Expand description
place — pin every work item, stage and buffer to a site and an engine.
Blocked plans map output block (oy, ox) to site (x = ox, y = oy) — the alignment that lets a row of
sites share its A blocks and a column its B blocks (a sequential n % grid_x mapping would break reader
fusion). Streaming plans reproduce tt-metal’s split_work_to_cores exactly (column-major core-range
selection, x-fastest offsets inside each range), so the streamed program is the vendor’s cycle-for-cycle.
After placement stages and buffers are explicit PER-SITE INSTANCES (origin remembers the template), and
every engine slot carries the NOC the target’s rule assigns.
