Warp size also explains the horizontal lines every 32 threads per block. When block are are evenly divisible into warps of 32, each block uses the full resources of the CUDA cores on which it is run, but when there are (32 * x) + 1 threads, a whole new warp must be scheduled for a single thread which wastes 31 cycles cycles per block..

A warp comprises 32 lanes, with each thread occupying one lane. For a thread at lane X in the warp, __shfl_down_sync(FULL_MASK, val, offset) gets the value of the val variable from the thread at lane X+offset of the same warp.

CUDA core - a single scalar compute unit of a SM. Their precise number depends on the architecture. Each core can handle a few threads executed concurrently in a quick succession (similar to hyperthreading in CPU). In addition, each SM features one or more warp schedulers. Each scheduler dispatches a single instruction to several CUDA cores..

To execute 32 threads on 8 processors, each processor executes 4 threads - that’s why most instructions have a throughput of one instruction every four clock cycles. alwayssmile68 July 16, 2010, 11:05am #3. So far all CUDA devices have had a warp size of 32.. A thread block is a programming abstraction that represents a group of threads that can be executed serially or in parallel. For better process and data mapping, threads are grouped into thread blocks. The number of threads in a thread block was formerly limited by the architecture to a total of 512 threads per block, but as of March 2010, with. Warps A warp is a group of 32 threads from the same thread block that are executed in parallel at the same time. Threads in a warp execute on a so-called lock-step basis.

Warp; For SM(hardware), CUDA run as warp(线程束), SM don't know where the block, who they are. ... (size_t): specifies the number of bytes in shared memory that is dynamically allocated per block for this call in addition to the statically allocated memory. S (cudaStream_t): specifies the associated stream, is an optional parameter which. The blocksize in CUDA is always a multiple of the warp size. The warp size is implementation defined and the numbe 32 is mainly related to shared memory organization, data access patterns and data flow control [ 1 ]. So, a blocksize being a multiple of 32 does not improves performance but means that all the threads will be used for something.
