Embodiments of the present disclosure relate to partition aware broadcast operation filtering in a multiprocessor system. Various embodiments include techniques for processing broadcast operations in a computing system. Typically, broadcast operations are sent to all portions of a particular subsystem, such as all cache slices in cache memory, etc. Thus, a process that issues a broadcast operation may interfere with one or more other processes that access portions of the subsystem that are not allocated to the process. To prevent such interference, logic in the computing system filters broadcast operations in order to send broadcast operations to relevant portions that are only allocated to processes that emanate the broadcast operations. The logic tracks acknowledgements from the relevant portion and when all suspended acknowledgements have been received, the logic sends a single acknowledgement to the process issuing the broadcast operation. The logic is dynamically configurable such that the logic can change portions of the subsystem allocated to each process as needed.

A storage system caches logical-to-physical address table entries read in volatile memory. The logical-to-physical address table entries are stored in codewords. The storage system can change the number or size of entries in a codeword. Additionally or alternatively, each codeword can store both a full logical-to-physical address table entry and a partial logical-to-physical address table entry. In one example, a codeword with 62 bytes of data and two bytes of error correction code stores 15 full logical-to-physical address table entries and one partial logical-to-physical address table entry, with the remainder of the partial entry stored in another codeword. This configuration achieves a good balance between storage space efficiency and random access write performance.
