ScatterGatherAmd
struct ScatterGatherAmd[thread_layout: Layout, num_threads: Int = thread_layout.size(), thread_scope: ThreadScope = ThreadScope.BLOCK, block_dim_count: Int = 1]
AMD tile-based scatter-gather for DRAM-register data movement.
Parameters

Layout): Thread organization layout. - num_threads (
Int): Total threads (defaults to thread_layout size). - thread_scope (
ThreadScope): Thread execution scope (block or warp). - block_dim_count (
Int): Number of block dimensions.
Fields
