Here’s the problem I’ve observed: Taking the code that worked (and compiled) perfectly fine in CUDA 3.2, and recompiling with CUDA 4.0RC2 on the same machine, I get the following error: “Error: Const space overflowed.”
After some digging, an even more mystifying discovery. The following code compiles in 4.0RC2:
//#include “curand_kernel.h” //this line causes the constant mem overflow error!
using namespace std;
constant float stuff;
Please note the commented out curand_kernel header. Including that header results in the above error! In fact, with the “curand_kernel.h” in, the largest number of floats that can be allocated to constant mem becomes 3,584, equivalent to 14,336k.
Is this a known issue and will it be resolved in the final 4.0 release?
Thanks in advance for any ideas.
