[Pw_forum] scf calculation crashed for "diagonalization (ZHEGV*) failed".

2012-07-18 Thread GAO Zhe
By the way, do you want to calculate the FCC structure (diamond structure)? If 
so, your model/structure is definitely wrong~
For FCC, the primitive cell contains two atoms, one at (0,0,0), another at 
(1/4,1/4,1/4), and the cell vectors should be as you used.

If there is no model/structure problem, then you can try to set 
diagonalization='cg' in &electrons namelist, although this method will decrease 
the calculation speed due to the poor parallel performance.

you should first of all check your atomic positions: they look
strange to me. This message is very often a consequence
of strange input atomic positions, such as almost overlapping
atoms

[Pw_forum] scf calculation crashed for "diagonalization (ZHEGV*) failed".

2009-09-18 Thread Gabriele Sclauzero
Dear Haowei Peng,
 in my experience this error may happen with GGA functionals when you push 
the scf 
threshold very low (let's say conv_thr below 10^(-10) ). Since you're hiding 
some relevant 
information of your input file (such as PP files, atomic coordinates and 
k-points) I 
cannot be sure if this is causing the problem.
In your case conv_thr = 1.0d-8, which is not that low, so there may be other 
problems, 
such as a wrong set of coordinates on input, a bad pseudopotential, ...
Maybe, you can try to increase the cutoffs.

Thanks all..
and sorry for my sending the mail repeatedly (I kept receiving mails which
told me that my mail was not delivered successfully...)

finally I set the calculation restart mode to "restart"...and it give a
result which seems right, at least the total energy
but I have to check the other information.

Dear Haowei Peng,
your input looks ok, apart that you may have missed to set lda_plus_U to
true (or you just wanted to try the calculation without the U)
>lda_plus_u=.false. Hubbard_U(1)=1.d-8

I'm having this error a lot on a specific hardware with a specific version
of ifort+acml libraries. On the same hardware, with mkl I can't even
finish the first iteration because of those diagonalization errors.

I know it's not a great advice, but I would try a different version of the
compiler, just to be sure.
