Instance Method Details

#delete(id) ⇒ void

This method is abstract.

Subclass is expected to implement #delete

This method returns an undefined value.

Delete the submitted job

Parameters:

  • id (#to_s) —

    the id of the job

Raises:

  • (NotImplementedError) —

    if subclass did not define #delete

def delete(id)
  raise NotImplementedError, "subclass did not define #delete"
end

#hold(id) ⇒ void

This method is abstract.

Subclass is expected to implement #hold

This method returns an undefined value.

Put the submitted job on hold

Parameters:

  • id (#to_s) —

    the id of the job

Raises:

  • (NotImplementedError) —

    if subclass did not define #hold

def hold(id)
  raise NotImplementedError, "subclass did not define #hold"
end

#info(id) ⇒ Info

This method is abstract.

Subclass is expected to implement #info

Retrieve job info from the resource manager

Parameters:

  • id (#to_s) —

    the id of the job

Returns:

  • (Info) —

    information describing submitted job

Raises:

  • (NotImplementedError) —

    if subclass did not define #info

def info(id)
  raise NotImplementedError, "subclass did not define #info"
end

#info_all(attrs: nil) ⇒ Array<Info>

This method is abstract.

Subclass is expected to implement #info_all

Retrieve info for all jobs from the resource manager

Parameters:

  • attrs (Array<symbol>) (defaults to: nil) —

    defaults to nil (and all attrs are provided) This array specifies only attrs you want, in addition to id and status. If an array, the Info object that is returned to you is not guarenteed to have a value for any attr besides the ones specified and id and status.

    For certain adapters this may speed up the response since adapters can get by without populating the entire Info object

Returns:

  • (Array<Info>) —

    information describing submitted jobs

Raises:

  • (NotImplementedError) —

    if subclass did not define #info_all

def info_all(attrs: nil)

end

#info_all_each(attrs: nil) {|Info| ... } ⇒ Enumerator

Iterate over each job Info object

Parameters:

  • attrs (Array<symbol>) (defaults to: nil) —

    defaults to nil (and all attrs are provided) This array specifies only attrs you want, in addition to id and status. If an array, the Info object that is returned to you is not guarenteed to have a value for any attr besides the ones specified and id and status.

    For certain adapters this may speed up the response since adapters can get by without populating the entire Info object

Yields:

  • (Info) —

    of each job to block

Returns:

  • (Enumerator) —

    if no block given

  info_all(attrs: attrs).each do |job|
    yield job
  end
end

#info_where_owner(owner, attrs: nil) ⇒ Array<Info>

Retrieve info for all jobs for a given owner or owners from the resource manager

Parameters:

  • owner (#to_s, Array<#to_s>) —

    the owner(s) of the jobs

  • attrs (Array<symbol>) (defaults to: nil) —

    defaults to nil (and all attrs are provided) This array specifies only attrs you want, in addition to id and status. If an array, the Info object that is returned to you is not guarenteed to have a value for any attr besides the ones specified and id and status.

    For certain adapters this may speed up the response since adapters can get by without populating the entire Info object

Returns:

  • (Array<Info>) —

    information describing submitted jobs

def info_where_owner(owner, attrs: nil)
  owner = Array.wrap(owner).map(&:to_s)

  # must at least have job_owner to filter by job_owner
  attrs = Array.wrap(attrs) | [:job_owner] unless attrs.nil?

  info_all(attrs: attrs).select { |info| owner.include? info.job_owner }
end

#info_where_owner_each(owner, attrs: nil) {|Info| ... } ⇒ Enumerator

Iterate over each job Info object

Parameters:

  • owner (#to_s, Array<#to_s>) —

    the owner(s) of the jobs

  • attrs (Array<symbol>) (defaults to: nil) —

    defaults to nil (and all attrs are provided) This array specifies only attrs you want, in addition to id and status. If an array, the Info object that is returned to you is not guarenteed to have a value for any attr besides the ones specified and id and status.

#release(id) ⇒ void

This method is abstract.

Subclass is expected to implement #release

This method returns an undefined value.

Release the job that is on hold

Parameters:

  • id (#to_s) —

#status(id) ⇒ Status

This method is abstract.

Subclass is expected to implement #status

Note:

Optimized slightly over retrieving complete job information from server

Retrieve job status from resource manager

Parameters:

  • id (#to_s) —

    the id of the job

Returns:

Raises:

  • (NotImplementedError) —

    if subclass did not define #status

#submit(script, after: [], afterok: [], afternotok: [], afterany: []) ⇒ String

This method is abstract.

Subclass is expected to implement #submit

Submit a job with the attributes defined in the job template instance

Examples:

Submit job template to cluster

solver_id = job_adapter.submit(solver_script)
#=> "1234.server"

Submit job that depends on previous job

post_id = job_adapter.submit(
  post_script,
  afterok: solver_id
)
#=> "1235.server"

Parameters:

  • script (Script) —

    script object that describes the script and attributes for the submitted job

  • after (#to_s, Array<#to_s>) (defaults to: []) —

    this job may be scheduled for execution at any point after dependent jobs have started execution

  • afterok (#to_s, Array<#to_s>) (defaults to: []) —

    this job may be scheduled for execution only after dependent jobs have terminated with no errors

  • afternotok (#to_s, Array<#to_s>) (defaults to: []) —

    this job may be scheduled for execution only after dependent jobs have terminated with errors

  • afterany (#to_s, Array<#to_s>) (defaults to: []) —

    this job may be scheduled for execution after dependent jobs have terminated

Returns:

  • (String) —

    the job id returned after successfully submitting a job

Raises:

  • (NotImplementedError) —

    if subclass did not define #submit

end

#supports_job_arrays? ⇒ Boolean

Whether the adapter supports job arrays

Returns:

  • (Boolean) —

    • assumes true; but can be overridden by adapters that

    explicitly do not
