btw.
Is this type of error in the second test you propose something to worry about:
No YAML Error found in [paral][t77_MPI4][np=4]
[paral][t80_MPI1][np=0]: Skipped.
nprocs: 4 != nprocs_to_test: 1
[paral][t80_MPI2][np=0]: Skipped.

Re: Recompiling Abinit with multicore support [SOLVED]
It finally seems to work! :-) great!! Thanks! Is it better to have 8 core support despite having only 4 CPUs? Is it for the hyperthreading? Is it difficult to add GPU support from here? Do you know how the GPU support should be added correctly? And how is GPU used when running the calculations? Is t...

After make try it : export OMP_NUM_THREADS=n n = number threads If it doesnt work , using make multi multi_nprocs =n for using “n” processors on a SMP machine where you have to replace “n” by its value) Good luck.

Re: Recompiling Abinit with multicore support [SOLVED]
So is there a way to compile abinit with mpi and multicore support on my system? other than the way you suggested since it does not work in my case.

Re: Recompiling Abinit with multicore support [SOLVED]
using make and make install I get errors now, but probably because it was already installed. Now the SCF runs but the out file is not completed afterwards.

Re: The use of magnetic moment, kpoints, ionmov, supercells, and DOS
Thanks for the answers! I still have some questions on some of the answers to clarify them. 1) the array [3, natom] for the spinat, does it represent 3 coordinates and number of atoms according to xred? In my case I have 30 atoms and have set the magnetic moment to 4 for the Mn positions along the z...

The use of magnetic moment, kpoints, ionmov, supercells, and DOS
Hi, I was trying to test a couple of different parameters related to the magnetic moment, kpoints and the ionmov, supercell but don't know if there's something wrong. The compound is an Mn-oxide with an antiferromagnetic structure and I expect the Mn moment to be ~4 µB/ion but when I run the calcula...

Re: Using spgroup correctly
Dear Eric So you mean that I have to list all atoms in the unit cell at all times? I thought the spgroup was able to use symmetry operators and construct the whole cell by providing the Wyckoff positions of the assymetric cell. Is spgroup only used to specifically designate a space group type to the...
