Mojo function

warpgroup_reg_dealloc

warpgroup_reg_dealloc[count: Int]()

Deallocates additional registers for the executing warp group.

This function provides a hint to the system to decrease the maximum number of per-thread registers owned by the executing warp. It releases extra registers to reduce the absolute per-thread maximum register count from its current value to the specified count.

Note: - Only supported on NVIDIA SM90+ GPUs. - This is a performance optimization hint that may be ignored by the hardware. - Should be paired with warpgroup_reg_alloc() when extra registers are needed.

Parameters:

• ​count (Int): The desired number of registers per thread. Must be: - A multiple of 8. - Between 24 and 256 (inclusive).
