Constructor Detail

PMMJ

public PMMJ(Lop pminput,
            Lop rightinput,
            Lop nrow,
            Types.DataType dt,
            Types.ValueType vt,
            boolean partitioned,
            boolean emptyBlocks,
            Types.ExecType et)

Constructor to setup a Permutation Matrix Multiplication

Parameters:

pminput - permutation matrix input lop

rightinput - right lop

nrow - number of rows?

dt - data type

vt - value type

partitioned - true if partitioned

emptyBlocks - true if output empty blocks

et - execution type

Method Detail

toString

public String toString()

Description copied from class: Lop

Method to have Lops print their state. This is for debugging purposes.

Specified by:

toString in class Lop

getBroadcastInput

public Lop getBroadcastInput()

Description copied from class: Lop

Method to get the input to be broadcast. This method is overridden by the Lops which require broadcasts (e.g. AppendM)

Overrides:

getBroadcastInput in class Lop

Returns:

An input Lop or Null

getInstructions

public String getInstructions(String input_index1,
                              String input_index2,
                              String input_index3,
                              String output_index)

Description copied from class: Lop

Method should be overridden if needed

Overrides:

getInstructions in class Lop

Parameters:

input_index1 - input 1

input_index2 - input 2

input_index3 - input 3

output_index - output

Returns:

instructions as string

setNumThreads

public void setNumThreads(int k)
