to help you we could use some information about the hardware you use.
Approximating you use linux, please supply the output of the following
1. cat /proc/cpuinfo
This should be enough for the beginning.
PS: If not using linux, please give otherwise information about the hardware

Betreff: namd-l: LES very slow
I'm trying to run LES on a system of ~30.000 atoms. I'm using 20 copies of
each of two dyes attached to DNA. The problem is when I extend the
simulation to more than one cpu the scaling does not increase accordingly.
An increase from one to 12 cpus only gives a decrease in simulation time
from ~9 days to ~4 days pr. ns. Does anybody know how to solve this?
Best regards, Siri
