[jira] [Commented] (SYSTEMML-845) Compare Performance of LeNet
Scripts With & Without Using SystemML-NN
[ https://issues.apache.org/jira/browse/SYSTEMML-845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15408502#comment-15408502 ]
Mike Dusenberry commented on SYSTEMML-845:
------------------------------------------
[~niketanpansare] When running in forced singlenode mode, these two scripts have equal performance (time & accuracy). However, I'm seeing severe regressions when attempting to run with Spark (--master local[*], 50G driver memory), or even just standalone mode with hybrid-mr mode. For example, I limited the {{epochs}} in both scripts to just 2, and then ran with {{-explain}} and {{-stats}}, and it showed a very large number of Spark jobs (as well as MR jobs in the hybrid-mr mode). The logs are too large to include. Looking through the explain plan, it looks like many operations are being mapped to Spark jobs in both scripts. Any thoughts?

> This JIRA issue tracks the comparison of the performance of the LeNet scripts with & without using SystemML-NN. The goal is that they should have equal performance in terms of both accuracy and time. Any difference will be indicate areas of engine improvement.
> Scripts:
> * [mnist_lenet-train.dml | https://github.com/apache/incubator-systemml/blob/master/scripts/staging/SystemML-NN/examples/mnist_lenet-train.dml] - LeNet script that *does* use the SystemML-NN library.
> * [lenet-train.dml | https://github.com/apache/incubator-systemml/blob/master/scripts/staging/lenet-train.dml] - LeNet script that *does not* use the SystemML-NN library.
