In this article, we will explore how to deploy GPU-based workloads in an EKS cluster using the Nvidia Device Plugin, and ensuring efficient GPU utilization through features like Time Slicing. We will also discuss setting up node-level autoscaling to optimize GPU resources with solutions like Karpenter. By implementing these strategies, you can maximize GPU efficiency and scalability in your Kubernetes environment.
Additionally, we will delve into practical configurations for integrating Karpenter with an EKS cluster, and discuss best practices for balancing GPU workloads. This approach will help in dynamically adjusting resources based on demand, leading to cost-effective and high-performance GPU management. The diagram below illustrates an EKS cluster with CPU and GPU-based node groups, along with the implementation of Time Slicing and Karpenter functionalities. Let's discuss each item in detail.
GPU: A Graphics Processing Unit (GPU) was originally designed to accelerate image processing tasks. However, due to its parallel processing capabilities, it can handle numerous tasks concurrently. This versatility has expanded its use beyond graphics, making it highly effective for applications in Machine Learning and Artificial Intelligence.
When a process is launched on GPU-based instances these are the steps involved at the OS and hardware level:
Compared to a CPU which executes instructions in sequence, GPUs process the instructions simultaneously. GPUs are also more optimized for high performance computing because they don't have the overhead a CPU has, like handling interrupts and virtual memory that is necessary to run an operating system. GPUs were never designed to run an OS, and thus their processing is more specialized and faster.
A Large Language Model refers to:
Ollama is the tool to run open-source Large Language Models and can be download here https://ollama.com/download

developer:src > ollama run llama3:8b >>> print all primes between 1 and n Here is a Python solution that prints all prime numbers between 1 and `n`: ```Pythondefprint_primes(n): forpossiblePrimeinrange(2, n + 1): # Assume number is prime until shown it is not.isPrime= Truefornumin range(2, int(possiblePrime ** 0.5) + 1): ifpossiblePrime% num== 0: isPrime= Falsebreakif isPrime: print(possiblePrime) n= int(input("Enter the number: ")) print_primes(n) ``` In this code, we loop through all numbers from `2` to `n`. For each number, we assume it's prime and then check if it has any divisors other than `1` and itself. If it does, then it's not a prime number. If it doesn't have any divisors, then it is a prime number. The reason why we only need to check up to the square root of the number is because a larger factor of the number would be a multiple of smaller factor that has already been checked. Please note that this code might take some time for large values of `n` because it's not very efficient. There are more efficient algorithms to find prime numbers, but they are also more complex.
Hosting LLMs on a CPU takes more time because some Large Language model images are very big, slowing inference speed. So, in the next post let's look into the solution to host these LLM on an EKS cluster using Nvidia Device Plugin and Time Slicing.
