Dear Dr. Axel Kohlmeyer,
Thanks for your valuable suggestion. The issue here is not to cheat physics rather finding out some way using the configuration file (if at all exists) other than using GPU or multiple CPU to make the calculations little faster.
And faster here do not mean accepting anything which provides wrong output or by any means compromising the true results .
Reducing time cannot be done with the cost of true results.
The question here is whether in a single quad core system is it possible to run two simulations simultaneously?
Anyways, thanks for your reply.

you cannot cheat physics. well, not unless you are a rare genius. what
use is to have results faster, if they are incorrect?
so the only way to get your work done correctly and faster is to get
hold of more CPUs. NAMD parallelizes very well and there are plenty of
parallel compute resources. it only takes some effort to get hold of
