| FunctionCallGraph |
|
| FunctionCallSizeInfo |
Auxiliary data structure to hold function call summaries in terms
of information about number of function calls, consistent dimensions,
consistent sparsity, and dimension-preserving functions.
|
| InterProceduralAnalysis |
This Inter Procedural Analysis (IPA) serves two major purposes:
1) Inter-Procedure Analysis: propagate statistics from calling program into
functions and back into main program.
|
| IPAPass |
Base class for all IPA passes.
|
| IPAPassApplyStaticAndDynamicHopRewrites |
This rewrite applies static hop dag and statement block
rewrites such as constant folding and branch removal
in order to simplify statistic propagation.
|
| IPAPassCompressionWorkloadAnalysis |
This rewrite obtains workload summaries for all hops candidates amenable for compression as a basis for
workload-aware compression planning.
|
| IPAPassEliminateDeadCode |
This rewrite eliminates unnecessary sub-DAGs that produce
transient write outputs which are never consumed subsequently.
|
| IPAPassFlagFunctionsRecompileOnce |
This rewrite marks functions with loops as recompile once
in order to reduce recompilation overhead.
|
| IPAPassFlagNonDeterminism |
|
| 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.
|
| IPAPassInlineFunctions |
This rewrite inlines single statement block functions, which have fewer
operations than an internal threshold.
|
| IPAPassPropagateReplaceLiterals |
This rewrite propagates and replaces literals into functions
in order to enable subsequent rewrites such as branch removal.
|
| 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.
|
| IPAPassRemoveUnnecessaryCheckpoints |
This rewrite identifies and removes unnecessary checkpoints, i.e.,
persisting of Spark RDDs into a given storage level.
|
| 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.
|
| IPAPassReplaceEvalFunctionCalls |
This rewrite applies static hop dag and statement block
rewrites such as constant folding and branch removal
in order to simplify statistic propagation.
|
| 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.
