Class Flops

java.lang.Object
  cc.mallet.grmm.util.Flops

public class Flops
extends java.lang.Object

Utilities for flop (floating-point operation) counting. This is a much better way to measure computation than CPU time, because it avoids measuring non-essential properties of the implementations. $Id: Flops.java,v 1.1 2007/10/22 21:37:58 mccallum Exp $
