[Wien] Wien2k 13 installation without FFTW3

2013-06-28 Thread michel

Dear Wien2k users,

I installed wien2k 13 in my machine and I noted that now, when we  
configure the parallel instalation, the siteconfig script asks for  
what FFTW we have installed. I have just FFTW2, so this is the one I  
chose. The instalation was sucessfull, without errors. Then I tested  
the instalation and I got an error message at mixer, saying that it  
could not find the fftw3 libraries. I thought it was strange, since I  
wanted to install using FFTW2. I looked at the Makefile for Mixer and  
at the compiler options was -DFFTW3 and at the libraries -lfftw3. So I  
changed -DFFTW3 to -DFFTW2 and -lfftw3 to -lfftw and compiled again.  
This time the calculation was sucessfull. So I tried to minimize the  
internal forces at the structure and this time I got the same error  
message at the Pairhess program. Again I looked at the Makefile and it  
was using FFTW3 instead of FFTW2. I did the same modification and the  
program run sucessfully. Now, I have two questions:


1) Can I change the Makefile at these programs so that they use FFTW2  
or do they need FFTW3?


2) Are there any other programs in which I have to change the Makefile  
manually, so that they use FFTW2 instead of FFTW3?


Thank you very much for your attention.

Best regards,

Michel Lacerda

2013-06-28 Thread Laurence Marks
A quick answer about mixer  pairhess; neither use any version of fftw
so changing the Makefile is completely safe.

I have not analyzed the new siteconfig/Makefile structure in wien2k_13
in detail, the FFTW* options are new, maybe there are some minor
glitches in them (what you found looks like a bug) which Peter will
presumably cure.

Re: [Wien] Wien2k 13 installation without FFTW3

2013-06-28 Thread Masood Yousaf
Respected Community Members

I just want to give a suggestion. I see off and on emails regarding WIEN2k 
installation. May any one make a screen video of installating WIEN2k with 
proper pre-requisite and a test run with parallel Job submission. Screen video 
recordings can be used to illustrate many complex things beside installation. 
Personally I got a lot of benefit by turning on Screen recorder on my system 
whenever someone teach me something which requires a lot of steps with multiple 
selection of options.

Re: [Wien] survey results

2013-06-28 Thread Laurence Marks
As a follow up, can I request a little more information comparing the
New and Old setrmt algorithms perhaps in a FAQ. I just noticed a very
large difference between them for bulk LaAlO3, e.g.

Old:
atom  Z   RMT-max   RMT
 1   8.0  1.77   1.77
 2  13.0  1.77   1.77
 3  57.0  2.5  2.5

New
atom  Z   RMT-max   RMT
 1   8.0  1.95   1.95
 2  13.0  1.60   1.60
 3  57.0  2.5  2.5

I assume that the New algorithm is better and this is right, but  it
would be helpful to know why O is now being chosen so much larger than
Al, more like the relative atomic radii

 One week ago, a two-question survey was posted on this mailing list.
 Here comes the result and a discussion/interpretation of the data.

 The goal of the survey was to collect quantitative information on the
 following hypothesis:

 In the transition from code development to code usage, inevitable some 
 awareness and knowledge about fine (?) details gets lost. Developers tend to 
 think that users know
 more than they actually do. While users tend to think that there are less 
 hidden subtleties than there actually are. It might well be that grey 
 intermediate area of
 supposed/lacking knowledge is far larger than either of both parties thinks 
 it is.

 The discussion of one week ago about the relation between RKmax and Rmt 
 offered an opportunity to collect some data to examine this hypothesis. The 
 topic was one about
 which an experienced user could think: You can't use wien2k properly if you 
 don't know this. While a 'general user' could think: I can survive without 
 this.

 34 people filled out the survey. Less than the 100 I hoped for, but 
 nevertheless sufficient for meaningful conclusions. The results can be found 
 for a while at
 https://dl.dropboxusercontent.com/u/10829484/Results%20RKmax%20survey.pdf 
 (attachment too large for this list).

