LSFExecutor

The LSFExecutor class is responsible for submitting jobs to LSF Scheduler.

Attributes

buildtest.executors.lsf.logger
class buildtest.executors.lsf.LSFExecutor(name, settings, site_configs, account=None, maxpendtime=None, timeout=None)[source]

Bases: buildtest.executors.base.BaseExecutor

The LSFExecutor class is responsible for submitting jobs to LSF Scheduler. The LSFExecutor performs the following steps

  • load: load lsf configuration from buildtest configuration file

  • dispatch: dispatch job to scheduler and acquire job ID

  • poll: wait for LSF jobs to finish

  • gather: Once job is complete, gather job data

Initiate a base executor, meaning we provide a name (also held by the BuildExecutor base that holds it) and the loaded dictionary of config opts to parse.

Parameters:

  • name (str) – name of executor

  • setting (dict) – setting for a given executor defined in configuration file

  • site_configs (buildtest.config.SiteConfiguration) – Instance of SiteConfiguration class

  • timeout (str, optional) – Test timeout in number of seconds

  • maxpendtime (int, optional) – Maximum Pending Time until job is cancelled. The default is 1 day (86400s)

  • account (str, optional) – Account to use for job submission

  • maxpendtime – Maximum Pending Time until job is cancelled. The default is 1 day (86400s)

type = 'lsf'
launcher_command(numprocs=None, numnodes=None)[source]

This command returns the launcher command and any options specified in configuration file. This is useful when generating the build script in the BuilderBase class

run(builder)[source]

This method is responsible for dispatching job to scheduler and extracting job ID by applying a re.search against output at onset of job submission. If job id is not retrieved due to job failure or unable to match regular expression we mark job incomplete by invoking buildtest.buildsystem.base.BuilderBase.incomplete`() method and return from method.

If we have a valid job ID we invoke buildtest.executors.lsf.LSFJob class given the job id to poll job and store this into builder.job attribute.

Parameters:

builder (buildtest.buildsystem.base.BuilderBase) – An instance object of BuilderBase type
