Dear Andrei,

Currently we are not using NVLink. But it is planed to add support for MPI GPU-Direct which should than use NVLink.

Currently we are not using tensor cores. It is not fully clear if tensor cores will give an advantage. ONe drawback of the tensor cores is that the using fp16. In PIConGPU we use at least fp32 if you not activate fp64 support.
Never the less I think a DGX-1 with V100 is the right system.

Hi,
First of all, let me provide some context: we are considering purchasing a DGX-1 system [1] from Nvidia for PIConGPU and are trying to decide between the P100 and V100 versions.
My question is, would PIConGPU run on the DGX-1 and can it make use of NVLink [2] v2.0?
Also, I'm guessing it can't use the tensor cores in the V100 version of DGX-1?
Regards,
Andrei
