NOTE 1: These machines the impetus for this document are being used for the calculation of low-frequency vibrational modes as part of Terahertz simulations.

The generic ethernet drivers being used cap the Maximum Transmission Unit MTU at bytes, whereas it should be possible to boost this number to Again, not necessary for the calculations to work, but a potential source of speed-up.

Why Ubuntu?

The author has had great success with it. Provided you start with a new hard drive or intend on wiping the machine clean as part of the installation , it is the easiest of the well-known Linux distributions to install that I am aware of.

There is one major issue with Ubuntu that OpenSuse , Fedora , etc. The Ubuntu installation CD installs everything programs, drivers, and libraries that the contents of the CD needs.


If you find yourself installing additional programs that have Ubuntu packages already configured for them here, using apt-get , the Ubuntu installation process will install all of the additional programs, drivers, and libraries required without you having to know what those additional packages are a very nice feature. The IFC-specific list was generated by successive error-and-install steps, with successive re-checks of IFC system dependencies required and additional apt-get operations performed before IFC would install without critical errors.

I suspect some non-computational chemists have found this tutorial simply because of the presented list of required IFC-specific apt-get installs. I attempted to compile MPICH2 for otherwise identical use for reasons related to message size errors in very memory-intensive INTENS calculations but after many, many trials, recompilations, and successful non-Crystal06 MPI test runs, I could never get Pcrystal to run 1 calculation on 16 nodes, only 16 separate serial calculations that would all write to stdout.

Ignoring the many details of Fortran compilation, libraries, etc.

The Portland Group Compiler, for which Crystal06 builds are also available, is available at an academic discount. The IP addresses will be the olde reliable NN IP scheme here to not explain it later.

Obviously, name this folder whatever you want avoiding spaces and crazy characters in the name and propagate the name changes in this document accordingly. It is installed as part of the Ubuntu CD installation, so it should be on your machine.

Terminal To a windows user, a Terminal window is one that will not close.

You should become familiar with moving around the Terminal window if you intend on doing any significant computational chemistry, as you will constantly be moving files, deleting files, renaming files, compressing files, and starting and canceling calculations.

The complication is due to Crystal06 being compiled bit and bit programs will not run in a bit OS unless several bit libraries are also installed. Whereas you set up the root user in Suse and Fedora as part of the installation process and set up the users separately , you set up an Administrator account during Ubuntu installation that is distinct from root with many, but not all, root privileges.

If you want to go the root route, check out help. You do not need to use sudo to make changes to files in your user directory, only to make modifications to system files which we will be doing in this document.

I use this A B convention in the document and you do NOT type these as they show up type only the text that follows as marked up in this document. Works for directories, too.

You probably do not need to update the installation, but you need the network connection working for apt-get anyway, so you might as well do a full system update. If you installed 8. In theory, you could do all of this without ever being online provided you have a machine online for downloading purposes.

The second letter can be any alphabet letter lower of upper case. It consists on a serie of k-points, identified by their respective caption, separated either by "-" minus sign or by " " empty space. For each group of two captions separated by a minus sign, the program will plot a band structure using all the appropriate k-points available in the database between the two corresponding k-points.

If you leave an empty space between two captions, the program will leave an empty space in the graph allowing you to plot many disconnected k-directions on the same graph. Note that all captions used to specify the band structure scheme must be de- fined in the special k-points section. The database contains a list of k-points reduced coordinates and associated en- ergy eigenvalues in eV.

The database key contains multiple informations regarding the system geometry and convergence criteria used to calculate energy eigenvalues of each k-point. In order for the band structure graph to be valid, it is important that all k- points plotted had their energy eigenvalues obtained from the same system and calculated using the same convergence criteria. Before adding any datas to the database, such a key is calculated for each dataset and compared to the database key.

STEP 3 : produce a. To produce a.

You will also be asked to enter the xmgrace launch command, which is the command you usually write in your shell to launch xmgrace default is xmgrace. Line color setup : Add the keyword -setlinecolor in the command line to choose the color of energy bands default is blue for the valence bands ; red for the conduction bands.

The 16 colors recognized by xmgrace are : white, black, red, green, blue, yellow, brown, grey, violet, cyan, magenta, orange, indigo, maroon, turquoise, green4 Line width setup : Add the keyword -setlinewidth in the command line to choose the thick- ness of energy band lines, Fermi energy line and separator lines default is 1 for energy band lines ; 1 for Fermi energy line ; 1 for separator lines.

Empty space s width setup : Add the keyword -setspacewidth in the command line to choose the percent- age of the total graph width to be occupied by empty space s , if any. Empty spaces are empty regions of the graph laid between disconnected k-directions in the band structure. Remember that you can place such empty spaces by putting a " " empty space instead of a "-" minus sign between two captions in the band structure scheme section of the.

Global setup : Add the keyword -setup in the command line if you want to perform a global setup and set all the available options mentionned above in the same run.Intel Fortran Compiler — software. It is used in the well-established Materials Project. From v If you already have conda installed, pymatgen can be installed from the matsci channel on Anaconda cloud using the following one line command: conda install --channel matsci pymatgen Pymatgen is under active development, and new features are added regularly.

If anybody is aware of other less empirical remedies to the same bug, or if someone noted other bugs linked to the use of the BLAS library provided with the Compaq TruUnix workstations, please let me know.

The database contains a list of k-points reduced coordinates and associated en- ergy eigenvalues in eV. Such calculations are currently only practical when performed in a multi-processor SMP , Beowulf , etc.
