Hi, Dear all: I am a little bit confused by the usage of WorkLoad class. 1. Does it provide the workload of a resource/machine, like the information presented in http://www.cs.huji.ac.il/labs/parallel/workload/logs.html ? 2. Or it traces the jobs submitted via same grid user (user's jobs workload trace?), since it's declared as "This class can be classified as one grid user entity" in the comment. 3. What's the type of this traced workload information? Dynamic or statistic? I tried to run the WorkLoadTrace demo codes from sample, however, i always got the following errors: --- Initializing GridSim package Initialising...
