Measuring performance of PyCUDA programs using CUDA events

So far, we have not determined the performance of the PyCUDA programs explicitly. In this section, we will see how to measure the performance of the programs using CUDA events. This is a very important concept in PyCUDA because it will allow you to choose the best performing algorithms for a particular application from many options.

CUDA events

We can use Python time measuring options for measuring the performance of CUDA programs, but it will not give accurate results. It will include the time overhead of thread latency in the OS and scheduling in the OS among many other factors. The time measured using the CPU will also depend on the availability of a high-precision...
