Code design

• Classes (mostly C++ with some C and Fortran) in shared dynamic libraries:

• • Main system libraries in directory $SIALIB;
  • Individual module (tool) libraries in $SIALIB/modules
  • • Some modules inherit or reuse other modules’ codes.

• Tools developed completely independently

• • They join the system automatically by including into $SIAHOME/modules tree;
  • No system “registry”.

• Typical (simple, “in-line”) application can be developed in 1-3 days.

• • Development can be carried out outside of the main $SIAHOME/modules directory tree

• Disco or SU codes can be ported in systematic manner.
