Cache model and replacement policies for GPU memory

Hi, Is there anyone who know the cache model and their replacement polices for off-chip and on-chip memory in gpu?

L2 Cache: Set-associative ? LRU?
L1 Cache :Set-associative ? LRU?
Texture L1:Set-associative ? LRU?
Constant L1 cache:Set-associative ? LRU?

My current approach is to develope micro-benchmark to reveal such details.

The site hgpu.org is always a good place to check:

Dissecting GPU Memory Hierarchy through Microbenchmarking

thank you, it’s a lot of information for me. unfortunately, searching for gpu internals is like digging for a gold :)

You are miss leading the community!

It is totally wrong! L2 cache is on-chip!! please get a clear definition of on-chip and off-chip!!

and the results in the paper https://arxiv.org/abs/1509.02308 are totally wrong!
