Multi GPUs not working

[doantientai]

I'm trying to run pix2pix network with 2 GPU with option
--gpu_ids 0,1
However only one GPU is running.
I have 2 GPUs both are Titan 6GB

Oh, I realized that I used default batchSize which is 1. Now I increased it up to 100 and both GPUs are working very well.
