Cuda shared memory alignment
Webshared memory banks are accessed by multiple threads at the same time, a memory access conflict will occur and the reads to the same memory bank will be serialized. There are two other types of memory available, texture- and constant memory, which will not be discussed here. In addition to the CUDA memory hierarchy, the performance of CUDA WebJan 25, 2013 · Shared memory accesses (as well as all other types) need to be aligned to the access size. So if you are accessing a uint4, then the address needs to be 128-bit …
