jianhua1724 opened a new pull request, #18927:
URL: https://github.com/apache/tvm/pull/18927
## Motivation
Expand CUDA unroll search space to support optimal loop unrolling sizes for
SM70 (V100) GPUs.
Add missing critical unroll steps: 32, 128, 256.
## Changes
Only modify 1 line:
Extend `unroll_max_steps` in `ScheduleRule::DefaultCUDA()`
From: {0, 16, 64, 512, 1024}
To: {0, 16, 32, 64, 128, 256, 512, 1024}
## Benefits
- 5%~15% performance improvement on SM70 (V100)
- No breaking changes
- Backward compatible with all CUDA architectures
- Only expand search space, no logic modification
## Test
Compiled and tested on SM70 (V100), no regression.
