Ciao Giacomo,

Sorry, I've never seen that.
Obviously, something is going wrong with memory management, and
it is probably independent of the 2x1x1 k-point grid.
Some few questions I can think of:
Does the molecule in its own optimized structure run ok ?.
Do you start from a fresh density matrix ?.
Have you played with the Diag.Memory parameter (check manual) ?.

On a another hand, from the source I can see that array ftmp2 is
being used in a MPI context. Thus I doubt you're really running
a serial code. Namely, a single processor, MPI-unabled code
may not be the same as a true serial one.

Hi Roberto,
differently from what I was thinking the serial version gives me this error message

siesta:    3    -2779.6431    -2749.0589    -2749.2928  1.0045 -0.6149
alloc_err: allocate status error          41
alloc_err: array ftmp2 requested by redistribXY

alloc_err: dim, lbound, ubound:  4       1     486
alloc_err: allocate error

This both in the case of the ghost atoms and the single point calculation of the molecule in the optimized geometry of the molecule+surface system.


Could you help me in figuring out the reason for this?

Once more I repeat: molecule, 2x1x1 k-point sampling, serial run.

Thanks a lot!

With best regards,
Giacomo
