NAME¶
ORTE_FILEM - Open RTE MCA File Management (FileM) Framework: Overview of Open
RTE's FileM framework, and selected modules. Open MPI 1.6.5
DESCRIPTION¶
FileM is a utility framework used by OpenRTE for a variety of purposes,
including the transport of checkpoint files, preloading user binaries, and
preloading of user files.
AVAILABLE COMPONENTS¶
Open RTE currently ships with one FileM component:
rsh.
The following MCA parameters apply to all components:
- filem_base_verbose
- Set the verbosity level for all components. Default is 0, or silent except
on error.
rsh FileM Component¶
The
rsh component uses
rcp or
scp to do its file transfers.
This component requires the use of passwordless
rsh or
ssh
between all nodes.
The
rsh component has the following MCA parameters:
- filem_rsh_priority
- The component's priority to use when selecting the most appropriate
component for a run.
- filem_rsh_verbose
- Set the verbosity level for this component. Default is 0, or silent except
on error.
- filem_rsh_rcp
- The program to use to copy files. Generally will be rcp or scp.
- filem_rsh_rsh
- The program used to remotely log into a given machine and remove files.
Generally will be rsh or ssh.
none FileM Component¶
The
none component simply selects no FileM component. All of the FileM
function calls return immediately with ORTE_SUCCESS.
This component is the last component to be selected by default. This means that
if another component is available, and the
none component was not
explicity requested then ORTE will attempt to activate all of the available
components before falling back to this component.
