Field Detail

SIMULATION_TIME

public static final long SIMULATION_TIME

SIMULATION_TIME is the approximate total time for the simulation.

LOAD_FACTOR

public static final double LOAD_FACTOR

LOAD_FACTOR is the fraction of time that is spent for accesses. This number must be positive. It is usually less than 1.0

ACCESS_TIME

public static final double ACCESS_TIME

ACCESS_TIME is the read and write access time for a SharedData object. This constant must be positive.

NUM_READERS

public static final int NUM_READERS

NUM_READERS is the number of readers used in the simulation. This number must be a positive integer.

NUM_WRITERS

public static final int NUM_WRITERS

NUM_WRITERS is the number of writers used in the simulation. This number must be a positive integer.

READ_LOAD

public static final double READ_LOAD

READ_LOAD is the fraction of total access time that is spent for Reader accesses. This number must be positive and less than 1.0.

WRITE_LOAD

public static final double WRITE_LOAD

WRITE_LOAD is the fraction of total access time that is spent for Reader accesses. This constant should not be modified.

READ_TWIDDLE

public static final double READ_TWIDDLE

READ_TWIDDLE is the average time that readers spend between reads. This constant should not be modified.

WRITE_TWIDDLE

public static final double WRITE_TWIDDLE

WRITE_TWIDDLE is the average time that writers spend between writes. This constant should not be modified.
