When a Grid is launched, the architecture guarantees that all threads within a CTA will run concurrently on the same SM. Information on the grids and blocks can be found in the Launch Statistics section. The number of CTAs that fit on each SM depends on the physical resources required by ...
Functions with highKthr Timemetrics, but low KCPU Cycles metrics, are functions that are spending a lot of time for the profiled threads waiting for some other events. Analyzing a Kernel Profile A few of the recorded fields inkernel experiments have a different meaning from the same fields ...
Kernel-level thread. A kernel-level thread employs a strict 1:1 model whereby each user thread maps directly to a kernel thread. The issue here is the potential overhead of the kernel creating and maintaining new threads, especially for applications that may use a lot of threads. However, ...
VMware calls VMkernel amicrokernelbecause it runs onbare metal, or directly on VMware ESX hosts. It includes many functions that are also available in other OSes, such as process creation, process control, process threads, signals,file system, etc. ...
Kernel Execution refers to the process of running a grid of blocks on a CUDA device, where each block consists of multiple threads. The execution is organized in a hierarchical and multidimensional manner, with each block being assigned to a streaming multiprocessor (SM) for execution. The thread...
