Abstract: A device receives an indication that a memory bank is to be powered up, and determines, based on receiving the indication, power scores corresponding to powered down memory banks. Each power score corresponds to a power metric associated with powering up a powered down memory bank. The device powers up a selected memory bank based on the plurality of power scores.

Abstract: A system and method for accessing a hash table are provided. A hash table includes buckets where each bucket includes multiple chains. When a single instruction multiple data (SIMD) processor receives a group of threads configured to execute a key look-up instruction that accesses an element in the hash table, the threads executing on the SIMD processor identify a bucket that stores a key in the key look-up instruction. Once identified, the threads in the group traverse the multiple chains in the bucket, such that the elements at a chain level in the multiple chains are traversed in parallel. The traversal continues until a key look-up succeeds or fails.

Abstract: A device receives an indication that a memory bank is to be powered down, and determines, based on receiving the indication, shutdown scores corresponding to powered up memory banks. Each shutdown score is based on a shutdown metric associated with powering down a powered up memory bank. The device may power down a selected memory bank based on the shutdown scores.

Abstract translation: 设备接收到存储器组要断电的指示，并且基于接收到指示确定与加电的存储体相对应的关断分数。 每个停机分数都是基于与断电加电存储器相关联的停机度量。 该设备可以基于关闭分数关闭选定的存储体。
