I was so surprised that MD could collect many picoseconds in a day (some finished in an hour on IBM RS6000) while another mate stopped his MC in a week. Unfortunately, more CPU time doesn't mean more results and the dynamic properties owe its availability to MD. Which one, MD or MC, you will select if CPU time-constraint is imposed ? Both methods explore the phase space but MD seems to go ahead much faster. If the efficiency is one thing to think about MD is preferred since it never rejects the configuration. What is the advantage of MC and this should explain its survival through the year 2000. take care, Teerakiat --------------------------------------------------------------------------- Teerakiat Kerdcharoen (NOY) Institute of General and Inorganic and Theoretical Chemistry Innrain 52a, A-6020 Innsbruck AUSTRIA e-mail: noy -8 at 8- tci2.uibk.ac.at, noy -8 at 8- tci5.uibk.ac.at : noy -x- at -x- atc.atccu.chula.ac.th, noy -x- at -x- atc2.atccu.chula.ac.th ( Bangkok ) Research : Molecular Dynamics simulations : Computer Aided Molecular/Material Designs --------------------------------------------------------------------------- *** I still remember that night in Bangkok.
