Converting single-GPU DualSPHysics to double-GPU

Sunil

Hi,

The single node I use has two Nvidia K20X GPU cards. I would like to know how much work is involved in converting the single-node single-GPU DualSPHysics v3.0 code to single-node double-GPU code.

Some ideas on how to split the work between the two GPU's will be helpful.

Do the two GPU's have to communicate with each other ?

Thank you very much,

Best Regards,
Sunil
