"Exactly", hard to tell, but I would have a look at the estimated memory
for your run: do you have that much memory available?

Dear Theo,
unrelated, but it's not a super good idea to describe a paramagnetic
state with a non magnetic calculation - many paramagnetic systems have
still strong local moments, that are disordered. At high pressure the
local moments can disappear (e.g. iron at the ~330GPa of the
liquid-s
Dear Iurii,
I'll have a look into the source code to see if I can spot anything there.
I suspect the only other cause of this could be that the calculation were run
on two different machines (ARCHER2 vs CSD3) although I can't see obviously why
it would cause this specific problem.
In any case,
Dear Iurii,
Yes, to be more precise I mean that when I am looking at these systems, I am
modelling them as being nonmagnetic and so I was wondering whether it was the
spin degeneracy that was causing this difference.
I am typically looking at pressure-induced structural transitions in systems
Dear Theo,
Thanks for clarifications!

Dear Theo,
How do you model the paramagnetic state? Please note that "paramagnetic" and
"nonmagnetic" state is not the same thing.
For nonmagnetic calculations there is a factor of 2 due to spin degeneracy when
computing sums over electronic states (i.e. in charge density, occupation

Dear Quantum Espresso Users,
I have been using the hp.x code to calculate the Hubbard-U corrections for
correlated metallic systems in both their spin-polarised and paramagnetic
states.
In several materials I have noticed that the Hubbard-U value determined for a
material in its paramagnetic g
