.

Use techniques like speculative decoding or continuous batching to increase throughput.

Try different ‘mode’ arguments for ‘torch.compile’ such as ‘reduce-overhead’ or ‘max-autotune’.

All of the above.

Ensure that Docker is installed and running on all control-plane nodes.

Configure each control-plane node with its own external IP address.
