Set some constant memory on GPU
setConstantMemory(kern,sym,val) sets the
constant memory in the CUDA kernel
kern with symbol
sym to contain the data in
be any numeric array, including a gpuArray. The command errors if
the named symbol does not exist or if it is not big enough to contain
the specified data. Partially filling a constant is allowed.
There is no automatic data-type conversion for constant memory, so it is important to make sure that the supplied data is of the correct type for the constant memory symbol being filled.
multiple constant symbols.
KERN represents a CUDA kernel whose CU
file contains the following includes and constant definitions:
#include "tmwtypes.h" __constant__ int32_t N1; __constant__ int N2; // Assume 'int' is 32 bits __constant__ double CONST_DATA;
you can fill these with MATLAB data as follows:
KERN = parallel.gpu.CUDAKernel(ptxFile,cudaFile); setConstantMemory(KERN,'N1',int32(10)); setConstantMemory(KERN,'N2',int32(10)); setConstantMemory(KERN,'CONST_DATA',1:10);
