Fw: [CPMD-list] slow MD!

Much more than you could think of    :-)   ; 
and mine , of course, was a general statements - on modern  scalable hdws,
you can go very easily in the range of 100-500 ps per week with ab-initio 
MD -

Re: Fw: [CPMD-list] slow MD!






Unfortunately, not many of us have access to a BG/L :^(

However, I noticed in the 3.11 version of CPMD that it has also been 
ported over to the cray xt3. Do any benchmark exist?

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 ....

[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:
