NPAR optimization

#1 Post by jsfilhol » Tue Feb 08, 2011 2:59 pm

With vasp5.2.11 we are obliged to run with NPAR = nb of core for parallel runs to get response theory working but also for vibrations even with IBRION=5 that is surprising for a finite displacement algorithm. Using NPAR=nb of core /8 is nearly twice faster for geometry optimization but crashes for the other calculations (vibration polarization...). Is there a way to solve this problem at least for the ibrion=5 calculations .... to optimize our parallelization ?

Thanks for the help
