THCudaCheck FAIL error=2 : out of memory... MultiGPU training

[eugene8568]

Hi,

I try to train the model using command "th train.lua -encoder hre-ques-hist -decoder gen -gpuid 1" . But somehow it shows THCudaCheck FAIL ...error=2 : out of memory. I was able to perform training after I reduced batch size less than 40.

I would like to know how can I utilize two GPU for this training? Kindly advise.