 1/3 of the respondents say they could have given the right answer on the 
 RKmax question themselves. 2/3 say this was new for them. As one can expect 
 that users who have no
 clue at all about the topic are less
 likely to take part in the survey, it seems fair to conclude that 75% or 
 more of the wien2k community was not aware about this RKmax issue. A
 number that might surprise some people.

 Whereas the first question of the survey roughly probes 'understanding', the 
 second question of the survey asked about 'experience' (measured as the 
 amount of years someone
 has been using wien2k). Slightly less than one half of the respondents were 
 relatively new users (3y), the other half were quite to very much 
 experienced (3y, 7y). It is
 interesting to correlate the answers on both questions in a 
 knowledge-vs-experience graph (3th page of
 https://dl.dropboxusercontent.com/u/10829484/Results%20RKmax%20survey.pdf ) :

 It is reassuring to observe in this correlation that roughly spoken 
 understanding seems to increase as a function of experience (or time). 
 Nevertheless, even in the
 category of the most experienced users (7y), there are still almost twice 
 as many who were not aware of the RKmax issue than those who were (26% vs. 
 15%).

 This is only a rough observation, that does not pretend to be a 
 statistically significant scientific study. It does point to a trend, 
 however.

 The bottom line: is there anything all of us, as a community, can do to 
 improve the knowledge transfer towards 'general users'? Feel free to discuss 
 this on this mailing
 list, and in particular, to post suggestions.

Re: [Wien] Wien2k 13 installation without FFTW3

2013-06-28 Thread Peter Blaha
This looks a bit strange to me, but of course maybe it happens due to 
some special way you run   siteconfig.


a) In my Makefiles, fftw appears ONLY in the programs which have a 
parallel option (lapw0,1,2,dstart,hf). All other codes do not have fftw 
in the Makefile.


b) Without checking: maybe it could happen because
i) you selected firstFFTW3
ii) then respecified the sequential   FOPT (here the FFTW2 got
inserted into the Makefiles)
iii) then you changed in the parallel options the FFTW2-FFTW3,
 but you did NOT respecify the sequential OPTIONS.

But then still, I do not understand why it happens just for mixer and 
pairhess


As was mentioned before, the non-parallel programs don't need FFTWs
(but they do not harm, as long as you put them in correctly).

Check $WIENROOT/OPTIONS. What is in the two FFTW... lines (and FFTW 
should not appear in any other lines.


You can run siteconfig again, specify compiler options and save 
then. This should rewrite the Makefiles correctly.

Re: [Wien] error in lapw2

Did you also do point 1+2 of the faq page ?

Did you check the   Another possibility   of that page.

Did you see any changes. Is the error again in the 8th iteration ?

grep :DIS case.scf

Very often with the new mixer versions, ghostbands appear due to 
user-errors or due to a special case where the energy parameters need 
hand-tuning.


Buth without details, nobody can help.

Re: [Wien] survey results

2013-06-28 Thread Peter Blaha

The answer is simple: it is a  bug.

As listed on the faq page  http://www.wien2k.at/reg_user/faq/rkmax.html
the necessary RKmax for Al and O are both 6.5.
Therefore the spheres should be equal.

These RKmax estimates come from total energy tests of an atom in a 
simple box.


For Al, however, the convergence depends a lot on the semicore-treatment 
and at first I had obtained a RKmax=4.5 for Al, but later on it was 
updated to 6.5.
Unfortunately, setrmt has the Al in both, the 4.5 and 6.5 section and 
thus uses 4.5, which will then make the Al sphere smaller than O.


# Li, Al, Si
sub rkm4_5 {
my ($a) = @_ ;
if ( $a == 3 || $a == 13 || $a == 14 )  {
return 1;

Removing a == 13 from the above, should fix the problem.

