I am here to ask about reformatter on TensorRT.
When I ran trtexec, I found this phrase ‘input reformatter 0’ and ‘output reformatter 0’ from log.
What is the meaning of those phrases? What is the meaning(or role) of 0?
I found that
“TensorRT will always insert a reformat layer at the DLA boundary. Input reformats are inserted to synchronize tensors from a CUDA address space to an NvMedia address space.”.
However, what is the meaning of ‘synchronizing tensors from a CUDA address space to a NvMedia address space’?
