Uses of StatementBlockRewriteRule in org.apache.sysds.hops.rewrite

Subclasses of StatementBlockRewriteRule in org.apache.sysds.hops.rewrite

Modifier and Type	Class and Description
class	MarkForLineageReuse
class	RewriteCompressedReblock Rule: Compressed Re block if config compressed.linalg is enabled, we inject compression directions after read of matrices if number of rows is above 1000 and cols at least 1.
class	RewriteForLoopVectorization Rule: Simplify program structure by pulling if or else statement body out (removing the if statement block ifself) in order to allow intra-procedure analysis to propagate exact statistics.
class	RewriteHoistLoopInvariantOperations Rule: Simplify program structure by hoisting loop-invariant operations out of while, for, or parfor loops.
class	RewriteInjectSparkLoopCheckpointing Rule: Insert checkpointing operations for caching purposes.
class	RewriteMarkLoopVariablesUpdateInPlace Rule: Mark loop variables that are only read/updated through cp left indexing for update in-place.
class	RewriteMergeBlockSequence Rule: Simplify program structure by merging sequences of last-level statement blocks in order to create optimization opportunities.
class	RewriteRemoveEmptyBasicBlocks Rule: Simplify program structure by removing empty last-level blocks, which may originate from the original program or due to a sequence of rewrites (e.g., checkpoint injection and subsequent IPA).
class	RewriteRemoveForLoopEmptySequence Rule: Simplify program structure by removing (par)for statements iterating over an empty sequence, i.e., (par)for-loops without a single iteration.
class	RewriteRemoveUnnecessaryBranches Rule: Simplify program structure by pulling if or else statement body out (removing the if statement block ifself) in order to allow intra-procedure analysis to propagate exact statistics.
class	RewriteSplitDagDataDependentOperators Rule: Split Hop DAG after specific data-dependent operators.
class	RewriteSplitDagUnknownCSVRead Rule: Split Hop DAG after CSV reads with unknown size.
