<div>Hi,</div><div><br></div>I think 80000 atoms system is too big for AIMD simulation.... Maybe classical MD (gromacs or lammps) can handle this large system.<div><br></div><div>Regards,</div><div>Hongyang</div><br><div class="gmail_quote"><div dir="auto" class="gmail_attr">在2021年6月11日星期五 UTC+10 上午4:03:41&...@gmail.com> 写道:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">I am sorry, I am a new to use google group, maybe I have send you many email by private, please ignore them.<br><br><div>So the RAM is 16GB*24~~~~~382GB</div><div>And I want to do AIMD simulation(deposit atoms on the surface, the surface is 20nm* 20nm)</div><div><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">在2021年6月10日星期四 UTC+8 下午10:18:55<<a href data-email-masked rel="nofollow">sc...@gmail.com</a>> 写道:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">How much RAM you have and what kind of simulation you are doing? <br><br><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Thursday, June 10, 2021 at 5:50:42 PM UTC+5:30 <a rel="nofollow">ya...@gmail.com</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">And if I run cp2k-8.2(GPU version), it report error "
