Detailed Description

CUDA device-side functions having to do with timing and the hardware clock.

Function Documentation

sleep()

template<sleep_resolution Resolution = sleep_resolution::clock_cycles>

KAT_DEV void kat::sleep ( sleep_unit_t< Resolution >  num_cycles )

delete

Have the calling warp busy-sleep for (at least) a certain number of clock cycles.

Note

In 2017, a typical GPU clock cycle is around 1 ns (i.e. 1 GHz frequency).
