For a input sandbox file that must be staged from the client machine, ss described in the CREAM JDL guide there are 2 possibilities:

  • It can be retrieved from the gridftp/https server running on the client machibne (this file transfer is done when the CREAM jobWrapper starts its execution)
  • It can be first staged in the gridftp server of the CREAM CE (this file transfer is done when the job is submitted to the CE) and then it is staged on the WN (this latter file transfer is done when the CREAM jobWrapper starts its execution)
