Good point. That FAQ entry was written before VexCL added its CUDA
back-end (which occurred relatively recently). Boost.Compute and VexCL
have different aims and scopes. Boost.Compute is more similar to the
C++ STL while VexCL is more similar to a linear algebra library like
Eigen. Also see this StackOverflow question [1] entitled "Differences
between VexCL, Thrust, and Boost.Compute".
