Hop

Classes in org.apache.sysds.hops used by org.apache.sysds.hops.codegen.template

Class and Description
Hop

Classes in org.apache.sysds.hops used by org.apache.sysds.hops.ipa

Class and Description
FunctionOp This FunctionOp represents the call to a DML-bodied or external function.
Hop

Class and Description
Hop

Classes in org.apache.sysds.hops used by org.apache.sysds.hops.rewrite

Class and Description
AggBinaryOp
AggUnaryOp
BinaryOp
DataGenOp A DataGenOp can be rand (or matrix constructor), sequence, and sample - these operators have different parameters and use a map of parameter type to hop position.
DataOp A DataOp can be either a persistent read/write or transient read/write - writes will always have at least one input, but all types can have parameters (e.g., for csv literals of delimiter, header, etc).
Hop
IndexingOp
LeftIndexingOp
LiteralOp
MemoTable Memoization Table (hop id, worst-case matrix characteristics).
NaryOp The NaryOp Hop allows for a variable number of operands.
ParameterizedBuiltinOp Defines the HOP for calling an internal function (with custom parameters) from a DML script.
ReorgOp Reorg (cell) operation: aij Properties: Symbol: ', rdiag, rshape, rsort 1 Operand (except sort and reshape take additional arguments) Semantic: change indices (in mapper or reducer) NOTE MB: reshape integrated here because (1) ParameterizedBuiltinOp requires name-value pairs for params and (2) most importantly semantic of reshape is exactly a reorg op.
TernaryOp Primary use cases for now, are quantile (<n-1-matrix>, <n-1-matrix>, <literal>): quantile (A, w, 0.5) quantile (<n-1-matrix>, <n-1-matrix>, <scalar>): quantile (A, w, s) interquantile (<n-1-matrix>, <n-1-matrix>, <scalar>): interquantile (A, w, s) Keep in mind, that we also have binaries for it w/o weights.
