Please note that it is not necessary to have multiple distributed workers to exploit several CPU cores (every worker spawns several threads anyway).

Originally posted by @jonathan-laurent in #18 (comment)

I can see on my platform monitoring that during training, only 1 vCPU out of 8 is used. Apart from setting num_workers parameters in params.jl (which I left at the default value of 128 for all occurrences), is there something to be done in order to effectively use multiple cores?

Several CPU cores should be used automatically if you start Julia with -t 8 or sets JULIA_NUM_THREADS to 8.
