[QST] The code location where the shared memory write by swizzled layout occurs in cutlass 2.x?

[danielhua23]

What is your question?

Dear cutlass team，

Happy new year！
I wanna consult the question as the title. I only found that the shared memory ldsm read is done by MmaTensorOpMultiplicandTileIterator. To my knowledge, the shared memory write by swizzled layout w/o bank conflict should occur in RegularTileAccessIterator, which but I think did not implement it. So Could you pls guide me the code location where shared memory write by swizzled layout occurs in cutlass 2.x?

Thanks.

You are right that shared memory write is implemented in RegularTileAccessIterator

Have you found the line where the swizzling call is applied? Thanks.
