CUDA kernels and MAGMA with 64-bit integer

[Xiniz Ronda]

Hi to All,

As we talked about before I did the compilation with a 64-bit integer. Now I have a question about the CUDA kernels that are included in MAGMA. Should I change CUDA kernels too? Because inside of them I am seeing using of int which means 32-bit integer (not magma_int_t). 

Changing them seems crazy. Because there are so many.

Hi Xin,

Yes, that may indeed be crazy because there are many.

The design has been to use “magma_int_t" at key places and to still have “int"

in most of the kernels. After magma_int_t is replaced by 64-bit integers, everything should

work without any further changes. However, probably there are bugs and more “int”s have to be

replaced by magma_int_t. Ideally we would like to change only where needed.

We have done fixes to a few places.

Have you located a particular problem that may need local fix (vs. changing every int to magma_int_t)?

Thanks,

Stan
