The alls line has nothing to do with compilation speed. It simply allows one to split the model into multiple contexts so that the Hailo chip can execute each context sequentially in chunks. The error message that you posted earlier suggested that the compiler was trying to fit everything into one context.
The compilation time if there is no finetuning/adaround (these two optimizations should use GPU, everything isn’t necessary) is dominated by LP/MIP problems. The hailo compiler looks like it is using COIN-OR, which needs to be specifically built to support multithreading. Even then, multithreading is not guaranteed to accelerate MIP solving, depending on the problem itself.
Anyways, you need to post more info on what you’re doing or the onnx itself. There’s not enough information to replicate or help.
See,
Network Graph Compilation Failure - #3 by omria for the same exception you just posted.
