Constructor Detail

NodeSimulator

public NodeSimulator(double latency,
                     double dynamicOverhead,
                     double speed)

Initialize this simulator with the specified parameters.

Parameters:

latency - static simulated latency.

dynamicOverhead - dynamic overhead expressed as milliseconds per megabyte of data transferred.

speed - relative speed of the node.

Method Detail

run

public void run(Bundler bundler,
                double sizeMB,

Simulate the execution of a set of tasks.

Parameters:

bundler - the bundler to send the resulting statistics to.

sizeMB - the size in megabytes of the data that is transferred.

nbTasks - the number of simulated tasks.

timePerTask - the simulated execution time for each task.

main

public static void main(String... args)

Entry point to test this class.

Parameters:

args - not used.