I'll update the sources.

 more than they actually do. While users tend to think that there are less 
 hidden subtleties than there actually are. It might well be that grey 
 intermediate area of
 supposed/lacking knowledge is far larger than either of both parties 
 thinks it is.

 The discussion of one week ago about the relation between RKmax and Rmt 
 offered an opportunity to collect some data to examine this hypothesis. 
 The topic was one about
 which an experienced user could think: You can't use wien2k properly if 
 you don't know this. While a 'general user' could think: I can survive 
 without this.

 34 people filled out the survey. Less than the 100 I hoped for, but 
 nevertheless sufficient for meaningful conclusions. The results can be 
 found for a while at
 https://dl.dropboxusercontent.com/u/10829484/Results%20RKmax%20survey.pdf 
 (attachment too large for this list).

 1/3 of the respondents say they could have given the right answer on the 
 RKmax question themselves. 2/3 say this was new for them. As one can 
 expect that users who have no
 clue at all about the topic are less
 likely to take part in the survey, it seems fair to conclude that 75% or 
 more of the wien2k community was not aware about this RKmax issue. A
 number that might surprise some people.

 Whereas the first question of the survey roughly probes 'understanding', 
 the second question of the survey asked about 'experience' (measured as 
 the amount of years someone
 has been using wien2k). Slightly less than one half of the respondents 
 were relatively new users (3y), the other half were quite to very much 
 experienced (3y, 7y). It is
 interesting to correlate the answers on both questions in a 
 knowledge-vs-experience graph (3th page of
 https://dl.dropboxusercontent.com/u/10829484/Results%20RKmax%20survey.pdf 
 ) :

 It is reassuring to observe in this correlation that roughly spoken 
 understanding seems to increase as a function of experience (or time). 
 Nevertheless, even in the
 category of the most experienced users (7y), there are still almost twice 
 as many who were not aware of the RKmax issue than those who were (26% vs. 
 15%).

 This is only a rough observation, that does not pretend to be a 
 statistically significant scientific study. It does point to a trend, 
 however.

 The bottom line: is there anything all of us, as a community, can do to 
 improve the knowledge transfer towards 'general users'? Feel free to 
 discuss this on this mailing
 list, and in particular,

I removed the Makefiles for Mixer and Pairhess, run siteconfig again  
and saved the options. It seemms to have worked, at least the  
Makefiles for mixer and pairhess are correct now. Thank you very much!


Michel Lacerda

Quoting Peter Blaha pbl...@theochem.tuwien.ac.at:

This looks a bit strange to me, but of course maybe it happens due  
to some special way you run   siteconfig.


a) In my Makefiles, fftw appears ONLY in the programs which have a  
parallel option (lapw0,1,2,dstart,hf). All other codes do not have  
fftw in the Makefile.


b) Without checking: maybe it could happen because
i) you selected firstFFTW3
ii) then respecified the sequential   FOPT (here the FFTW2 got
inserted into the Makefiles)
iii) then you changed in the parallel options the FFTW2-FFTW3,
 but you did NOT respecify the sequential OPTIONS.

But then still, I do not understand why it happens just for mixer  
and pairhess


As was mentioned before, the non-parallel programs don't need FFTWs
(but they do not harm, as long as you put them in correctly).

Check $WIENROOT/OPTIONS. What is in the two FFTW... lines (and FFTW  
should not appear in any other lines.


You can run siteconfig again, specify compiler options and save  
then. This should rewrite the Makefiles correctly.

Dear Wien2k users,

I installed wien2k 13 in my machine and I noted that now, when we
configure the parallel instalation, the siteconfig script asks for what
FFTW we have installed. I have just FFTW2, so this is the one I chose.
The instalation was sucessfull, without errors. Then I tested the
instalation and I got an error message at mixer, saying that it could
not find the fftw3 libraries. I thought it was strange, since I wanted
to install using FFTW2. I looked at the Makefile for Mixer and at the
compiler options was -DFFTW3 and at the libraries -lfftw3. So I changed
-DFFTW3 to -DFFTW2 and -lfftw3 to -lfftw and compiled again. This time
the calculation was sucessfull. So I tried to minimize the internal
forces at the structure and this time I got the same error message at
the Pairhess program. Again I looked at the Makefile and it was using
FFTW3 instead of FFTW2. I did the same modification and the program run
sucessfully. Now, I have two questions:

1) Can I change the Makefile at these programs so that they use FFTW2 or
do they need FFTW3?

