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

Modifier and Type	Class and 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	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	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	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	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.
