How to select GPU instead og CPU for parallel calculation?
Hello Iber-Team,

how can I tell Iber+ to use the GPU instead of the CPUs? I have two 6 core Xeon CPUs with activated Hyperthreading and a Nvidia Quadro K6000 GPU installed and active. Iber+ seems to use only the CPUs.
Other applications that use CUDA/OpenCL make use of this GPU.

OS is Win 7 64, GPU driver is NVIDIA 386.07 (22.21.13.8607).

The task manager shows that IberPlus.exe is using 12 threads (50% overall CPU load). GPU-Z shows no load/memory use on the GPU.
My Iber out window gives the following infos:

Iber+ 1.2b (v1.1-18-g2131da7_)
===================================
[...]
Initial volume: 0.00 m3
Numerical scheme: Roe 1st Order
Number of elements: 3572223
Number of boundaries: 10931
Number of edges: 5352869

Using CPU: 12 threads
[...]


It definetively runs parallelized, but not on the GPU;(

Thanks for your support
Axel
