inlinestatic

Runs single GEMM problem cooperatively by whole workgroup.

Note

The GEMM pipeline is selected in-kernel based on the number of K-loops and the tail-number. This is needed for the persistent tile-loop when we didn't have access to the K dimension on the host.

Parameters

a_ptr	input A pointer
b_ptr	input B pointer
c_ptr	output C pointer
smem_ptr_0	The start memory pointer of the shared memory block.
kargs	GEMM kernel arguments
splitk_batch_offset	splitk_batch_offset Utility structure used to calculate k batch.
block_idx_m	The GEMM's output M dimension tile index processed by this workgroup.
block_idx_n	The GEMM's output N dimension tile index processed by this workgroup.

Parameters

a_ptr	input A pointer
b_ptr	input B pointer
c_ptr	output C pointer
smem_ptr_0	The start memory pointer of the shared memory block.
smem_ptr_1	The second start memory pointer of the shared memory block.
kargs	GEMM kernel arguments
splitk_batch_offset	splitk_batch_offset Utility structure used to calculate k batch.
block_idx_m	The GEMM's output M dimension tile index processed by this workgroup.
