Glenn Weidner updated SYSTEMML-1882: ------------------------------------ Fix Version/s: (was: SystemML 1.0) SystemML 0.15 > Perftest: Kmeans shows different behavior compared to previous releases > ----------------------------------------------------------------------- > > Key: SYSTEMML-1882 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1882 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Priority: Blocker > Fix For: SystemML 0.15 > > > The current SystemML master shows different convergence behavior on the > perftest Kmeans scenarios. Triggered by significantly increased execution > times, a comparison with 0.14 showed the following output (note the different > number of iterations): > With SystemML 0.14 > {code} > Run 1, Iteration 1: Terminated with code = 3, Centroid WCSS = > 1.1884874830960146E11 > Run 3, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 2, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 7, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 6, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 9, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 8, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 4, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 5, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > Run 10, Iteration 2: Terminated with code = 1, Centroid WCSS = > 1.1836165397662901E11 > {code} > With SystemML master: > {code} > Run 8, Iteration 12: Terminated with code = 1, Centroid WCSS = > 1.0897515693466766E11 > Run 4, Iteration 14: Terminated with code = 1, Centroid WCSS = > 1.0900183622869571E11 > Run 1, Iteration 15: Terminated with code = 1, Centroid WCSS = > 1.0892913262046584E11 > Run 2, Iteration 16: Terminated with code = 1, Centroid WCSS = > 1.0893145533814377E11 > Run 6, Iteration 17: Terminated with code = 1, Centroid WCSS = > 1.0881596327984634E11 > Run 3, Iteration 17: Terminated with code = 1, Centroid WCSS = > 1.0910103829718127E11 > Run 7, Iteration 20: Terminated with code = 1, Centroid WCSS = > 1.089467832141638E11 > Run 10, Iteration 20: Terminated with code = 2, Centroid WCSS = > 1.0873719552339151E11 > Run 5, Iteration 20: Terminated with code = 2, Centroid WCSS = > 1.0891758743999176E11 > Run 9, Iteration 20: Terminated with code = 2, Centroid WCSS = > 1.089222095610236E11 > {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
