Method for packing 8-bit (int8) arrays into GPU memory by Theano
GPU memory is limited. Although NVIDIA TITAN X, which has 12-GB memory, is expensive, sometimes 12 GB is not sufficient. GPU memory is smaller for subordinate GPU models. A numerical value that can be stored in one byte can be stored as an 8-bit integer in GPU memory, and thus the GPU memory is more effectively used. So this article describes a method to do so.
