Abstract:
Amrita is a software system for automating numerical investigations.
The system is driven using its own powerful scripting language,
Amrita, which facilitates both the composition and archiving
of complete numerical investigations, as distinct from isolated
computations. Once archived, an Amrita investigation can later be
reproduced by any interested party, and not just the original
investigator, for no cost other than the raw CPU time needed to parse
the archived script. In fact, this entire lecture can be reconstructed
in such a fashion. To do this, the script: constructs a number of
shock-capturing schemes; runs a series of test problems; generates
the plots shown; outputs the LaTeX to typeset the notes; performs
a myriad of behind-the-scenes tasks to glue everything together.
Thus Amrita has all the characteristics of an operating system
and should not be mistaken for a common-or-garden code.
In this first lecture I will attempt to describe Amrita from the ground
up which, if successful, will be no mean feat given the scope of the system.
Particularly, since much of the material strays quite far from
traditional computational fluid dynamics into areas of heavy-duty
programming. Hopefully, my second and third lectures will convince
reluctant programmers that the excursion is worth the effort.
