user-intel optimization

Hi-
I have a question about the documentation on the USER-INTEL package. It suggests that you use ‘neigh_modify binsize 3’ Since this is setting the bin size in distance units, I don’t understand how this setting is optimal regardless of the units being used, and the system being studied. Any help is appreciated.
Thanks, Steve

Hi-
I have a question about the documentation
<http://lammps.sandia.gov/doc/accelerate_intel.html> on the USER-INTEL
package. It suggests that you use 'neigh_modify binsize 3' Since this is
setting the bin size in distance units, I don't understand how this setting
is optimal regardless of the units being used, and the system being
studied. Any help is appreciated.

​please note that this suggestion is always given in reference to using
PPPM. this in turn can only be used with certain pair styles for which
either real or metal units are common and both of those use angstroms as
distance unit.

Really that should read set the neighbor binsize to the neighbor cutoff,

not half the neighbor cutoff, which is the default. I’ll clarify that on the

doc page.

Thanks,

Steve

I see, thanks. That makes more sense.
