Detailed Description
template<class Operator1>
struct TMBad::global::RepCompress< Operator1 >
Replicate an operator and apply input compression.
This operator is like global::Rep except that it also represents input compression. Input compression means that the input indices of any given operator can be obtained by adding a constant vector to the inputs of the previous operator.
- Note
- When replacing a batch of binary operators by
RepCompressthe memory reduction is assymptotically2/3(ratio will in general depend on the configuration typedefs).
- Warning
- TO BE DEPRECATED. HAS IMPLICIT DEPENDENCIES.
