How GPU and CPU Work in Parallel Computing

CPU, or the central processing unit, is often considered the "brain" of a computer. It is responsible for running the operating system, interacting with different programs, and connecting various hardware components. However, CPUs are not particularly well-suited for tasks that require massive parallel computing, such as gaming or training deep learning models.

This is where GPUs, or graphics processing units, come into play. GPUs have a fundamentally different architecture compared to CPUs. While a high-end CPU like the Intel i9 may have 24 cores, a GPU like the Nvidia RTX 480 can have almost 10,000 cores. This massive parallelism allows GPUs to excel at tasks that can be broken down into smaller, independent subtasks that can be executed simultaneously.

The key difference between CPUs and GPUs is their approach to task execution. CPUs are designed for sequential, linear processing, where they execute tasks one after the other, even though they may appear to be multitasking due to their speed. GPUs, on the other hand, are optimized for parallel processing, where they can execute hundreds of tasks simultaneously.

This difference in architecture is demonstrated in the "CPU painting" and "GPU painting" examples. In the CPU painting demonstration, the task of painting the Mona Lisa is executed sequentially, with each step performed one after the other. In contrast, the GPU painting demonstration shows how the same task can be broken down into thousands of independent subtasks, which are then executed in parallel, resulting in a much faster completion time.

The reason why GPUs are so effective for tasks like gaming and deep learning is that these tasks can be easily parallelized. For example, in gaming, each pixel on the screen can be calculated independently, allowing the GPU to process them simultaneously. Similarly, in deep learning, the training of a neural network can be divided into smaller, independent computations that can be executed in parallel on a GPU.

However, the sequential nature of large language model inference, where the prediction of each new word depends on the previous words, poses a challenge for GPUs. This is where the Grok LPU (Large Language Model Processing Unit) comes into play. The Grok LPU is designed specifically for large language model inference, with a simpler architecture and direct shared memory across all processing units, allowing for more predictable and lower-latency performance compared to GPUs.

In summary, CPUs and GPUs have fundamentally different architectures and are suited for different types of tasks. CPUs excel at sequential, linear processing, while GPUs are optimized for parallel processing, making them more suitable for tasks that can be easily parallelized, such as gaming and deep learning. The Grok LPU, on the other hand, is designed specifically for large language model inference, addressing the challenges posed by the sequential nature of this task.

Why GPU is Not Sufficient for Large Language Model Inference

GPU has fundamentally different architecture compared to CPU. While CPU is designed for sequential tasks, GPU is optimized for parallel processing. The state-of-the-art CPU like Intel i9 has 24 cores, whereas a GPU like Nvidia RTX 480 can have almost 10,000 cores.

This massive parallelism makes GPU extremely powerful for tasks that can be broken down into independent subtasks, such as gaming and graphics rendering. However, this architecture also leads to some challenges for large language model inference:

  1. Latency and Unpredictable Results: The nature of large language models is sequential, as each new word prediction depends on the previous ones. The complex control logic required to manage the data flow and execution order on a GPU can lead to unpredictable latency and results.

  2. Optimization Complexity: To optimize the performance of large language model inference on a GPU, developers need to write complex CUDA kernel code to manage the data flow and execution order. This is a time-consuming process that requires significant engineering effort.

In contrast, the Graphcore IPU (Intelligence Processing Unit) is designed specifically for sequential tasks like large language model inference. The IPU has a much simpler architecture with a single core, but with direct shared memory access across all processing units. This predictability leads to lower latency and better resource utilization, without the need for complex optimization.

The Graphcore IPU's specialized architecture makes it a more suitable choice for large language model inference, unlocking use cases that require real-time, low-latency performance, such as voice AI and real-time image/video processing.

How Groq LPU is Designed for Sequential Tasks

GPUs are general-purpose processing units designed for parallel tasks, which makes them well-suited for training AI models. However, for large language model inference, GPUs have some limitations:

  • Latency and Unpredictable Results: The complex, multi-core architecture of GPUs can lead to unpredictable latency and results when executing sequential tasks like language model inference, where the order of execution matters.
  • Optimization Complexity: Optimizing GPU performance for sequential tasks requires writing complex CUDA kernel code, which is time-consuming and requires significant engineering effort.

In contrast, Groq's LPU (Language Processing Unit) is designed specifically for sequential tasks like large language model inference:

  • Simplified Architecture: Unlike GPUs with thousands of cores, the LPU has a single, simplified core. This architecture is optimized for predictable, sequential execution.
  • Direct Shared Memory: All processing units in the LPU have direct access to shared memory, allowing them to know exactly what tokens have been generated before, improving predictability and performance.
  • Predictable Performance: The high predictability of the LPU's data flow leads to much higher resource utilization and more predictable performance for developers, without the need for complex optimization.

In summary, the LPU's streamlined design for sequential tasks, in contrast to the general-purpose, parallel architecture of GPUs, makes it a powerful solution for large language model inference, enabling low-latency, real-time applications like voice AI and image/video processing.
