  1. GENIUS Grid portalHands on • Moisés Hernández Duarte • UNAM FES Cuautitlán • Tutorial on grid, visualization and high performance calculation • Mexico City, October 23 – 26, 2007 • Based on Luciano Díaz presentation, ICN-UNAM

  2. Outline • Useful information • Exercises • GENIUS logging in and base settings • Launch a job described by a JDL which already exists in the UI • Prepare a job described by a JDL and store it on the UI • Submit the job described by the JDL created in the previous exercise • Preparing a job described by the JDL with a file to ship in the input sandbox • Submitting the job prepared in the previous exercise

  3. Useful information • GENIUS Tutorial website: • https://glite-tutor2.ct.infn.it • Tutorial accounts on glite-tutor: • Username: mexicocityXX where XX goes from 01 to 40 • Password: GridMEXxx where xx goes from 01 to 40 • When issuing the myproxy-init command: • Myproxy password: MEXICOCITY for all the accounts

  4. Introduction: the two-layers Authentication Input password of the user account: mexicocityXX Input password of the proxy (specified when you shall execute myproxy-init) • 1. Authentication with the User Interface • 2. Authentication to the Grid.

  5. Exercise 1 GENIUS logging in and base settings

  6. Outline of the exercise 1/2 • Login at your UI account (passwd: GridMEXxx) • Store a proxy on a remote Myproxy Server machine with the command (using the passphrase MEXICOCITY): • >myproxy-init --voms gilda • Retrieve a local proxy from MyProxy server: • >myproxy-get-delegation(must use your new MyProxy passphrase)

  7. Outline of the exercise 2/2 • Verify your new local proxy: • >voms-proxy-info --all • Destroy your local proxy with the command and then inspect it • >voms-proxy-destroy • Go on the https://glite-tutor2.ct.infn.it with your browser, put your Myproxy passphrase. • Come back on the terminal and execute • >voms-proxy-info --all

  8. >myproxy-init --voms gilda [mexicocity20@eela-132 mexicocity20]$ myproxy-init --voms gilda Cannot find file or dir: /home/mexicocity20/.glite/vomses Your identity: /C=IT/O=GILDA/OU=Personal Certificate/L=MEXICOCITY/CN=MEXICOCITY20/Email=roberto.barbera@ct.infn.it Enter GRID pass phrase: verify OK Creating temporary proxy ................................................... Done Contacting voms.ct.infn.it:15001 [/C=IT/O=GILDA/OU=Host/L=INFN Catania/CN=voms.ct.infn.it/Email=emidio.giorgio@ct.infn.it] "gilda" Done Creating proxy ........................................ Done Your proxy is valid until Sun Sep 3 06:35:26 2006 Enter MyProxy pass phrase: Verifying password - Enter MyProxy pass phrase: A proxy valid for 168 hours (7.0 days) for user mexicocity20 now exists on grid001.ct.infn.it. [mexicocity20@eela-132 mexicocity20]$ Password: MEXICOCITY Choose a new password; This password will be referred later as myproxy password

  9. Get credentials from the MyProxy server • >myproxy-get-delegation • >voms-proxy-info -all [mexicocity20@eela-132 mexicocity20]$ myproxy-get-delegation Enter MyProxy pass phrase: A proxy has been received for user mexicocity20 in /tmp/x509up_u519 [mexicocity20@eela-132 mexicocity20]$ voms-proxy-info -all subject : /C=IT/O=GILDA/OU=Personal Certificate/L=MEXICOCITY/CN=MEXICOCITY20/Email=roberto.barbera@ct.infn.it/CN=proxy/CN=proxy/CN=proxy issuer : /C=IT/O=GILDA/OU=Personal Certificate/L=MEXICOCITY/CN=MEXICOCITY20/Email=roberto.barbera@ct.infn.it/CN=proxy/CN=proxy identity : /C=IT/O=GILDA/OU=Personal Certificate/L=MEXICOCITY/CN=MEXICOCITY20/Email=roberto.barbera@ct.infn.it/CN=proxy/CN=proxy type : unknown strength : 512 bits path : /tmp/x509up_u519 timeleft : 11:51:33 === VO gilda extension information === VO : gilda subject : /C=IT/O=GILDA/OU=Personal Certificate/L=MEXICOCITY/CN=MEXICOCITY20/Email=roberto.barbera@ct.infn.it issuer : /C=IT/O=GILDA/OU=Host/L=INFN Catania/CN=voms.ct.infn.it/Email=emidio.giorgio@ct.infn.it attribute : /gilda/Role=NULL/Capability=NULL timeleft : 11:34:59 [mexicocity20@eela-132 mexicocity20]$

  10. Destroying local voms proxy • >voms-proxy-destroy • >voms-proxy-info -all [mexicocity20@eela-132 mexicocity20]$ voms-proxy-destroy [mexicocity20@eela-132 mexicocity20]$ voms-proxy-info -all Couldn't find a valid proxy. [mexicocity20@eela-132 mexicocity20]$

  11. The Genius Home Page

  12. …then authenticating on GENIUS using myproxy passwd… Myproxy password set before • GRID authentication • The password is the one set when issued the myproxy-init command

  13. Exercise 2 • Launch a job described by a JDL which already exists in the UI • We suppose to have the JDL file and all the other required data (input sandbox files) on the UI and we shall try to submit the job on the GRID

  14. Authentication with MyProxy

  15. GRID Settings

  16. Set VO/VOMS

  17. Selecting jdl file

  18. Specify the CE Resource

  19. Job successfully submitted

  20. Job completed successfully

  21. Retrieving Job results 1/3

  22. Retrieving Job results 2/3

  23. Retrieving job results 3/3

  24. Exercise 3 • Prepare a job described by a JDL and store it on the UI • In this exercise we are going to create a new file on the UI called helloworld.jdl describing a simple job

  25. First step: create the JDL file [ JobType = "Normal"; Executable = "/bin/echo"; Arguments = "Hello World !"; StdOutput = "std.out"; StdError = "std.err"; OutputSandbox = {"std.out","std.err"}; ]

  26. The JDL is ready to be executed

  27. Inspecting our JDL

  28. Exercise 4 • Submit the job described by the JDL created in the previous exercise • In this exercise we are going to submit the job described by the JDL file edited in the previous step

  29. Select JDL file 1/3

  30. Submitting the JDL 2/3

  31. Retrieving job results 3/3

  32. Exercise 5 • Preparing a job described by the JDL with a file to ship in the input sandbox • In this exercise we are going prepare the JDL description for a job which executes a shell script. The .sh file will be shipped to the CE through the input sandbox

  33. Step 1: Create the shell script #!/bin/sh MY_NAME="Your name" WORKER_NODE_NAME=glite-tutor.ct.infn.it echo "Hello $MY_NAME, from $WORKER_NODE_NAME" ls -a echo "This job is running on this CE: " /opt/edg/bin/edg-brokerinfo getCE

  34. Step2: create the JDL file [ Executable = "startScript.sh"; StdOutput = "std.out"; StdError = "std.err"; VirtualOrganisation = "gilda"; InputSandbox = {"startScript.sh"}; OutputSandbox = {"std.out","std.err",".BrokerInfo"}; RetryCount = 7; ]

  35. Exercise 6 • Submitting the job prepared in the previous exercise • In this exercise we are going submit the job which executes a shell script, prepared in the previous exercise. The .sh file will be shipped to the CE through the input sandbox

  36. Submitting job

  37. Retrieving the results
