4Design a balanced PCIe topology to minimize latency and maximize performance.A well-structured PCIe layout ensures that data flows efficiently between components, which is critical for achieving optimal performance in multi-GPU setups.
Common Pitfalls
1
Neglecting the importance of system memory can lead to performance bottlenecks.
If the system memory is insufficient, the CPU may not be able to keep up with the GPU, causing delays in data processing and reducing the overall efficiency of the training pipeline.
2
Overlooking the need for a high-performance CPU can starve the GPU of data.
A low-performance CPU may not process data quickly enough, resulting in the GPU waiting idly for input, which can significantly slow down the training process.
