[gmx-users] Re: High frequency output slow down the simulation?

[Yang Ye]

Writing on local or remote certainly makes a difference. How about the speed with no output at all?

 Regards,
Yang Ye

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.

More details please.
Local hard disk?
How much the time difference?

Hello, all:
 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
