### Uses of MultiThreadedHop in org.apache.sysds.hops

Subclasses of MultiThreadedHop in org.apache.sysds.hops
`class` `AggBinaryOp`
`class` `AggUnaryOp`
`class` `BinaryOp` Binary (cell operations): aij + bij Properties: Symbol: *, -, +, ...
`class` `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.
`class` `DnnOp`
`class` `FunctionOp` This FunctionOp represents the call to a DML-bodied or external function.
`class` `ParameterizedBuiltinOp` Defines the HOP for calling an internal function (with custom parameters) from a DML script.
`class` `QuaternaryOp` Note: this hop should be called AggQuaternaryOp in consistency with AggUnaryOp and AggBinaryOp; however, since there does not exist a real QuaternaryOp yet - we can leave it as is for now.
`class` `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.
`class` `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.
`class` `UnaryOp`
