Thanks!

Is there any specific reason?  In case we want to use opencl, is there
a specific approach to follow?  Both nvdia and amd have GPU cores
which are not expensive.  Would we be gaining advantage if we make use
of this hardware?

We have a friend who is willing to write code for it.  I wanted to
know your opinion on this.
