----------------------------------------
Summary: 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
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.
