Yade - manual page for Yade version: 1.20.0, features: Odeint VTK OpenMP GTS GUI-Qt5 CGAL


usage: yade-batch [options] [ TABLE [SIMULATION.py] | SIMULATION.py[/nCores] [...] ]

yade-batch runs yade simulation multiple times with different parameters. See
https://yade-dem.org/sphinx/user.html#batch-queuing-and-execution-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.

optional arguments:
-h, --help
show this help message and exit

-j NUM, --jobs NUM
Maximum number of simultaneous threads to run (default: number of cores, further
limited by OMP_NUM_THREADS if set by the environment: 4)

-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 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: [email protected])

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

--nice NICE
Nice value of spawned jobs (default: 10)

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/yadeKKgSmd/yade-1.20.0/debian/tmp/usr/bin/yade). Jobs can override with
!EXEC column.

--gnuplot FILE
Gnuplot file where gnuplot from all jobs should be put together

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

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

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