NAME

       opascpall

       (Linux) Copies files or directories from the current system to multiple hosts in the fabric. When copying
       large  directory  trees,  use  the  -t option to improve performance. This option tars and compresses the
       tree, transfers the resulting compressed tarball to each node, and untars it on each node.

       Use this tool for copying data files, operating system files, or applications to  all  the  hosts  (or  a
       subset of hosts) within the fabric.

       NOTE:

       •      This  tool can only copy from this system to a group of systems in the cluster. To copy from hosts
              in the cluster to this host, use opauploadall.

       •      user@ style syntax cannot be used when specifying filenames.

Syntax

       opascpall [-p] [-r] [-f  hostfile] [-h 'hosts'] [-u  user]
       source_file ... dest_file

       opascpall [-t] [-p] [-f  hostfile] [-h 'hosts'] [-u  user]
       [ source_dir [ dest_dir]]

Options

       --help

                 Produces full help text.

       -p

                 Performs copy in parallel on all hosts.

       -r

                 Performs recursive copy of directories.

       -t

                 Performs optimized recursive copy of directories using tar. dest_dir is optional.  If  dest_dir
                 is  not  specified,  it defaults to the current directory name. If both source_dir and dest_dir
                 are omitted, they both default to the current directory name.

       -h hosts

                 Specifies the list of hosts to copy to.

       -f hostfile

                 Specifies the file with hosts in cluster. Default is /etc/opa/hosts file.

       -u user

                 Specifies the user to perform copy to. Default is current user code.

       source_file

                 Specifies the a file or list of source files to copy.

       source_dir

                 Specifies the name of the source directory to copy. If omitted. is used.

       dest_file or dest_dir

                 Specifies the name of the destination file or directory to copy to. If  more  than  one  source
                 file, this must be a directory. If omitted current directory name is used.

Example

       # efficiently copy an entire directory tree

       opascpall -t -p /usr/src/opa/mpi_apps /usr/src/opa/mpi_apps

       # copy a group of files

       opascpall a b c /root/tools/

       # copy to an explicitly specified set of hosts

       opascpall -h 'arwen elrond' a b c /root/tools

       HOSTS='arwen elrond' opascpall a b c /root/tools

Environment Variables

       The following environment variables are also used by this command:

       HOSTS

                 List of hosts; used if -h option not supplied.

       HOSTS_FILE

                 File containing list of hosts; used in absence of -f and -h.

       FF_MAX_PARALLEL

                 When the -p option is used, maximum concurrent operations are performed.
