How to increase the CPU & RAM usage

Post by YJkim »

Hello, I need the solution to solve the CPU & RAM usage problem.
When I simulate Mn-Mn Dimer using pepper (with hybrid method), the CPU or RAM shares are below then half of the hardware.
Especially for the RAM, MATLAB(easyspin) program usually use only less then 5 GB. (even though the physical RAM is 16 GB.)
Is there any solution for unlock the limitation of RAM(or CPU)?
I guess it would be help to decrease the simulate time for dimer.
(I put the m-file code for my simulation below.)

Code: Select all

Sys.Nucs = 'Mn, Mn';
Sys.S = [5/2, 5/2];
Sys.g = [2.0017, 2.0017];
Sys.A = mt2mhz([93, 0; 0, 93]*0.1); 
Sys.D = [542 145;2497 284];
Sys.J = 6.08;
Sys.lwpp = [1 2];
 
Exp.mwFreq = 9.646; 
Exp.Range = [170 400];
Opt.Method = 'hybrid';
[SimX, SimY]=pepper(Sys,Exp,Opt); 
Thank you in advance for your effort and time.

This simulation is most likely not limited by RAM. The matrices associated with this problem are not excessively large - the state space dimension is 1296.
