Problems about Memory Hierarchy

[chiachia36]

Hi,

I'm trying to find some information about memory hierarchy.
I tried to use iree-translate to run the example matrix multiplication with print-ir-after-all to check every pass which the flow ran through.
Then I found that there is a dialect stream, and it has some operations about description of source.
However, after I checked the files StreamBase.td and StreamOps.td, I still didn't understand the resource architecture(e.g. DRAM, Global buffer, Cache...) very well.
If I want to check the resource architecture to do some analysis, how could I make it?

And I also want to ask the usage of PartitioningConfigAttr in StreamBase.td.
It mentions that it defines partitioning configuration, but I want to ask how to use it to define some partitioning information (e.g. single-thread/multi-thread).

Thanks a lot!
