aoa() and calibrate_aoa() with parallelization

[daniel-althoff]

Hi,

I have been using the AOA() function with parallelization as follows:

´´´
cl <- makePSOCKcluster(detectCores()-2)
registerDoParallel(cl)
AOA <- aoa(df, model_sp, cl)
stopCluster(cl)
´´´

When I check the task manager processes and performance tabs, it doesn't seem like the computer is using its cores. CPU usage is quite low (below 20%), and it takes quite some time to finish.
(dataset: 70.000 lines, 17 columns, 10folds 5reps cv)
Any idea on what might be happening? :)

In addition, I tried using the calibrate_aoa() function with multiCV=T, it took days and ended up throwing an error in the end. I'll run it again when I have some time and post the message.
