Script.tcgen05.relinquish_alloc_permit(cta_group)[source]

Relinquish the tensor memory allocation permit.

After this instruction, the current CTA group can no longer allocate tensor memory until the permit is re-acquired (which happens implicitly after deallocation). This allows the peer CTA group to allocate tensor memory.

Parameters:

cta_group (int) – The CTA group whose allocation permit is being relinquished. Must be 1 or 2.

Return type:

None

Notes

  • Thread group: Can be executed by any sized thread group.
