Multiple device usage with CuPP

[Dinh]

Hello,

I was wondering if anyone had any success adding multiple device
capability to CuPP? Or any hint on how to go about doing this?

Thank you,

I don't think so -- at least I am not aware of anyone who has done
this. It is on the todo list, but with a rather low priority at the
moment.

The idea is to use GPUworker ( http://forums.nvidia.com/index.php?showtopic=66598
) or something similar as part of cupp::device. All functions
interacting with the device will be put the in the cupp::device work
queue, which will be executed by a separate worker thread.

Thanks,

The reason that I asked is because I have the 9800 GX2. I thought to
cluster many GPUs to make a personal supercomputer.

You are welcome to try, but adding multigpu support will probably take
some time. You may however create two threads and have each use its
own cupp::device and own cupp datastructures, this should(!) work --
however, I haven't tried this till now.
