I'm working on Seq2Seq model using LSTM from Keras (using Theano background) and I would like to parallelize the processes, because even few MBs of data need several hours for training.
It is clear that GPUs are far much better in parallelization than CPUs. At the moment, I only have CPUs to work with. I could access 16 CPUs(2 Threads per core X 4 cores per socket X 2 sockets)
From the doc of multi-core support in Theano, I managed to use all the four cores of a single socket. So, basically the CPU is at 400% usage with 4CPUs used and the remaining 12 CPUs remain unused. How do I make use of them too. Tensorflow could also be used instead of Theano background, if it works.
