Re: ABINIT 7.2.1 + CUDA + MAGMA [SOLVED]

Hi,
I came across the same compilation problem as iberezk7. This is caused by some defects in Magma 1.3.0 .
You may refer to this post to find the solution: http://icl.cs.utk.edu/magma/forum/viewt ... ?f=2&t=789

Best regards,
Agnxy

Re: BSE code does not support metals

Dear All Abinit does not support metals, which my system is CuBO_2 (copper boron dioxides). How can I solve this broblem Thanks Abdulmutta Hi all, I recently came across the same problem when I studied optical properties of C3N4. It shows metallic behavior in DFT-LDA, but actually turns out to be s...

Re: bs_calctype and soenergy

Hi all,

It seems that I made some mistake in my previous calculation. When running BSE with bs_calctype=2, the QP energies are obtained from a __in.gw__ file and the k-points in BSE and GW calculation must be consistent, otherwise the QP energies can not be used correctly.

Re: bs_calctype and soenergy

Hi All, I also have the similar question as Saniz mentioned. I'm using abinit-6.10.3 and performing some tests on BSE. I note that if I set bs_calctype=2 to use the _GW file from one-shot GW calculation as the Input and set soenergy=0 eV, the output spectrum has a red shift compared with the case us...

Re: Unusual LDA eigenvalue when using parallel version of AB

Recently I solve this problem by eliminating the input variable "nbdblock". I'm not sure about the root cause. Just FYI.

Unusual LDA eigenvalue when using parallel version of ABINIT

Hi All, I'm still a rookie for ABINIT and I'm now working on band structure calculation of graphitic carbon nitride. When I moved on to the step of the LDA band structure, I tried to use the parallel version to accelerate my calculation. Unfortunately I got a strange result compared with the one wit...
