Technical information on ADF

Supported platforms

• We currently support a wide variety of modern Unix and Linux platforms,
  including Pentium/Athlon with Linux, SGI, HP, and IBM.
  We also support the Macintosh OS X platform and all popular Windows versions (2000, XP, Vista).
• If your favorite platform is currently not supported, contact us
  about the possibility to port ADF to this platform.
• As we provide precompiled executables, installation is straightforward.
• ADF uses either MPI or PVM for communication in parallel calculations.

Source code availability

The ADF and BAND programs are written in Fortran90, with small parts in C. Although limited parts of the package are distributed in binary form only, the majority of the code for ADF and BAND is available. This makes it possible to implement your own extensions, and to check in detail what the program does.

Hardware requirements

The amount of memory and disk space required depends strongly on the size of the molecule and the type of application. To give an indication, ADF may need a few times 100Mb of disk capacity for bigger calculations. For BAND the disk storage requirements tend to be considerably higher. The programs may run in as little as 32Mb memory for moderately sized systems. Preferably, one has 128Mb or more available, or more than 512 Mb in case of very large calculations (per CPU).
