NIC atomic operation unit with caching and bandwidth mitigation

DWPI Title: Network interface controller for use with host processor in computer, has atomic operation unit comprising rate-limiting functional unit that writes first update to write-through cache based upon second update in register file
Abstract: A network interface controller atomic operation unit and a network interface control method comprising, in an atomic operation unit of a network interface controller, using a write-through cache and employing a rate-limiting functional unit.
Use: Network interface controller for use with a host processor in a computing device i.e. computer.
Advantage: The controller purges items from a secondary buffer and minimizes required buffer size in a quick manner. The controller sustains high performance under certain workloads. The controller eliminates a need for explicit flushes of the cache or tuning of time-outs by making the cache write-through, while retaining benefit of reduced bandwidth requirements in an efficient manner.
Novelty: The controller (10) has an atomic operation unit comprising a rate-limiting functional unit (14) that executes atomic operations and writes data to write-through cache (16) based upon operations. The operations comprise first atomic operation received from first node and comprise second atomic operation received from second node. The functional unit writes first update to a file (56), while refraining from writing first update to cache based upon the second operation that is included in a look-ahead window. The functional unit writes second update to cache based upon first update in the file.
