Wiki logs

1 Add Wiki theme moin-mandarin. Look at the link https://bitbucket.org/thesheep/moin-mandarin

2 Try to edit a bdftheme from modernized theme.

  1. Make a copy of the 'modern' theme in the static files directory and call it 'bdftheme'
  2. Copy the script of this theme MoinMoin/theme/modern.py' to data/plugins/theme/bdftheme.py
  3. Edit the file 'bdftheme.py' and change at least the variable name = "modernized" to {name ="bdftheme"}

Latex Support https://moinmo.in/ParserMarket/latex

Do not forget install latex, dvipng. All of these packages can be installed via apt-get.

Filename for all kind of local orbitals in BDF: 

 1. localorb   - local orbital generated by BDF module localmo. Boys and trust region methods are used in orbital localization. 
 2. blmo  - Boys.
 3. tlmo  - Trust region.
 4. flmoorb - fragment local orbital generated by bottom-up method.
 5. pflmo  - norm-orthogonal pFLMO.

BDF git version control user's guide

Start from a clean BDF copy bdfpkg 

Create directory
  cd bdfpkg
Initial a git bare repository. Notice we also use flag --shared. 
  git init --bare --shared
  git add
  git config --global user.name "your name"
  git config --global user.email "youremail@domain"
  git commit -m "Creat BDF package store"

get a bdf work copy

Obtain a bdf work copy
  git clone youname@10.105.153.100:/export/gitroot/bdf-pkg
You need set some general information such as user name and user email.
  git config --global user.name "Your name"
  git config --global user.email "youremail@domain"
Create your own branch

Use BDF with job management system

qsub

You should prepare a qsub script.

bsub

You should prepare a bsub script "my job".

BDF程序组织原则

BDF按照计算功能，编译成单独的模块。每个模块相当于Unix命令这样的工具，通过Python调用不同的实现复杂的计算功能。模块之间数据交换通过文件进行。

BDF计算时间测试数据

bdfbenchmark 

页面http://182.92.69.169:7226/bdfbenchmark提供了BDF的测试数据。这些数据不是为了与其他程序比较，只是BDF开发者用以评价BDF优化的如何，也给大家提供了一个对CPU和编译器效能的直观认识。具体时间与操作系统、编译器版本、CPU与内存配置，测试时系统的工作负载都有关。

Known bugs

Intel compiler 2018 is buggy. Keep away from it!

MPEC+COSX Keyword

Coulpot=0 or no Coulpot, ERI 
Coulpot=7003, Original MPEC
Coulpot=1004 or Coulpolt=-1, used as the default for Coulpot, aMPEC4, first SCF step use ERI
Coulpot=2004, aMPEC4, first SCF step do not use ERI

A lot of redundent codes will be removed after this commit.

BDF Compiling problems

1 ifort2019+gcc-9.4.2. Linking lsscf error. missing missing GOMP_loop_nonmonotonic_dynamic_next. May disable HILQC calculate Fock since it is not used at present. All gcc compilers >= 9.0 have such a problem. 

2 GNU compiler v5-v9, gfortran+gcc/g++, link with MKL, work fine.

3 ifort2021+gcc/g++(GNU 5-9), link with MKL, work fine.

4 ifort+icc/icpc, v2021, should use flag "-I/usr/inlcude/c++/11.x", head file of c++/12.1.0 has compiling problem.

Cmake Rpath handing

netlib lapack extension for C

It is tricky to compiler lapacke in the lapack package from netlib. See LAPACKE/README. For BDF, you should set -DHAVE_LAPACK_CONFIG_H -DLAPACK_ILP64 to use 64 integer interface. Also, the complex is used in BDF. I guess we should set -DHAVE_LAPACK_CONFIG_H -DLAPACK_COMPLEX_CPP because the double complex is used by Zhangning.
