Thanks, Niketan Pansare IBM Almaden Research Center E-mail: npansar At us.ibm.com http://researcher.watson.ibm.com/researcher/view.php?person=us-npansar From: arijit chakraborty <ak...@hotmail.com> To: "dev@systemml.apache.org" <dev@systemml.apache.org> Date: 07/21/2017 12:21 PM Subject: RE: about performance statistics of PCA.dml Hi Niketan, Sorry to get in between you and Janardhan’s chat. Actually I’m having issue in improving the performance of my system. You suggested me how to get some stats and I’ve incorporated it. But things after “Heavy hitter instructions:”, seems very useful for me to debug where the system is taking too much time. So can you suggest me how to print out reports you are getting after “Heavy hitter instructions:”. Do we need to make any changes in any of the config file? Thank you!
