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
   [esrVO]
   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 esrVO 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.
