openquake.engine package


openquake.engine.engine module

Engine: A collection of fundamental functions for initializing and running calculations.

exception openquake.engine.engine.MasterKilled[source]

Bases: KeyboardInterrupt

Exception raised when a job is killed manually


Check if there is a newer version of the engine.

  • the calculation mode when called from the engine
  • an empty string when called from the WebUI
  • a message if the running version of the engine is obsolete
  • the empty string if the engine is updated
  • None if the check could not be performed (i.e. github is down)
openquake.engine.engine.create_jobs(job_inis, loglvl, kw)[source]

Create job records on the database (if not already there) and configure the logging.

openquake.engine.engine.expose_outputs(dstore, owner='jenkins', status='complete')[source]

Build a correspondence between the outputs in the datastore and the ones in the database.

Parameters:dstore – datastore
Returns:an array with the receiver ports
openquake.engine.engine.inhibitSigInt(signum, _stack)[source]
openquake.engine.engine.manage_signals(signum, _stack)[source]

Convert a SIGTERM into a SystemExit exception and a SIGINT/SIGHUP into a MasterKilled exception with an appropriate error message.

  • signum (int) – the number of the received signal
  • _stack – the current frame object, ignored
openquake.engine.engine.poll_queue(job_id, poll_time)[source]

Check the queue of executing/submitted jobs and exit when there is a free slot.

openquake.engine.engine.run_calc(job_id, oqparam, exports, log_level='info', log_file=None, **kw)[source]

Run a calculation.

openquake.engine.engine.run_jobs(job_inis, log_level='info', log_file=None, exports='', username='jenkins', **kw)[source]

Run jobs using the specified config file and other options.

  • job_inis (str) – A list of paths to .ini files, or a list of job dictionaries
  • log_level (str) – ‘debug’, ‘info’, ‘warn’, ‘error’, or ‘critical’
  • log_file (str) – Path to log file.
  • exports – A comma-separated string of export types requested by the user.
  • username – Name of the user running the job
  • kw – Extra parameters like hazard_calculation_id and calculation_mode

Look at the number of available workers and update the parameter OqParam.concurrent_tasks.default. Abort the calculations if no workers are available. Do nothing for trivial distributions.


returns: a triple of integers from a version tag
