some question of exemplar memory's training time

[yyang-2018]

Thank you for your open source code，In your paper,you analysed the computational cost of the exemplar memory.But when I ran your code,I found It took me more than two hours in my machine. so I want to ask you whether you run on a single GPU or multiple GPUs ? Or do you have any way to reduce the running time? By the way,my machine configuration is a 12G single GPU.

I look forward to your reply，Thank you!
