Pull request overview
This PR refactors tensor parallelism-related code by standardizing variable naming and improving bias handling for distributed training. The changes focus on code consistency and correctness without altering the core functionality.
- Standardizes variable naming from
nrankstotp_sizeacross multiple modules for better clarity - Introduces special handling for row-parallel bias division in tensor parallelism
- Removes unused variables and simplifies conditional logic in RowParallelLinear
