option to increase num threads

[alhafidzhamdan]

Hi there when I run driverpower model is there a way to allow for increased cores used ? at the moment it seems to just run at 8.

Hi @alhafidzhamdan,

I'm wondering if you are talking about the modelling step as it's the most time-consuming step? The GBM by default uses 15 cores if my memory is correct and can be configured via xgboost's configuration file, while the GLM can be multi-threaded but not implemented yet.

Hi there, thanks for getting back to me. I was just testing the example data using this command:

driverpower model
--feature train_feature.hdf5
--response train_y.tsv
--method GBM
--name tutorial
--modelDir ./output

As part of the log it says

05/31/2020 16:27:30 | INFO: Note: NumExpr detected 32 cores but "NUMEXPR_MAX_THREADS" not set, so enforcing safe limit of 8.

So I was wondering if there was any way to change the threads?
