Hello. Thank you for using our NPB version and reporting this issue.
We have recently solved a similar issue in the IS benchmark (concerning the class D and overflow with int numbers).
A way to solve this is creating a macro that uses long type instead of int type when running the class D or larger.
A macro should be something like this:
#if CLASS == 'D'
typedef long INT_TYPE;
#else
typedef int INT_TYPE;
#endif
After that, you can replace the int type in the source code with that macro:
// using int type
int number;
// using the macro for class D
INT_TYPE number;
We will provide this update in the FT benchmark as soon as possible.
Additionally, since class D consumes a lot of memory, you should verify if your GPU has enough memory.
