Installation Instructions for PBSLibra and PBSLibraWeb (c) 2002 Lahore University of Management Sciences For any questions, comments, suggestions, email: jahanzeb@cmu.edu, nosheen@lums.edu.pk, 02020111@lums.edu.pk, or 02020189@lums.edu.pk WARNING: All reponsibility for events resulting from the use of this software is borne by the end user entirely. For instructions on how to use PBSLibra/PBSLibraWeb, refer to their respective manuals (described in installation instructions). Modifications are given below: PBSLibra -------- When submitting jobs, ensure that jobs are submitted with the -W option: e.g., qsub a.pbs -W estimate=10,deadline=20,budget=30 This will ensure that the required constraints are worked with when running the job. If the -W parameter is ignored, the program will not run exactly like PBS (i.e., without Libra's deadline/budget scheduling algorithm) since the scheduler code has been modified. PBSLibraWeb ----------- When submitting jobs using the web-interface, ensure that the correct/required values of estimate, deadline and budget are given in the required fields. Further, more information may be gotten for jobs submitted from the 'View Job Status' page made specifically for Libra that includes essential job information. Installation Instructions for GridSim-Libra (C) 2002 Lahore University of Management Sciences For any questions, comments, suggestions, email: jahanzeb@cmu.edu, nosheen@lums.edu.pk, 02020111@lums.edu.pk, or 02020189@lums.edu.pk WARNING: All reponsibility for events resulting from the use of this software is borne by the end user entirely. For instructions on how to use GridSim-Libra, refer to their respective manuals (described in installation instructions). Deatils are given below: The experiments to be simulated have to be submitted in the form of a text file whose format is given below. This file must be placed in the 'classes' directory of both GridSim (FIFO) and GridSim (Prop. Share). . . . n 1 l 10322 b 900000 d 15411 t 19 n 1 l 224 b 10000 d 948 t 22 n 1 l 763 b 842 d 1264 t 23 n 1 l 24794 b 900000 d 53768 t 20 . . . n represents the number of gridlets in the experiment, with the value immediately following n being this number l being the length of the gridlets in MI, with the numbers following being these lengths (if n=3 then there should appear three, whitespace separated numbers) b being the budget and the number following being the absolute value of the user's budget d being the deadline, and the number following being the absolutel value of the user's deadline t being the time the user comes in with his experiment, and the number following that being that time (assuming the simulation started at time t=0) Going back to the command prompt, making sure you are still in the 'classes' directory, run the simulation by typing "java GridSimMain" without the "" marks. This will create a number of Microsoft Excel files, one for each experiment and one for each node in the cluster. The format of these files is as follows: The first number in the file represents the Gridlet ID. The second number in the file represents the Gridlet arrival time. The third number in the file represents the Gridlet end time. The fourth number in the file represents the Gridlet's deadline. The fifth number in the file represents the Gridlet's length. The last number in the file represents the node's ID on which the Gridlet ran. The size of the cluster (currently set to 10) has to be specified in the GridSim class, which is in the GridUser.java file by changing the no_of_resources variable. Once this is done, the relevant data can be extracted from the excel files to plot whatever graphs are needed.
