Description
Summary
Add ESIMD mode to GPU Occupancy Calculator
Problem statement
ESIMD mode has a sub-group size of 1. Uses do have a workaround to manually choose a random sub-group size and multiply it to wg size and global size. But a separate option is better.
Preferred solution
Add an option to SIMD/sub-group size dropdown.
