Validation of the Parallel Simulator The output log for this simulation model can be found in Appendix F. A comparison of the original simulation model file and the in memory object structure representation that was output by the simulator shows that they are equivalent and that the parser correctly parsed all lines of the simulation model. Validation 1.2 The simulation model for this validation is based on the earlier simulation model but all optional elements of the model were removed. STORAGE Storage1 GENERATE ENTER Storage1 ADVANCE LEAVE Storage1 TRANSFER Label1 TERMINATE PARTITION Partition2 Label1 QUEUE Queue1 DEPART Queue1 SEIZE Facility1 RELEASE Facility1 TERMINATE Simulation model file model_validation1.2.gps As described this simulation model tests the parser regards setting default values for optional elements and parameters. Comparing the simulation model file to corresponding output log in Appendix F it can be found that the parser automatically created a new partition before parsing the first line of the model so that the in memory representation of the model contains two partitions (see line 2 of output log). The default name given to this partition by the parser is ‘Partition 1’ (see line 6 of output log). Line 9 shows that the Storage size was set to its maximum value of 2147483647. The GENERATE block at line 10 was parsed with all its parameters set to its default values as described in Appendix A. This also applies to the ADVANCED block at line 12 and the TERMINATE blocks at line 15 and 27 of the output log. The usage count of the ENTER and LEAVE block at the lines 11 and 13 were set to the expected default value of 1 and the TRANSFER block at line 14 of the output log also has the default transfer probability of 1 so that all Transactions would be transferred to the specified 77
78 Validation of the Parallel Simulator label. It can be seen that all the missing parameters were set to their expected default values. 6.2 Validation 2 This validation evaluates the basic GPSS functionality of the parallel simulator. This includes the basic scheduling and the movement of Transactions as well as the correct processing of the GPSS blocks. The simulation model used for this contains only a single partition but otherwise all possible GPSS block types and entities. There is even a TRANSFER block that transfers Transactions with a probability of 0.5. The model is shown below: PARTITION Partition1,4 STORAGE Storage1,2 GENERATE 3,2 QUEUE Queue1 ENTER Storage1,1 ADVANCE 5,3 LEAVE Storage1,1 DEPART Queue1 TRANSFER 0.5,Label1 SEIZE Facility1 RELEASE Facility1 Label1 TERMINATE 1 Simulation model file model_validation2.gps The model is simulated with the log4j loggers parallelJavaGpssSimulator.simulation and parallelJavaGpssSimulator.gpss set to DEBUG (see configuration file proactive- log4j at the corresponding sub folder on the attached CD). The last of these two loggers will result in a very detailed logging of the GPSS processing and Transaction movement. For this reason the Termination Counter is kept very small, i.e. set to 4 so that the simulation is stopped after 4 Transactions have been terminated. Otherwise the output log would be too long to be useful. The deployment descriptor XML file is set to a single ProActive node as the model contains exactly one partition and the simulation will require only one LP.
