16. Outline Introduction to Taiwan Unigrid How to use Taiwan Unigrid ◦ Login ◦ Upload Program/Data ◦ Create Workflow ◦ Submit ◦ Check Job Status

17. Structure of a workflow sequential execution parallel execution Workflow

18. Create Workflow To execute program, first thing is to create the workflow Then create the Stage Then create the Job and fill in proper job description Now we are ready for workflow submission

19. Edit Workflow Choose EditWorkflow in the left hand site Fill in the workflow name your like and press send

20. Create Stage A new workflow with the specified name will appear in the bottom of all existing workflows Press the edit this flow, a new text field will appear to create new stage with the specified stage name

21. Create job Press add new job of the specified stage to fill in the job description

22. Job Description-1 Scheduler: ◦ Using default ”Condor” JOB name : ◦ The name of this job Job Profile : ◦ This profile determined which machine will be allocated, you can try None, CPU_Bound, or Memory_Bound Run Type : ◦ Choose this wisely according to which kind of your program is Binary Filename : ◦ The filename of your program Argument : ◦ The arguments required by your program

23. Job Description-2 Data Filename: ◦ The input file name if required Note that the specified binary and data file must exist on date storage system before press the submission button Output filename : ◦ If your program generate output files, specify the output file name tell the grid system to transfer the output file back to date storage system while job complete. Number of processors : ◦ Required number of processors Machine Select: ◦ Select machine manually by specify the cluster name and required number of processors

24. Job Description-3 SRB Directory : ◦ It tells the grid where the Binary file and data file located ◦ Choose it always while execute your program Note that if you upload your program/date in a specified folder, please also add the relative path to the binary/date filename textfield ◦ EX. You build xxx directory in storage system and put in the file test.exe,then you must fill in the binary filename as./xxx/test.exe and check the SRB directory checkbox

25. Outline Introduction to Taiwan Unigrid How to use Taiwan Unigrid ◦ Login ◦ Upload Program/Data ◦ Create Workflow ◦ Submit ◦ Check Job Status

26. Submit Workflow Select the function Workflow Find out the workflow by the workflow name then press the submit

27. Outline Introduction to Taiwan Unigrid How to use Taiwan Unigrid ◦ Login ◦ Upload Program/Data ◦ Create Workflow ◦ Submit ◦ Check Job Status

28. Check Job Status Choose function Job Status You can see all the submitted workflows as a tree structure in the JobStatus page by ascending order of submit time. The detailed job result will show on the right side.

29. Job Result Description Job name ◦ The same as you specified in workflow Job ID ◦ A unique ID for each job Executable name ◦ The program name specified in binary filename field of workflow Job Start/Finish Time ◦ The time that this job actually start execution and end execution Machine List ◦ List the cluster name and number of processor used in this cluster Job Result ◦ The screen output of the program Job Log ◦ Used for debug, don’t care
