See a recent version of the new user's guide, for an introduction to the abinit package. See a recent version of the abinis help file for learning how to use the code. Both of them can be found in the Infos subdirectory.
Any comment or suggestion to improve the procedure will be welcome ! Simply contact the ABINIT group.

We will distinguish three cases :
In the three cases, the installation files are available on the web site.
You must download different files for the different cases(x.x.x is the version).
Case 1 (under UNIX/Linux or MacOS X, and you want to compile) :
download the file src_tests_x.x.x.tar.gz
or
download the four files src_testsX_x.x.x.tar.gz where X is A, B, C or D
The src_tests_x.x.x.tar.gz gzipped tar file contains all the sources of the ABINIT code (including the files needed for generating the FFTs, NumRecip and Lapack libraries), the complete Infos directory, the complete set of Tests, all the scripts and makefiles, the pseudopotentials needed for tests.
It does NOT contain the object files and the binary executable files.
You might as well download separately four different tar.gz files named src_testsA_x.x.x.tar.gz, src_testsB_x.x.x.tar.gz src_testsC_x.x.x.tar.gz, and src_testsD_x.x.x.tar.gz . This opportunity is provided in case you have a slow connection to the ABINIT Web site, and think your ftp connection might be not stable enough to download the entire src_tests_x.x.x.tar.gz file : the four different files are each about one quarter of the single file, and altogether they contain also the full ABINIT package.
Case 2 (under UNIX/Linux or Mac OS X, and you do not want to compile) :
download platform_seq_x.x.x.tar.gz, for the sequential version only,
or
download platform_par_x.x.x.tar.gz, for the parallel version only (if it exists for the platform),
or
download platform_x.x.x.tar.gz, for sequential and parallel versions (if both exist for the platform).
Such gzipped tar files contains the binary executable files (sequential, or parallel, or both), the complete Infos directory, and the different files needed to execute either the 5 internal tests (sequential version), or tests from the Test_paral directory (parallel version), or both. In what follows, we will focus on the sequential executable (called abinis). One should begin to use the parallel executable (called abinip) only when sufficient experience has been gained with abinis.
The gzipped tar file does NOT contain the source files, neither the Test_fast, Test_v1, Test_v2, Test_v3 and Test_cpu directories, nor the corresponding pseudopotentials. The possible platforms are :For the Intel/Linux machines, the binaries contain all the library routines statically linked. They should be very portable (and they have been ported to more than 5 different machines in different countries, or of different construction ). However, they have been compiled by a compiler that generates code that needs an IP number to work. So, they will not run if your machine has not been IP'ed. For the other platforms, the executable does not contain all the library routines (they are linked dynamically), so they might not be as portable. The portability of the executable has been checked only for IBM PW2 and SGI Origin 2000 platforms.
- pclinux_pgi (PC under Linux, using the Portland Group Inc. compiler),
- pclinux_ifc (PC under Linux, using the Intel compiler - a bit faster),
- ibm_pw2 (IBM with Power 2 processors),
- ibm_44p (IBM model 44P with Power III+ processors),
- compaq_ev56 (DEC/Compaq machines with EV56 alpha processors),
- compaq_ev67 (DEC/Compaq machines with EV67 alpha processors),
- hp_pa7200 (HP PA RISC processors, model 7200),
- hp_pa8000 (HP PA RISC processors, model 8000),
- hp_pa8500 (HP PA RISC processors, model 8500),
- sgi_r10000,
- cray_t3e,
- sun_ultrasparc,
- fujitsu_vpp,
- nec
Case 3 (you want to run ABINIT under DOS/Windows) :
download intel_DOSWin_seq_x.x.x.exe, for the sequential version.
This is a self-extracting zip file that contains the binary executable files, the complete Infos directory, and the different files needed to execute the 5 internal tests. It does NOT contain the source files, nor the Test_fast, Test_v1, Test_v2, Test_v3 and Test_cpu directories, and the corresponding pseudopotentials.
Note : in order to compile ABINIT under DOS/Windows, you need the PGI workstation environment. The procedure to be followed differs from what will be explained below, and will not be described. Contact the ABINIT group if needed.
