NAME
globus_gram_job_manager_script_interface - Job Manager Scheduler
Interface The GRAM Job Manager interfaces with the job filesystems and
scheduler through scheduler-specific Perl modules.
GRAM provides several Perl modules which can be used to implement
scheduler-specific interfaces to the GRAM Job Manager. These are:
Globus::GRAM::Error
This module implements the GRAM error results as objects. Methods
in this module will construct a GRAM error with the value matching
the values in the GRAM Protocol library. A scheduler-specific
JobManager module may return one of these objects from its methods
to indicate errors to the Job Manager program.
Globus::GRAM::JobState
This module defines the GRAM job state constants. A scheduler-
specific JobManager module returns one of these values from its
methods to indicate the managed job’s current state.
Globus::GRAM::JobSignal
This module defines the GRAM job signal constant values. The Job
Manager uses these values to communicate which signal is being
invoked in the manager’s signal method.
Globus::GRAM::JobManager
This module defines the actual implementatoin of the Job Manager
scheduler interface. One writing a scheduler-specific GRAM
interface will create a subclass of this object which overrides the
default implementation’s methods.
Globus::GRAM::JobDescription
This module mimics the RSL job description using perl syntax. The
job manager passes an object of this type to the JobManager
modules’s constructor. The job manager stores RSL and some
configuration values in that JobDescription object. The manager
accesses values stored in the JobDescription by invoking methods
containing the RSL attribute’s name (example:
$description->gram_my_job()). Method names are handled as if they
were based on the canonical RSL representation of the attribute
name. For example, the gram_my_job may be equivalently referred to
as GramMyJob, grammyjob, or GRAM_My_Job.
