Re: Proof Asynchronous Mode

    Hello,

    Yes, the workers must be able to open the files, either from a shared file system, or from a server

    (http://, root://, ...) or from a local file system.

    in the specific case the files are available at

        http://root.cern.ch/files/h1

    so you can create the chain with the macro under tutorials/tree

      root [] .x
$ROOTSYS/tutorials/tree/h1chain.C("http://root.cern.ch/files/h1")

   and your problem should go away.

   In the general case, files are read out from ad hoc servers, typically based on xrootd, some tool is used

   to populate the local disks on the machines. For example, the dataset manager daemon under

   $ROOTSYS/proof/afdsmgrd can be used in conjunction with xrootd to do that (see also

   http://code.google.com/p/afdsmgrd/).
