Webb26 sep. 2013 · In order to actually achieve the high memory bandwidth for concurrent accesses, shared memory is divided into equally sized memory modules (also known as banks) that can be accessed simultaneously. This means any memory load/store of N memory addresses than spans N distinct memory banks can be serviced simultaneously … Webbmemory, on the other hand, avoids the contention. Shared memory is allocated either statically, or dynamically, which means the allo-cation sizes only become apparent during the GPU kernel launch. The shared memory is organized into banks; threads in a warp accessing memory in the same bank see longer latencies. It is the bishop heber school uniform
