Strange CPU usage #2

Closed ghost closed 7 years ago

ghost commented 8 years ago

Hi, I'm training the neural network using Recsys2015 dataset and I'm facing with an unexpected CPU utilization (see screenshot below):

schermata del 2016-05-06 12-35-01

It seems that CPU cores aren't properly used (only 1 core out of 16 is fully used, the others are mostly spending their time in kernel-related cycles -- red bars). Can you help me with that? I tested my Theano installation and everything works fine, Theano's test script uses all cores at almost 100%.

Thanks!

where's the dataset's url?

hidasib commented 7 years ago

The processor usage issue is probably due Theano calling lots of short BLAS operations.

@arccos2002: Although I have no idea, why the question about the URL of the dataset is in this thread, since you asked so nicely: http://bit.ly/2hv5UGQ
