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

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

Modifier and Type	Class and Description
class	RewriteAlgebraicSimplificationDynamic Rule: Algebraic Simplifications.
class	RewriteAlgebraicSimplificationStatic Rule: Algebraic Simplifications.
class	RewriteBlockSizeAndReblock Rule: BlockSizeAndReblock.
class	RewriteCommonSubexpressionElimination Rule: CommonSubexpressionElimination.
class	RewriteConstantFolding Rule: Constant Folding.
class	RewriteElementwiseMultChainOptimization Prerequisite: RewriteCommonSubexpressionElimination must run before this rule.
class	RewriteGPUSpecificOps
class	RewriteIndexingVectorization Rule: Indexing vectorization.
class	RewriteInjectSparkPReadCheckpointing Rule: BlockSizeAndReblock.
class	RewriteMatrixMultChainOptimization Rule: Determine the optimal order of execution for a chain of matrix multiplications Solution: Classic Dynamic Programming Approach: Currently, the approach based only on matrix dimensions Goal: To reduce the number of computations in the run-time (map-reduce) layer
class	RewriteMatrixMultChainOptimizationSparse Rule: Determine the optimal order of execution for a chain of matrix multiplications Solution: Classic Dynamic Programming Approach: Currently, the approach based only on matrix dimensions and sparsity estimates using the MNC sketch Goal: To reduce the number of computations in the run-time (map-reduce) layer
class	RewriteRemoveDanglingParentReferences This rewrite is a general-purpose cleanup pass that removes any dangling parent references in one pass through the hop DAG.
class	RewriteRemovePersistentReadWrite This rewrite is a custom rewrite for JMLC in order to replace all persistent reads and writes with transient reads and writes from the symbol table.
class	RewriteRemoveReadAfterWrite Rule: RemoveReadAfterWrite.
class	RewriteRemoveUnnecessaryCasts Rule: RemoveUnnecessaryCasts.
class	RewriteTransientWriteParentHandling Rule: Eliminate for Transient Write DataHops to have no parents Solution: Move parent edges of Transient Write Hop to parent of its child Reason: Transient Write not being a root messes up analysis for Lop's to Instruction translation (according to Amol)
