02What do gpu_memory_utilization, max_model_len and max_num_seqs each control in vLLM, and how do they interact at startup?▼easyNewAnyscaleRed HatDatabricksunlockedThree flags, three different budgets, and one startup check that fails a 70B deployment on two H100s with a message most people misread. The answer walks the memory profile in the order vLLM runs it.Open full answer →
03vLLM fails to start with an out-of-memory error on a model that should fit. Walk through the startup memory profile.▼mediumNewRed HatAnyscaleBasetenunlocked141 GB of weights on 160 GB of GPUs, and the engine refuses to start. The answer walks the five phases of engine startup, shows which one failed from the log, and does the arithmetic that says the model never fit the way it was configured.Open full answer →