2) Are there any other programs in which I have to change the Makefile
manually, so that they use FFTW2 instead of FFTW3?

Thank you very much for your attention.

Best regards,

Michel Lacerda

[Wien] band structure dependence on symmetry and complex calculation

2013-06-28 Thread venkatesh chandragiri
Dear wein2k users,

I have calculated the band structure of the Fe2VAl lattice (fm3m, 225) for
the two cases.

*case one* : using the space group (225) defined structure with three atoms.

*case two* : by seeing the structure of Fe2VAl in xcrysden, i have
generated the case.struct file with 16 atomic unit cell (8-Fe, 4-V, 4-Al)
with a 16 number of co-ordinates such that the structure looks same as in *case
one*. But, in this structure file, i have used space group as a primitive
(1).

Using the Powder cell software, i also checked the XRD of the structures
from the both cases and similar diffraction pattern were found. I run the
volume optimization and min positions before running the spin polarized SCF
calculation. However, In the First case (space group structure), we run the
calculation without complex (no inversion). But, in the second case
(primitive), we did the calculations with keeping complex ON.

Now, i done the spaghetti plots for these two structures. For the space
group case, we have observed indirect band picture between gamma and X
k-points (X point will always followed by gamma). This nature is already
reported in the literature also. But, for the second case with primitive
structure, i have found the direct band like picture in which both band are
touching at the gamma point.

In preparing the case.klist and case.klist_band, i have used similar
k-point co-ordinates for the both cases.

Why the bands above the Fermi level would not shift to x point in the
primitive case. Is there any effect of removing the symmetry on the band
structure even though we did calculations on the similar structure...?

or else in the first case, calculations did with complex OFF while in the
second case with complex ON. Is this difference will change the band
structure nature...?

I could not attach the obtained figures, because i sent same mail with
figures in few days before but it is not published in wien2k mailing list
due to limitations in the mail content size.

thanks in advance and waiting for your replies.

Re: [Wien] band structure dependence on symmetry and complex calculation

2013-06-28 Thread Rocquefelte
I have the feeling that your problem is related to the Bravais lattice 
which is F-centered and Primitive in the first and second cases.
It is not related to the way the calculation is done (complex or not). 
Indeed, when you are using the space group Foum-3m, WIEN2k is doing the 
calculation in the related primitive cell which is 4-times smaller than 
the F-centered one.
In constrast when you are doing the calculation with the initial 
structure but keeping the P1 symmetry, WIEN2k do the calculation for the 
full-cell. Thus in the reciprocal space the directions will be different 
and thus the path.


On the other hand, could you provide the 2 structures to check that you 
didn't forget atoms in the case of the P1 symmetry calculation.


Best Regards

Xavier

Re: [Wien] band structure dependence on symmetry and complex calculation

2013-06-28 Thread Peter Blaha

This is related to what is called backfolding.

Remeber basic solid state theory:

A direct lattice with lattice constant a, has a reciprocal lattice with  b=2pi/a

Now double the direct lattice (a'=2a), the reciprocal lattice b'=2pi/a'= pi/a

Now now pi/a referes to the X point in the original lattice, but this same 
pi/a
is a full reciprocal lattice vector for the supercell and thus appears at Gamma.

This is called backfolding of of the second half of the Gamma-Delta-X branch 
back to
Gamma-Delta(now X')-Gamma.

There fore the original Gamma-X gap is now a direct Gamma-Gamma gap.
