Description

In 16B and 32B interleaved mode, how to calculate the globalStrides value?
In 32B interleave for FP16 as an example, the layout would be N (C/64) DHW C64, how to set the globalStrides in this case?

Research direction

No file or test is named. Start by tracing CUTLASS's interleaved layout and globalStrides definitions for 16B and 32B modes, using the stated FP16 N (C/64) DHW C64 example. Done means documenting the stride calculation and configuration clearly enough to validate that example.
