Limit CPU usage

[gpanikian]

Dear Colleagues,
I am sending you this message to ask you about how I can limit CPU core usage when running GPy library.
I am applying a bootstrap technique for the classifier to evaluate model performance using the standard implementation as:
model = GPy.models.GPClassification(X=X_train, Y=Y_train, kernel=kernel )
The process is consuming all resources, I tried to set n_jobs or n_workers but I did not succeed doing it!

Can you please help me!

Thank you
Garo

I should also inform you that I tried to limit the number of threads to 2 but there was not any improvement.
Your help is much appreciated!

import os

Limit number of threads to 2

os.environ["OMP_NUM_THREADS"] = "2"
os.environ["OPENBLAS_NUM_THREADS"] = "2"
os.environ["MKL_NUM_THREADS"] = "2"
os.environ["VECLIB_MAXIMUM_THREADS"] = "2"
os.environ["NUMEXPR_NUM_THREADS"] = "2"
