<P><B>Description:</B>
|
|
</P>
|
|
<P>Print out information about the current internal state of the running
|
|
LAMMPS process. This can be helpful when debugging or validating
|
|
complex input scripts. Several output categories are available and
|
|
one or more output category may be requested.
|
|
</P>
|
|
<P>The <I>out</I> flag controls where the output is sent. It can only be sent
|
|
to one target. By default this is the screen, if it is active. The
|
|
<I>log</I> argument selects the log file instead. With the <I>append</I> and
|
|
<I>overwrite</I> option, followed by a filename, the output is written
|
|
to that file, which is either appended to or overwritten, respectively.
|
|
</P>
|
|
<P>The <I>all</I> flag activates printing all categories listed below.
|
|
</P>
|
|
<P>The <I>system</I> category prints a general system overview listing. This
|
|
includes the unit style, atom style, number of atoms, bonds, angles,
|
|
dihedrals, and impropers and the number of the respective types, box
|
|
dimensions and properties, force computing styles and more.
|
|
</P>
|
|
<P>The <I>computes</I> category prints a list of all currently defined
|
|
computes, their IDs and styles and groups they operate on.
|
|
</P>
|
|
<P>The <I>dumps</I> category prints a list of all currently active dumps,
|
|
their IDs, styles, filenames, groups, and dump frequencies.
|
|
</P>
|
|
<P>The <I>fixes</I> category prints a list of all currently defined fixes,
|
|
their IDs and styles and groups they operate on.
|
|
</P>
|
|
<P>The <I>groups</I> category prints a list of all currently defined groups.
|
|
</P>
|
|
<P>The <I>regions</I> category prints a list of all currently defined regions,
|
|
their IDs and styles and whether "inside" or "outside" atoms are
|
|
selected.
|
|
</P>
|
|
<P>The <I>variables</I> category prints a list of all currently defined
|
|
variables, their names, styles, definition and last computed value, if
|
|
available.
|
|
</P>
|
|
<P>The <I>time</I> category prints the accumulated CPU and wall time for the
|
|
process that writes output (usually MPI rank 0).
|
|
</P>
|
|
<P>The <I>configuration</I> command prints some information about the LAMMPS
|
|
version and architection and OS it is run on. Where supported, also
|
|
information about the memory consumption provided by the OS is
|
|
reported.
