Researchers have developed DynaResize, a system designed to optimize GPU resource allocation during the post-training phase of large language models (LLMs). This system dynamically reallocates GPUs between rollout and training stages to mitigate pipeline bubbles caused by long-tail rollout latency. DynaResize achieves this by decomposing resizing into fine-grained operations and employing techniques like communicator reuse and hysteresis-based resizing, leading to significant improvements in throughput and reductions in execution time compared to static configurations.
