Re: hwo to continue a job in one dataset ?

Hello, You can restart from dataset 4 by setting ndtset 2 jdtset 4 5 (meaning, there are two datasets and their numbers are 4 and 5) but you cannot restart dataset 4 where it stopped. David David, Thanks for your advice. I know the way you said. I want to know how to restart dataset4 from where it ...

hwo to continue a job in one dataset ?

hello, I have run a job about computation of non-linear optical susceptibilities for two months, unfortunately, the job was killed by my careless manager. The job was stopped in DATASET4, and most job of this DATASET has been completed. If I want to continue the job from the end of DATASET4 , how to...

Re: Configure problem about Plug-ins for abinit6.6.1

Hi Mazuju, No need to throw the baby out with the bath water. Download http://archives.abinit.org/plugins/atompaw-3.0.1.tar.gz "by hand" - for example with wget - and copy it into ~/.abinit/tarballs/ If all the rest goes well, you'll finish with a cute Atompaw generator. Or go back to htt...

Re: Configure problem about Plug-ins for abinit6.6.1

The easiest for now is to disable AtomPAW: ../configure --with-dft-flavor="bigdft+libxc+wannier90" Please also note that GCC 4.1 is a lttile bit oldish and might not be able to compile Abinit. I suggest you to install a newer version. 4.5 is performing very well. Hi, pouillon Yes ,you are...

[SOLVED] Configure problem about Plug-ins for abinit6.6.1

hi, I have some trouble compiling ABINIT 6.6.1 in X86-64 . Compiler: gnu 4.1 ; Mpich version: openmpi 1.4 ; System: redhat Before configuring, I download all the Plug-ins needed for ABINIT6.6, and put them in the directory of "~/.abinit/tarballs/". These Plug-ins are atompaw-3.0.tar.gz, bi...

Re: problem ,gw1 tutorial... emergency

Hi,
It means to copy tgw1_2o_DS2_KSS to tgw1_3o_DS1_KSS and tgw1_2o_DS3_SCR to tgw1_3o_DS1_SCR when you come to section 3. Because in tgw1_3.in file, you can find :
getkss 1
getscr 1

How to get zero frequency second-order optical coefficient

Dear colleagues Is there anyone who have used Abinit to compute nonlinear optical properties, especially second harmonic generation? I have two questions. 1, In the Optic output files, I can only find the smallest frequency nonlinear optical coefficients but not the zero frequency. How to get zero f...

Re: How to deal with fractional occupation ?

The simple but very approximate way is to use the Virtual Crystal Approximation: see input variable mixalch and related variables. I think this approach is only allowed in abinit with norm-conserving pseudopotentials, not with PAW. The more "realistic" approach but more time-consuming is ...

Re: HELP: how to reduce the memory needs

Hi, Are you sure that you are really running out of RAM (memory) ? Your input file seems to run fine on my machine (with 2GB of RAM) until it feels my partition (after the beginning of dataset 4). The wave function files use 35 GB each... Maybe, during the run, you could remove wave function file t...
