Detailed Description

CUDA kernel methods for basic operations on vectors.

vector_kernel.cu

CUDA kernel methods for basic operations on vectors.

Examples:

• vectorAddConstant(): d_vector + constant
• vectorAddUniform(): d_vector + uniform (per-block constants)
• vectorAddVectorVector(): d_vector + d_vector
