How to configure an IBERGRID VO

For configuring an IBERGRID VO accessed through user grid interface, follow the following steps:

  1. Configure the iberVO resource. If the grid user interface has defined LCG_GFAL_INFOSYS and MYPROXY_SERVER variables, you do not have to indicate bdii and myproxy_server keys in your configuration:
    [user@mycomputer~]$ drm4g resource edit
    [iberVO]
    enable         = true
    communicator   = local
    username       = user
    frontend       = ui.meteo.unican.es
    lrms           = cream
    vo             = iber.vo.ibergrid.eu
    bdii           = topbdii.egi.cesga.es:2170
    myproxy_server = myproxy.egi.cesga.es
    
    • The communicator will be local or ssh depending on where you have your application is deployed, in your frontend or backend
  2. List and check if the resource has been created successfully :
    [user@mycomputer~]$ drm4g resource list
    RESOURCE            STATE               
    iberVO              enabled
    
  3. Create an identity for 7 days:
    [user@mycomputer~]$ drm4g id iberVO init
    --> Create a local proxy credential ... 
    Insert your Grid password: 
    Your identity: /DC=es/DC=irisgrid/O=unican/CN=user
    Creating proxy ........................................................................................... Done
    Proxy Verify OK
    Your proxy is valid until: Tue Feb 14 12:21:59 2017
    Your identity: /DC=es/DC=irisgrid/O=unican/CN=user
    Creating proxy .................................................................... Done
    Proxy Verify OK
    A proxy valid for 168 hours (7.0 days) for user /DC=es/DC=irisgrid/O=unican/CN=user now exists on myproxy.egi.cesga.es.
    
  4. Check the timeleft of your identity:
    [user@mycomputer~]$ drm4g id iberVO info 
    --> Grid credentials
    subject  : /DC=es/DC=irisgrid/O=unican/CN=user/CN=proxy/CN=proxy
    issuer   : /DC=es/DC=irisgrid/O=unican/CN=user/CN=proxy
    identity : /DC=es/DC=irisgrid/O=unican/CN=user
    type     : full legacy globus proxy
    strength : 2048 bits
    path     : /home/user/.drm4g/security/myproxy.egi.cesga.es
    timeleft : 167:30:49  (7.0 days)
    
  5. List the CEs (Compute Elements) available on the iber.vo.ibergrid.eu VO:
    [user@mycomputer~]$ drm4g host list
    HID ARCH       JOBS(R/T) LRMS       HOST
    0   x86_64           0/0 cream-pbs  iberVO::ce02.up.pt  
    1   x86_64           0/0 cream-pbs  iberVO::ce01.up.pt  
    3   x86_64           0/0 cream-pbs  iberVO::ce03.ific.uv.es
    4   x86_64           0/0 cream-pbs  iberVO::ce01.macc.unican.es
    5   x86_64           0/0 cream-pbs  iberVO::grid001.fc.up.pt
    6   x86_64           0/0 cream-pbs  iberVO::grid001.fe.up.pt
    7   x86_64           0/0 cream-pbs  iberVO::golp-ce.ist.utl.pt
    8   x86_64           0/0 cream-sge  iberVO::ce.ceta-ciemat.es
    9   NULL             0/0 cream-pbs  iberVO::creamce03.ciemat.es
    10  NULL             0/0 cream-pbs  iberVO::creamce02.ciemat.es
    11  x86_64           0/0 cream-sge  iberVO::ce06.ncg.ingrid.pt
    12  x86_64           0/0 cream-sge  iberVO::cream.egi.cesga.es
    

That's it! Now, you can summit jobs to the iber.vo.ibergrid.eu VO. Keep in mind that you will have to renew your identity depending on the proxy-lifetime used.
