[gentoo-user] eselect OpenCL is wrong.

[Alan Grimes]

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.

No reason to go into hysterics. Think of your blood pressure! ;-)

You should better report this to the developers of the respective
applications. I'm not an expert on this, but I think this is nothing 
that the gentoo developers can do.

And I think it's better to have "eselect OpenCL" than nothing.

That's already the case. They're stored in /usr/lib/OpenCL/vendors/. 
eselect just allows applications that don't provide a mechanism for 
selecting an implementation to work.

Not sure what you're asking for here :-/

Okay, nm then. carry on. =P

I was just a bit concerned because sometimes eselect is, necessarily, a
bit more brutal about things.
