Matthias Boehm closed SYSTEMML-2017. ------------------------------------ Resolution: Fixed Assignee: Matthias Boehm Fix Version/s: SystemML 1.0 > Missing frame delete from buffer pool on rmvar, cpvar, etc > ---------------------------------------------------------- > > Key: SYSTEMML-2017 > URL: https://issues.apache.org/jira/browse/SYSTEMML-2017 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Fix For: SystemML 1.0 > > > A recent scenario with frame appends and casts in loops revealed a hidden > buffer issues regarding frames. As it turned out, frames are never deleted on > rmvar, cpvar or similar instructions which leads to shrinking buffer pool > size, unnecessary GC and unnecessary evictions. At script level this issue > manifests itself by fast early iterations, but a significant performance hit > as soon as the buffer pool size is reached. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