So, execute the following actions :
1) Transfer the above-mentioned file(s) to your machine, in a directory referred to here as ~local_ABINITvx.x.x . You should have about 100 MB of disk space to install the code, maybe more, depending on the version, and the number of tests that you will do.2a) Under UNIX/Linux, gunzip (on some machine you need gzip -d) and untar the file 'src_tests_x.x.x.tar.gz' or 'platform_x.x.x.tar.gz' (or the sequential or parallel reduction of the latter file) :
gunzip src_tests_x.x.x.tar.gz | tar -xvf -or
gunzip platform_x.x.x.tar.gz | tar -xvf -
2b) Under Windows, double-click the icon of the file intel_DOSWin_seq_x.x.x.exe to retrieve the files and directories. You can also run it as a command in a DOS window or use your favorite unzipping utility.
If correctly done, a whole set of subdirectories should have been created. One of them is called 'Infos'. It contains many important informations. In particular, you will find the description of the different subdirectories in the ~local_ABINITvx.x.x/Infos/dirs_and_files file. This file also describes the content of the Infos directory, that is, all the information files.
*** It is strongly adviced to the installer to read (and print) NOW the ~local_ABINITvx.x.x/Infos/dirs_and_files file. ***
If you were in case 2, then you already have the binary executables abinis, newsp, mrgddb and ifc, so that you might skip the present section and go to the internal testing. However, just for fun, if you are in UNIX or Linux, you can issue the make command, in the ~local_ABINITvx.x.x directory :
make
This will print the list of the basic keywords for the make utility. This list of basickeywords is completed by keywords specific to developers, obtained by typing
make dev
We now suppose that you have a F90 compiler and you want to compile the source files (case 1). You must provide to the 'make' utility some information: the location of F90 and C compilers on your machine, the cpp utility, the blas library, the location of PERL ... For this, you must create in the ~local_ABINITvx.x.x directory a file (or a symbolic link) named 'makefile_macros', that you will have to design starting from already existing example files. Examples of such files are contained in the subdirectories of the ~local_ABINITvx.x.x/Machine_dept_files directory. Actually, if one of the existing 'makefile_macros' file is suitable for you, you will have simply to issue an instruction like the following :
ln -s Machine_dept_files/DEC/makefile_macros.newton makefile_macros
(here, a symbolic link is created, so that 'makefile_macros' refers to Machine_dept_files/DEC/makefile_macros.newton , a file suitable for the DEC machine named 'newton' at the PCPM). In order to generate a new 'makefile_macros' file, a help file called 'help.makefile_macros' can be found in the ~local_ABINITvx.x.x/Infos directory. You can ask some help to the ABINIT group. When you have succeeded to create one such file, please send it to us, so that it can be maintained in the next versions of the code.
When the 'makefile_macros' file is ready, you will have to issue the 'make' command, followed by some keyword.
To get the sequential version of all the executables, you must type :
make allseqor
make allseq >& log.file
(allseq is an abbreviation for all sequential executables; log.file can be any filename, and is useful when the messages from make are too long)
Issuing this 'make allseq' command will trigger a whole set of
actions (not easy to follow, as you will see).
The make utility will use the file 'Makefile', that calls a script
called 'makemake', to produce another makefile, called
'tmp_makefile', that calls the 'makearch' script from different
subdirectories, that create themselves 'tmp_makefile' files, that
compile the fortran source (and eventually one C file), create
libraries and link the different objects.
Moreover, usually, this works without problem !
Let's us suppose that you do not issue the powerful 'make allseq' command, but that you want to create one-by-one the libraries and executables.
Then, for the sequential version, you must create :
Alternatively, the two libraries can be created at once by issuing 'make libs'.
Then, you can issue 'make abinis' to make the sequential version of abinit, and 'make newsp' to make newsp, the wavefunction translator. The latter is needed for different tests of abinis (see below). You can also issue 'make mrgddb' to make the code that merge the derivative databases, 'make ifc' to make the code that analyze interatomic force constant, 'make aim' for the Bader analysis utility.
In order to get a transferable executable on Intel/Linux machines, it might be needed to generate a static BLAS library. For this purpose, issue 'make blas'. Be consistent with this choice, at the level of the 'makefile_macros' file. This possibility is also used for the Fujitsu machines.
