摘要： A GPU and a GPU method are provided. The GPU includes stream multiprocessors, an available hardware resource table, resource comparator, stream scheduler, and global dispatcher. Each stream multiprocessor executes at least one thread block. The available hardware resource table records hardware resources available to the stream multiprocessors. The resource comparator selects from first-priority kernel codes in the kernel streams at least one first dispatchable kernel code whose required hardware resources are less than hardware resources available to the stream multiprocessors according to the available hardware resource table. The stream scheduler selects from the at least one first dispatchable kernel code a kernel code as a selected kernel code. The global dispatcher dispatches thread blocks in the selected kernel code to the stream multiprocessors for execution and updates the available hardware resource table according to usage conditions of hardware resources of the stream multiprocessors.

摘要： The present application discloses a warp execution method used for SPs of an SM of a GPU and an associated GPU. The SPs share a scratchpad memory, and the warp execution method includes: when the predetermined time point for warp-loading is reached, checking a first indicator to obtain a size of a space with the status of blank in the scratchpad memory, to determining whether to load the warp, wherein the first indicator is used to indicate a starting position of a space with the status of data-in-use and an ending position of the space with the status of blank; and when the predetermined time point for computing is reached, checking a second indicator and a third indicator to obtain a size of a space with the status of data-not-in-use in the scratchpad memory, to determining whether to compute the warp

摘要： A stream multiprocessor, a GPU, and related methods are provided. The stream multiprocessor executes thread blocks. Each thread block includes warps. The stream multiprocessor includes stream processors and a local dispatcher. Each stream processor executes one or more warps. The local dispatcher includes a warp state table, a warp resource detection unit and a warp launching unit. The warp state table records dispatching states and processing states of warps of the thread blocks. The warp resource detection unit selects all the first warps of a first thread block and at least one second warp of a second thread block according to hardware resources available to the stream multiprocessor and hardware resources required for thread blocks. The warp launching unit dispatches the first warps to idle stream processors and at least one second warp to at least one idle stream processor.
