# yade-batch(1)

manual page for Using python version: 3.13.2 (main, Mar 13 2025, 14:29:07) \[GCC 14.2.0\]

## NAME

Using - manual page for Using python version: 3.13.2 (main, Mar 13 2025, 14:29:07) \[GCC 14.2.0\]

## DESCRIPTION

Using python version: 3.13.2 (main, Mar 13 2025, 14:29:07) \[GCC 14.2.0\] usage: yade-double-batch \[options\] \[ TABLE \[SIMULATION.py\] \| SIMULATION.py\[/nCores\] \[...\] \]

yade-double-batch runs yade simulation multiple times with different parameters. See https://yade-dem.org/sphinx/user.html#batch-queuing-andexecution-yade-batch for details. Batch can be specified either with parameter table TABLE (must not end in .py), which is either followed by exactly one SIMULATION.py (must end in .py), or contains !SCRIPT column specifying the simulation to be run. The second option is to specify multiple scripts, which can optionally have */nCores* suffix to specify number of cores for that particular simulation (corresponds to !THREADS column in the parameter table), e.g. sim.py/3.

### options:

- **-h**, **--help**

  show this help message and exit

- **-j**, **--jobs** NUM

  Maximum number of simultaneous threads to run (default: number of cores, further limited by OMP\_NUM\_THREADS if set by the environment: 6)

- **-v**, **--version**

  Print version and exit.

- **--job-threads** NUM

  Default number of threads for one job; can be overridden by per-job with !THREADS (or !OMP\_NUM\_THREADS) column. Defaults to 1.

- **--force-threads**

  Force jobs to not use more cores than the maximum (see \\-j), even if !THREADS colums specifies more.

- **--log** FORMAT

  Format of job log files: must contain a $, % or @, which will be replaced by script name, line number or by description column respectively (default: $.@.log)

- **--global-log** FILE

  Filename where to redirect output of yade-batch itself (as opposed to \\-\\-log); if not specified (default), stdout/stderr are used

- **-l**, **--lines** LIST

  Lines of TABLE to use, in the format 2,3-5,8,11-13 (default: all available lines in TABLE)

- **--nice** NICE

  Nice value of spawned jobs (default: 10)

- **--cpu-affinity**

  Bind each job to specific CPU cores; cores are assigned in a quasi-random order, depending on availability at the moment the jobs is started. Each job can override this setting by setting AFFINE column.

- **--executable** FILE

  Name of the program to run (default: */build/reproduciblepath/yade-2025.2.0/debian/tmp/usr/bin/yade-double*). Jobs can override with !EXEC column.

- **--gnuplot** FILE

  Gnuplot file where gnuplot from all jobs should be put together

- **--dry-run**

  Do not actually run (useful for getting gnuplot only, for instance)

- **--http-wait**

  Do not quit if still serving overview over http repeatedly

- **--plot-update** TIME

  Interval (in seconds) at which job plots will be updated even if not requested via HTTP. Non-positive values will make the plots not being updated and saved unless requested via HTTP (see \\-\\-plot-timeout for controlling maximum age of those). Plots are saved at exit under the same name as the log file, with the .log extension removed. (default: 120 seconds)

- **--plot-timeout** TIME

  Maximum age (in seconds) of plots served over HTTP; they will be updated if they are older. (default: 30 seconds)

- **--refresh** TIME

  Refresh rate of automatically reloaded web pages (summary, logs, ...).

- **--timing** COUNT

  Repeat each job COUNT times, and output a simple table with average/variance/minimum/maximum job duration; used for measuring how various parameters affect execution time. Jobs can override the global value with the !COUNT column.

- **--timing-output** FILE

  With \\-\\-timing, save measured durations to FILE, instead of writing to standard output.

- **--randomize**

  Randomize job order (within constraints given by assigned cores).

- **--disable-pynotify**

  Disable screen notifications

- **-L**, **--libs** IMPLIBRARIES

  import libraries at startup before importing yade libs. May be used when the ordering of imports matter (see e.g. https://bugs.launchpad.net/yade/+bug/1183402 */comments/3*). The option can be used multiple times, as in "yade **-Llib1** **-Llib2**"
