Wrong, I say, WROOOOONG!!!!! OpenCl is not OpenGL. It is more of a framework than an API. A high end machine may have a number of different OpenCL hosts, the cpu, vector cores built into the cpu as in the AMD APU line and intel's lame knockoff thereof. =P
There is also OpenCL support in GPUs, Xeon Phi, FPGA and potentially other devices too. The game Planet Explorers (available on Steam) demonstrates how this should be used. You are given a menu at the start of the game that lists the available OpenCL implementations. You then select whatever device you want to use for OpenCL that day... So there should not be eselect OpenCL, All gentoo needs to do is enforce standards on where the relevant libraries are stored and the application will select which one to use. -- IQ is a measure of how stupid you feel. Powers are not rights.
