[SOLVED] band parallelisation in finite electric field?

Post by hongjw10 » Wed Apr 27, 2011 9:15 pm

Hi, all

I'm trying to do the finite electric field calculation (berryopt=4) for a supercell (30 atoms). The nkpt=3 and band=72 in this system. So I want to use band parallelisation in my calculation. But after I set up the flags (paral_kgb=1 npband =4 npkpt = 3 npfft =1 bandpp=2) to do the finite field calculation ( I got the WFK from non-scf calculation first), the calculation stops after reading the WFK file. I attached the the end of log file as following: (the input file is also attached ).

I also tried (paral_kgb=1 npband =4 ) or (paral_kgb=1 npfft =4 ), the same error occurs. This band parallelisation is also not working for non-scf calculation. But it works well for ground state calculation, for example, I use paral_kgb=1 npband =4 npkpt = 3 npfft =1 bandpp=2, the calculation work fine.

So, I want to know whether the band parallelization is not available for finite electric field calculation (I used Abinit v6.6.2), or did I missed some flags in the calculation?

Thank you in advance.

To my knowledge, band parallelization is not available with berryopt 4, only kpt.