Informations needed to generate the parallel version of ABINIT can be found in the ~local_ABINITvx.x.x/Infos/paral_use file.
Suppose that something is going wrong in one of the above-mentioned steps, then, you can issue one of the 'clean_xxx' keywords (those mentioned by typing 'make') to clean the directory where something wrong happened.
With a bit of luck, you will succeed to generate the executables. You are ready to perform the tests.
In some cases, one wish to keep the binaries for different platforms in the same ~local_ABINITvx.x.x directory. It is possible to make the compilation execute in such a way that the result is stored in a machine-dependent subdirectory. Prior to the compilation on one platform, issue :
make bindir
Thanks to this command, a 'tmp_bindir' file will be created, containing the definition of a variable $(BINDIR). Usually, this variable will be BinAbinit/machine_architecture , where machine_architecture is the result of the execution of the `arch` command on the platform. This definition will be included in the make mechanism, and all the binaries will be put in $(BINDIR). For the compilation on another platform, the 'make bindir' command must be performed again, before compilation, and the binaries generated by that other compilation will be put in the corresponding directory. It is also possible to change the tmp_bindir file, to define another location, not obtained by the `arch` command. Note that, if any, the cleaning will be directed to the $(BINDIR) directory, which is the expected behaviour. However, presently, the tests (internal as well as v1, and others) CANNOT use the executables in the machine-dependent location : if the tests are to be done, one must first copy the proper executable in the ~local_ABINITvx.x.x directory.
The abinis code has five small internal tests, that can be issued automatically, and that check themselves whether the results that have been obtained are right or wrong. At most 3 MB of memory is required, and 1 MB of disk space. PERL must be installed on your machine for these tests to work. You can get PERL from http://www.perl.org . In the DOS/Windows case, perl.exe MUST be accessible through the DOS PATH
You can begin with the test number 1. Simply issue the command :
make test1
It will run during a dozen of seconds. It will first print
cd Test_in; Run 1
Built-in test 1 will be run through dotest script
dotest: Starting built-in test 1
../abinis < test1.files > test1.log
then, you will eventually (if you are on a slow machine) see different instances of the status file, like the following :
Status file, with repetition rate 49 , status number 99Level abinit : call gstate
Level gstate : call brdmin
Level brdmin : call scfcv_ini
Level scfcv : call vtorho
istep = 2
Level vtorho : compute rhog
then, the important information is as follows :
Status file, reporting on test 1OK for total energy
OK for nuclei positions
OK for forces
OK for stresses
This means that the internal test 1 ran successfully. If you do not get this message, then the executables were not properly generated, or there is a problem with the make and scripts that drive the internal test. In this case, after having tried to solve the problem by yourself, you should contact somebody in the ABINIT group.
Note : the script detects the end of the run by using the 'ps'
command following by a 'grep' command.
This can lead to strange effects if a file whose name contain
'abinis' is currently visualized, or if another job is running under
a name that contains 'abinis'.
So, close your files before running the tests, and also check that
there are no running jobs whose name contains 'abinis'.
Supposing test1 was OK, then you have to issue the command 'make tests'.
The test 1 will be done once more, followed by the 4 other internal tests. Again, we hope that you will get the positive diagnostics for the other tests. Altogether, these tests are about 50 sec on a Intel/PIII 450 MHz machine where no other job is running.
For further information on these internal tests, see the file ~local_ABINITvx.x.x/Test_in/README .
You might now read the new user's guide, in order to learn how to use the code. This is useful if you consider that the installation has been successful, or if you want to continue the tests.
(Case 1 only, since in case 2, only the minimal testing tools have been transferred)
Although it is possible to make the other tests without knowing really how to use the code (since all steps involved - the run and subsequent analysis - are done automatically), it is the right time to read the new user's guide.
After this reading, you should look at the subdirectory Test_fast, and, later, Test_v1 and Test_cpu, where tests of the sequential version of ABINIT (abinis) can be done automatically. For tests of the parallel version (abinip) see the directory Test_paral, as well as the ~local_ABINITvx.x.x/Infos/paral_use file. For tests of the response function features of abinis, and for tests of mrgddb and ifc, see the subdirectory Test_v2. Test_v3 presents further tests of recently implemented features of ABINIT.
