Yes, please remove the ".template" suffix, place SystemML-config.xml in the
current directory and set the property systemml.stats.finegrained to true:
https://github.com/apache/systemml/blob/master/conf/SystemML-config.xml.template#L73

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!
Arijit

Hi Janardhan,

You can get instruction-level statistics with the commit

With initial glance (so please feel free to correct me if I am wrong),
Heavy hitter number 5 corresponds to the expression (t(A) %*% A).
Heavy hitter number 17 corresponds to the expression t(mu) %*% mu.
Heavy hitter number 17 corresponds to the expression (output of instruction
5) / scalar
and so on ...

Janardhan Pulivarthi ---07/21/2017 08:57:00 AM---Hi Mike, I'd like to know
how much expensive this critical code is

Hi Mike,

I'd like to know how much expensive this critical code is

C = (t(A) %*% A)/(N-1) - (N/(N-1))*t(mu) %*% mu;

(at
https://github.com/apache/systemml/blob/master/scripts/algorithms/PCA.dml#L81
)
in the SPARK setting given

  1. 60Kx700 input for A
  2. For a datasize of 28 MB with 100 continuous variable and 1 column
  with numeric label variable

with reference to this comment.(
https://issues.apache.org/jira/browse/SYSTEMML-831?focusedCommentId=15525147&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15525147

)

Thank you,
Janardhan
