Class MeterVirialBinMultiThreaded

java.lang.Object

etomica.virial.MeterVirialBinMultiThreaded

All Implemented Interfaces:

IAction

public class MeterVirialBinMultiThreaded
extends java.lang.Object
implements IAction

Measures cluster averages for virial coefficients. Configurations are classified by a "property" (an array of ints) and assigned a bin. The average value and standard deviation within that bin is tracked. If a bin has a small standard deviation, its configurations may be skipped (not measured) in order to spend more time on other bins, or to track how often each bin is visited. Additionally, this class can be used in a threaded simulation. Each thread runs a separate simulation, sharing a Map of MyData. This class ensures that the various instances of the meter do not concurrently use the Map in a way that causes problems. Many of the operations need only be approximate and the class avoids forcing synchronization for such operations.