In order to execute these tests, you will need a larger disk space than for the simple installation of the code (the total additional disk space required is on the order of 100 MB). After having checked the results of the tests, the user can easily retain the output files in a compressed form, and get rid off the wavefunction files by issuing
make decrease_size_tests
in the ~local_ABINITvx.x.x directory. Separate commands are available for each of the Test directories.
You might as well remove all working directories by issuing
make clean_tests
in the ~local_ABINITvx.x.x directory. Separate commands are available for each of the Test directories. This command remove all the subdirectories that begin with '_', which is the case of the working subdirectories. If you want to keep some of them, remove their initial '_', then issue make clean_tests. You can still decrease the size of such renamed directories by the make decrease_size_tests command.
1) Test_fast (for the sequential version only)
This subdirectory contains a basic set of tests of the code, aimed
at testing whether the code is coherent in time (successive
versions), and exercising many parts of the code. However, they do
not examine its accuracy on physical problems, mainly because the
number of plane waves used is too small, and some tests are not run
to self-consistent convergence. 32 MB of memory should be enough for these
tests (with no other application running, however).
Read the ~local_ABINITvx.x.x/Test_fast/README file
carefully (at least the beginning),
then read the beginning of the scripts 'Run'. Note that
it is a perl script.
To run the tests, simply issue :
(Run machine_name) >& log
where machine_name will usually be the name of your machine (any other character string is fine, however).
The script will create a directory whose name will be build from the machine name and today's date. All the results will be in that directory. The output files will be automatically compared, thanks to a 'diff' command, to a set of reference files, either from the plane_wave code (the corresponding difference files are prefixed by 'diff.'), or from a recent run of the ABINIT code (the corresponding difference files are prefixed by 'difnew.').
In addition to 'diff', another comparing tool called 'fldiff' -for 'floating diff'- is also used. It treats in a more clever way the comparison of floating numbers between the output files and the reference files. As used presently in the 'Run' script, for each run, only one single file, called 'fldiff.report', will be produced. If for one test case, the two files differ by the number of lines, the 'fldiff.report' file will report that it cannot compare the two files. Usually this problem will be seen at the level of 'command signs' appearing sometimes in the first column of the output files, so a typical error message (announcing something went wrong) will be:
Case_1
22
The diff analysis cannot be pursued : the command sign differ.
By contrast, it will identify the floating numbers and ignore their differences if they are within some prescribed tolerance (fldiff should become an expert system in this respect : for example, in the present version, it is already able to ignore most differences in timings). If everything goes fine for a test, fldiff should identify only the differences in :
Case_1
2
< Version 3.4.2 of ABINIT
> Version 3.4.0 of ABINIT
5
< Starting date : Tue 28 Jul 2002.
> Starting date : Mon 27 Jul 2002.
202
< +Overall time at end (sec) : cpu= 7.1 wall= 8.0
> +Overall time at end (sec) : cpu= 7.3 wall= 8.0
The fldiff.report file will have one such section for each Test_case that was run. It begins with the number of the test case, then includes a few blocks of three lines: the number of the line where something is happening, followed by the content of the two lines.
If differences (besides those described above) are found, then there is a problem, or the double precision tolerance needs to be adjusted (as time goes, this should become better). More information on the fldiff script can be found in the ~local_ABINITvx.x.x/Utilities/fldiff file. If needed, you can send by e-mail the fldiff.report to the ABINIT group for help understanding it and fixing possible bugs.
2) Test_v1 (for the sequential version only)
This directory contains tests built in the same spirit as those
in the Test_fast directory, but that exercise features not present in
the plane_wave code, like the treatment of metals, the GGA, the
new pseudopotentials, the multi-dataset mode, the cell parameters
optimization, and the spatial symmetry groups database.
These were developed during the development time of the version 1
of ABINIT.
Of course, the automatic difference procedure only compares to recent
runs of the ABINIT code. As for the 'fast' test cases, the fldiff.report
file is also available. 64 MB of memory should be enough for these
tests (with no other application running, however).
3) Test_v2 (for the sequential version only)
This directory contains tests built in the same spirit as those in the Test_fast directory, but that exercise features not present in the plane_wave code, nor in version 1 of the ABINIT package, mainly the response function features, and the use of the mrgddb and ifc codes. Again, the automatic difference procedure only compares to recent runs of the ABINIT code. As for the 'fast' test cases, the fldiff.report file is also available. 64 MB of memory should be enough for these tests (with no other application running, however).
