##############################
### Math Lib
##############################
### The math library can be built to support a number of GPU platforms using the
### common compute_50 architecture.
### For a collection of specific architecutres, the compiler options
### "-gencode=compute_XX,code=sm_XX"... can be used multiple times in the same
### nvcc invocation.
### The result is bundled into a system library using the 'nvcc -lib' feature.
### >> nvcc -m64 -arch=compute_50 -dc math-funcs.cu -o math-funcs64.o
### >> nvcc -m64 -lib math-funcs64.o -o libmathfuncs64.a
