questions about the kernels

[zjin-lcf]

I have some questions about your kernels.
1 Do you mind providing a CPU version (serial/openmp) of the metropolis kernel for reference and verification ?
2 When the maximum block size is 256 on a GPU, what are the values of BX, BY, and BZ ?

/* warning: changing the block dimensions can lead to undefined behavior. */
#define WARPSIZE 32
#define BX  32
#define BY  8
#define  BZ  4

Hi zjin-lcf

1. Unfortunately at this moment I do not have a CPU version at hand for verification. I will look into historic implementations and if I find something I will let you know.
2. I would try BX=32, BY=4, BZ=2. Let me know if the program crashes or not.