4) Test_v3 (for the sequential version only)
This directory contains tests built in the same spirit as those in the Test_fast directory, but that exercise features not present in the plane_wave code, nor in version 1 or 2 of the ABINIT package, noticeably the use of the GW code. Again, the automatic difference procedure only compares to recent runs of the ABINIT code. As for the 'fast' test cases, the fldiff.report file is also available. 64 MB of memory should be enough for these tests (with no other application running, however).
5) Test_cpu (for the sequential version only)
This subdirectory contains the scripts, and input files needed for testing the cpu time, either on progressively finer real space grids, or on progressively bigger unit cells. Please read the README file of this directory. Also for this suite of tests, you have simply to issue
(Run machine_name) >& log
Unlike in the previous case, many directories will be created (more
than 10 in the present version). Their name begins with the test name (A1,
A2, A3, A4, B1, B2, B3, B4, C3, D3), and is followed by the machine name
and the date. Inside these directories, many runs are done.
There is a 'report' file that summarizes the timing of the different
runs, and there is a 'diff' file, that compares these timings with
the reference (output files from a PII at 450 MHz, usually).
The structure of these
tests is more complex than that of the Test_fast and Test_v1 directories.
The tools used are the 'serie' scripts (serieA,serieB,
serieC and serieD) as well as the 'getrep' script. For an explanation,
contact the ABINIT group.
For the largest tests (B and D series), up to 200 MB of central memory
are required.
6) Test_paral (needs both abinis and abinip)
This directory contains tests built in the same spirit as those
in the Test_fast directory, but that exercise the parallel version
of the ABINIT code.
The 'Run' script consider one of the different input files, and
for this file, it will perform first a sequential
run (using abinis),
then use the parallel code (abinip) with one processing node, then perform
different parallel runs with an increasing number of processing nodes.
As for the other series of test, the diff and the fldiff utilities
are used automatically.
Unlike the Run scripts in the other test directories, the present Run script is not a perl script, but a tcsh script. Note that it assumes that the tcsh shell can be found in /bin . If this is not the case, its first line must be changed.
7) How to run all the sequential tests, or a subset of these suited for developers ?
In the main directory, it is possible to issue
make tests_allseq >& log
in which case, all the tests in Test_fast, Test_v1, Test_v2, Test_v3, Tutorial, Test_cpu and the sequential tests of Test_paral will be issued. The choice of the name of the machine is not let to the user : it is "t3e" (even if you run on a PC !).
Also in the main directory, if you issue
make tests_dev >& log
the tests in Test_fast, Test_v1, Test_v2, Test_v3, and the sequential tests of Test_paral will be issued. As in the preceeding case, the name of the machine if fixed ("t3e"). In addition, a summary file, containing all the fldiff report files is created, then tarred and gzipped. It is given the name summary_tests.tar.gz, and might be sent by mail for examination.
Case 1 (source and tests) : you want to produce the file src_tests_x.x.x.tar.gz
Here, for example, we suppose that you have modified the code (in order to implement a new feature). This modification works, so it is time to synchronize with the main code. If the modifications are rather large, it is worthwhile to send your complete version to the ABINIT group.
First, you should give a version number to your version. Simply modify the appropriate variable in the Makefile file of your ~local_ABINIT directory. Then issue
make new_version_numberto touch the few routines that need this version number, then
make allseqas for the installation.
When you think everything can be frozen, you must issue
make src_testsThat's all ..
Case 2 (version for a specific platform) : e.g. you work on a SGI machine, and want to produce the file sgi_r10000_x.x.x.tar.gz
The requirements are : all executables (abinis, newsp and abinip) are working, and you have not erased one of the files needed for the tests, both sequential and parallel. Also, the version number is supposed correct (see above to modify it). In this case, simply issue :
make sgi_r10000For the sequential version only, or the parallel version only, use
make sgi_r10000_seqor
make sgi_r10000_parFor the other platforms, use the appropriate platform name, mentioned at the beginning of the present document, or obtained by typing
make dev
