Web27 jun. 2011 · The CUDA compiler decides on the number of registers to use for a kernel based on its complexity. Such a compiled kernel is flexible enough to be launched with any number of threads or blocks. However, if an approximate idea of the number of threads and blocks is known at compile-time, then this can be used to optimize the kernel for such … WebTo prevent the compiler from allocating too many registers, use the -maxrregcount=N compiler command-line option (see nvcc) or the launch bounds kernel definition qualifier (see Execution Configuration of the CUDA C++ Programming Guide) to control the maximum number of registers to allocated per thread. 9.3. Allocation WebWe'll consider the following demo, a simple calculation on the CPU.
