21) Message boards : Number crunching : Gpu App? (Message 1637)
Posted 12 Oct 2016 by fruehwf
Post:
We are preparing GPU application for OpenCL 1.1 or later for AMD Radeon HD 7000 (GCN 1.0) and later graphics cards.

Nvidia cards also support OpenCL 1.1, so your code may also work there. Did you try this already, or at least have plans to do so?


Will the gpu app need double precision?

If so, then the mainstream gaming Nvidias won't be that ideal.

What happened here? between 27.8 and 28.8 the worktime increased 2 times, but same Credit...

On all machines..
