 ### Miscellanea
 
 - When transferring lots of small data arrays, try to combine them. For strided data, try to use `cudaMemcpy2D` or `cudaMemcpy3D`. Otherwise, try to copy the small arrays into a single, temporary, pinned array.
+- For getting device attributes/properties, `cudaDeviceGetAttribute` is significantly faster than `cudaGetDeviceProperties`.
