Executing a calculation scheme in console mode

A well-configured SALOME installation is necessary to execute a calculation scheme in the XML format in console mode. SALOME execution mode from a SALOME application will be used in the remainder of this document.

  1. run SALOME: ./runAppli-t, for example from the application directory (it can be run from any other directory).
  2. execute the YACS supervisor: ./runSession driver schema.xml
  3. stop SALOME: ./runSession shutdownSalome.py for a clean stop or ./runSession killSalome.py for an immediate stop.

Steps 2 and 3 can be done from inside a SALOME session. YACS can be executed and SALOME can be stopped within this session as follows:

  1. initialise the session: /.runSession
  2. execute the YACS supervisor: driver schema.xml
  3. stop SALOME: shutdownSalome.py or killSalome.py
  4. exit from the session: CTRL+D

The YACS supervisor in console (driver) mode accepts a few options to set parameters for its execution:

Usage: driver [OPTION...] graph.xml
driver -- a SALOME YACS graph executor

  -d, --display=level        Display dot files: 0=never to 3=very often
  -e, --dump-on-error[=file] Stop on first error and dump state
  -f, --dump-final[=file]    dump final state
  -l, --load-state=file      Load State from a previous partial execution
  -s, --stop-on-error        Stop on first error
  -v, --verbose              Produce verbose output
  -x, --save-xml-schema[=file]   dump xml schema
  -?, --help                 Give this help list
      --usage                Give a short usage message
  -V, --version              Print program version

The following gives a few typical uses of the driver.

Standard execution

During a standard execution, the supervisor reads the XML file that describes the scheme, executes it and then produces an error report (see Error report) if necessary:

driver schema.xml

Execution displaying states of nodes during execution

driver --display=1 schema.xml

Execution saving the final state of the scheme

driver --dump-final=mystate.xml schema.xml

Execution loading the initial state of the scheme

driver --load-state=mystate.xml schema.xml
