An SMP encompasses 128 single-precision ALUs ("CUDA cores") on GP104 chips and 64 single-precision ALUs on GP100 chips. Streaming Multiprocessor "Pascal" Ī "Streaming Multiprocessor" corresponds to AMD's Compute Unit. For the GP104 chips, a GPC encompasses 5 SMs. Overview Graphics Processor Cluster Ī chip is partitioned into Graphics Processor Clusters (GPCs). Therefore the driver enables the expensive instruction-level preemption for these tasks. Compute tasks get thread-level or instruction-level preemption, because they can take longer times to finish and there are no guarantees on when a compute task finishes. In graphics tasks, the driver restricts preemption to the pixel-level, because pixel tasks typically finish quickly and the overhead costs of doing pixel-level preemption are lower than instruction-level preemption (which is expensive).
