Summary

By comparing custom tokenizers with custom models, the workflow remains largely similar despite the hardware differences. The core challenge of porting single-GPU to multi-GPU code is becoming clearer when analyzing specific technical hurdles, such as resource constraints. The setup requirements for these different implementations are not entirely separate, yet the specific environment choices often shift to optimize performance.

After extensive research involving various hardware investments, I found that the most efficient resources for completing a single-epoch run were located. A reasonably cheap instance on Lambda Labs with 8x A100 GPUs and 40 GiB VRAM per unit was the sweet spot. These servers offer substantial VRAM capacity to handle high-dimensional data effectively without crashing.
