<div>The time difference is : for simulation with every 100ps output, 160ns/day; for simulation with every 0.1ps output, It has been running for 4 days, only wrote to 2300ps . I am not sure the local hard disk since I run my simulation in some cluster. Thanks. </div>

<div class="Wj3C7c">Hello, all:<br> I compare the two simulations with different output frequency for .xtc file in same machine. One with low frequency runs much faster than the one with high frequency. Is that reasonable? I think the frequency shouldn't affect the simulation speed. Anyone has idea about this situation? Thanks. -Xianghong Qi <br>
