OpenCL multi device memory problem

Question asked by fredriko on Oct 2, 2013

When using OpenCL together with AMD Radeon HD 7990 that is supposed to have 3 GB memory on each of its two GPUs, I can use (nearly) all of the 3 GB when using one GPU but only about half of the total 6 GB in total while using both GPUs.

 

 

I am using separate OpenCL contexts for the devices.

 

Any idea about what can be the problem?
