Thank you very much for your comment. As Nichols said, this is a "mission impossible" for my hardware. And my timestep is 5 a.u., instead of 5 fs, I think, which makes it a 20 years job :-( I will try smaller system.
Thank you very much!

This is somewhat a too hard statement -
this is RELATIVE to the amount of computer power you have or you would like to dedicate to the project -
On a single BG/L rack you can go to < 1 sec per step on this system -
:-)

Also, the amount you want to run is somewhat unrealistic for ab initio MD.
An it looks like your input file is using 5 fs time step... you can probably get away with that at your low temperatures
1 ps = 200 time steps
You want to run
100 ps = 20,000 steps
So you are talking about a simulation that would take 4.5 years using your estimate of 120 seconds per step.

Tangfei,
the scaling with respect of system size is between N2logN and N3 - depending on the fact FFT or orthogonalization is dominating the calculation - so from
32 to 512 atoms you can expect a factor between 256 to 4096 running on the same hdw and number of processors - you are using 4 times the number of nodes - so supposing an ideal
scaling you should have something between 64 to 1024 slower. Therefore something between 32 to 512 sec per step............. so your time is reasonable ( given the fact that in your system linear algebra just start to dominate).
If you want to save some time - and you really want to do only silicon ( MT) - you could reduce the cutoff to 20Ry - Silicon should be already converged at that cutoff ....

Subject [CPMD-list] slow MD!
Dear all:
I'm running a CP-MD on 512 Si atoms in a rectangular supercell at 150K (I just want to let the lattice vibrate around its equilirium position and I want to run it for several hundred picosecond, it that possible? If not, how long would be possible.). I first did a geometry optimization and then started the MD steps. However, the MD steps are very slow, which take SGI 16 CPUs (with 40Gb memory) 120-130sec/step. When I ran MD for 32 Si atoms using 4 CPUs, it only took 0.5sec/step. Is that normal? Will BOMD be quicker? Will changing another PP affect the speed? What parameters can be changed to increase the speed?
Any advice would be greatly appreciated!
I attach my input file for geometry optimization and CPMD below:
