EGI Grid

Práctica 1

El objetivo de esta práctica es tomar contacto con el uso de recursos de computación grid en la VO tut.vo.ibergrid.eu. Recuerde que estos comandos han de ejecutarse desde el frontend ui.macc.unican.es.

• Generamos un proxy válido para operar en la VO tut.vo.ibergrid.eu:

  [user@ui ~]$ voms-proxy-init -voms tut.vo.ibergrid.eu
  

• Para obtener información del proxy generado ejecute :

  [user@ui ~]$ voms-proxy-info -all
  

• Listamos los recursos computación para ejecutar jobs (Computing Element) :

  [user@ui ~]$ lcg-infosites --vo tut.vo.ibergrid.eu ce
  

• Listamos los recursos de computación de almacenamiento (Storage Element) :

  [user@ui ~]$ lcg-infosites --vo tut.vo.ibergrid.eu se
  

• Una vez listados los recursos, enviaremos un job a uno de los CE listados. Creamos las plantillas necesarias para ejecutar el job :

  [user@ui ~]$ cat > hello.jdl << EOF
  Executable = "hello.sh" ; 
  CpuNumber = 1;
  StdOutput = "stdout.txt";
  StdError = "stderr.txt";
  InputSandbox = {"hello.sh"};
  OutputSandbox = {"stdout.txt", "stderr.txt"};
  Requirements = other.GlueCEUniqueID == "ce.ceta-ciemat.es:8443/cream-sge-ibtut.cg";
  EOF
  [user@ui ~]$ cat > hello.sh << EOF
  #!/bin/sh
  echo "Hello World - from $HOSTNAME"
  echo -n "It's " 
  date
  EOF
  

• Enviamos el job :

  [user@ui ~]$ glite-wms-job-submit -a -o jobid.txt hello.jdl
  

• Comprobamos el estado del job :

  [user@ui ~]$ glite-wms-job-status -i jobid.txt
  

• Una vez el estado del job es Done.

  [user@ui ~]$ glite-wms-job-output -i jobid.txt --dir .
