The ABINIT Users Mailing List ( CLOSED )

[Marc Torrent <marc.torrent@cea.fr>]

Dear Masayoshi,

First of all, a remark concerning the memory need for useylm=1:
the additional amount of memory is justified by the fact that non-local 
form factors (ffnl Abinit variable) are now discritized by (l,m,n) 
quantum number instead of (l,n).
And you also add the memory needed by the spherical harmonics...

Now, concerning your problem of cpu time:
I'm currently looking at the 5.2.4-5.3.0 differences but it will need 
more time... it will be the subject of of a later mail.

Between 5.2.3 and 5.2.4:
You found that cpu time increases (1.618 h -> 3.489 h)... it's 
surprising !... because these two versions of Abinit do not have any 
differences for ground states calculations...
Only a few comments, new input keywords and tests have been added.
Just verify that your input file does not contain userid keyword 
(because Pierre-Matthieu changed some lines for that in 5.2.4).
The "major evolution" between 5.2.3 and 5.2.4 is the build system !...
Do you think it would be possible for you to compile Abinit 5.2.4 with 
5.2.3 build system ? (just try to copy /src directory from 5.2.4 to 
5.2.3 ???).
Another question: are you sure that you ran Abinit with the same 
environnement, in particular the computer load...
Can you reproduce several times the difference between 5.2.3 and 5.2.4 ?

That's all for today,
sorry,

Marc
