[1/2] incubator-systemml git commit: [SYSTEMML-1295] Use janino as
default java compiler for code generation
Repository: incubator-systemml
Updated Branches:
refs/heads/master c04f7b0fb -> c45bb41ff
[SYSTEMML-1295] Use janino as default java compiler for code generation
This patch switches the default java compiler for code generation from
javax.tool.JavaCompiler (javac) to org.codehaus.janino.SimpleCompiler
(janino), which is a fast in-memory Java compiler that improved
compilation overhead by 10-20x. In order to avoid additional runtime
dependencies, we now use Janino in Spark execution modes, but Javac
otherwise. Furthermore, Janino only requires a JRE instead of a JDK
which makes it easier to enable codegen by default in the future.

[2/2] incubator-systemml git commit: [SYSTEMML-1418, 1293,
1424] New cost-based codegen plan selection
Posted by mb...@apache.org.
[SYSTEMML-1418,1293,1424] New cost-based codegen plan selection
This patch introduces a new cost-based plan selector for code generation
including an initial cost model, which will become the default plan
selector in the future. The core ideas are (1) to determine partitions,
i.e, maximally connected sub graphs of memo table entries, (2) to
determine potential materialization points (w/ >=2 consumers) per
partition, and (3) to enumerate and cost alternative plans per partition
via a branch and bound algorithm.
Initial end-to-end experiments on L2SVM, MLogreg, and GLM are very
promising as the resulting performance is equivalent or better than both
existing plan selection heuristics (fuse-all, fuse-no-redundancy).
However, this selector is not yet applied by default, because the cost
model needs further validation and the branch and bound pruning
conditions for skipping of subsets of plans are not integrated yet.
