I just tryed it and it is not executing on device 1 or gpu 2

Myabe I did not configure it correctly I put the following ni my ini

// This sets the CPU affinity for LLR on multi-CPU machines. It defaults to
// -1, which means that LLR can run on an CPU.
cpuaffinity=

// This sets the GPU affinity for CUDA apps on multi-GPU machines. It defaults to
// -1, which means that the CUDA app can run on an GPU.
gpuaffinity=1
