DataGen
public DataGen(Types.OpOpDG op, DataIdentifier id, HashMap<String,Lop> inputParametersLops, String baseDir, Types.DataType dt, Types.ValueType vt, Types.ExecType et)
Creates a new Rand-LOP. The target identifier has to hold the dimensions of the new random object.
- Parameters:
op
- data gen methodid
- target identifierinputParametersLops
- Lops of input parametersbaseDir
- base dir for runtimedt
- Data typevt
- Value typeet
- Execution type

init
public void init(DataIdentifier id, String baseDir, Types.ExecType et)
-
getInstructions
public String getInstructions(String output)
Function to generate CP/SP instructions for data generation via Rand and Seq. Since DataGen Lop can have many inputs, ONLY the output variable name is passed from piggybacking as the function argumentoutput
.- Overrides:
getInstructions
in classLop
- Parameters:
output
- output- Returns:
- instructions as string
-
toString
public String toString()
Description copied from class:Lop
Method to have Lops print their state. This is for debugging purposes.

setNumThreads
public void setNumThreads(int k)
