WebbThe total amount of shared memory is listed as 49kB per block. According to the docs (table 15 here ), I should be able to configure this later using cudaFuncSetAttribute () to as much as 64kB per block. However, when I actually try and do this I seem to be unable to reconfigure it properly. Example code: However, if I change int shmem_bytes ... Webbillustrates the basic features of memory and thread management in CUDA programs – Leave shared memory usage until later – Local, register usage – Thread ID usage – Memory data transfer API between host and device – Assume square matrix for simplicity canine renal disease symptoms

WebbShared memory is memory which can be read and written to by all the threads in a given block. Shared memory cannot be accessed by threads not in the specified block. This is illustrated in the diagram below. In the code we wrote for vector addition, we did not use shared memory. Instead we used global memory.
