Mojo function
tcgen05_alloc
tcgen05_alloc[cta_group: SIMD[int32, 1]](ptr_tmem_addr: UnsafePointer[SIMD[uint32, 1], address_space=AddressSpace(3), alignment=16], num_cols: SIMD[uint32, 1])
Allocates tensor memory for use with tcgen05 instructions.
Note: This function is only available on NVIDIA Blackwell GPUs (SM 100+).
Parameters:
- cta_group (
SIMD[int32, 1]): The cooperative thread array (CTA) group ID.
Args:
- ptr_tmem_addr (
UnsafePointer[SIMD[uint32, 1], address_space=AddressSpace(3), alignment=16]): Shared memory pointer to hold tensor memory address. - num_cols (
SIMD[uint32, 1]): The number of columns to allocate.
