I’ve been testing some CUDA features/behaviours, and i couldnt find any documentation on this matter. If someone who experimented with this before could tell me his experience would be great.
kernel_name<<< num_blocks, 0 >>> (params);
What happens if i call a kernel with this configuration?? (i have a test program, and it works fine :S, but i dont know what CUDA does for real). Is not that i’m calling kernels with it, but im writting some kind of utility for CUDA and i would like to know if i should give support to 0 as a parameter.
I dont know, maybe 0 has some special meaning like… “let cuda guess what’s best for your architecture”, that’s what i would like to know, if it has some special meaning, or its just some non-supported random behaviour number.
