Uses of IPAPass in org.apache.sysds.hops.ipa

Subclasses of IPAPass in org.apache.sysds.hops.ipa

Modifier and Type	Class	Description
class	IPAPassApplyStaticAndDynamicHopRewrites	This rewrite applies static hop dag and statement block rewrites such as constant folding and branch removal in order to simplify statistic propagation.
class	IPAPassCompressionWorkloadAnalysis	This rewrite obtains workload summaries for all hops candidates amenable for compression as a basis for workload-aware compression planning.
class	IPAPassEliminateDeadCode	This rewrite eliminates unnecessary sub-DAGs that produce transient write outputs which are never consumed subsequently.
class	IPAPassFlagFunctionsRecompileOnce	This rewrite marks functions with loops as recompile once in order to reduce recompilation overhead.
class	IPAPassFlagLoopsRecompileOnce	This rewrite marks loops in the main program as recompile once in order to reduce recompilation overhead.
class	IPAPassFlagNonDeterminism
class	IPAPassForwardFunctionCalls	This rewrite forwards a function call to a function with a simple function call that only consumes function parameters and literals into the original call location.
class	IPAPassInjectOOCTee	Applies OOC tee injection after static/dynamic rewrites in IPA.
class	IPAPassInlineFunctions	This rewrite inlines single statement block functions, which have fewer operations than an internal threshold.
class	IPAPassPropagateReplaceLiterals	This rewrite propagates and replaces literals into functions in order to enable subsequent rewrites such as branch removal.
class	IPAPassPruneUnreachableHops	Prune stale parent links by keeping only parent references reachable from the statement block roots/predicates.
class	IPAPassRemoveConstantBinaryOps	This rewrite identifies binary operations with constant matrices such as X * ones, where ones might be created as a vector of ones before a loop.
class	IPAPassRemoveUnnecessaryCheckpoints	This rewrite identifies and removes unnecessary checkpoints, i.e., persisting of Spark RDDs into a given storage level.
class	IPAPassRemoveUnusedFunctions	This rewrite identifies and removes unused functions in order to reduce compilation overhead and other overheads such as parfor worker creation, where we construct function copies.
class	IPAPassReplaceEvalFunctionCalls	This rewrite applies static hop dag and statement block rewrites such as constant folding and branch removal in order to simplify statistic propagation.
class	IPAPassRewriteFederatedPlan	This rewrite generates a federated execution plan by estimating and setting costs and the FederatedOutput values of all relevant hops in the DML program.
