Graphs in llama.cpp

[abhinav9629]

Hi
I'm trying to debug and understand the codebase of llama.cpp
I have a couple of questions regarding graph creation.

• In llama_new_context_with_model whats the need of two graphs pp and tg graph?
• What exactly is the worst case scenario for which we reserve a worst case graph?
• Why we need to reserve a worst case graph again in case kv cache defragments or K shift is there?
