Subject: Re: --fork using different OpenCL devices

> The idea is to have -fork pick a different device (starting from 0 or picking from a given list) for each child. Picture having two 7990 cards for a total of four devices. Using "-fork=4" with an OpenCL format would pick device 0 for the mother process, device 1 for first child and so on. Only very fast formats [where set_key() is a bottleneck] would benefit.

What would be the speed of slower+faster device combination? 2*slower?
For homogenous system it is good solution anyway.
