  The Task System and Item Architecture (TSIA) is a model for transparent
application execution. In many real-world projects, a TSIA provides a simple
application with a transparent reliable, distributed, heterogeneous, adaptive,
dynamic, real-time, parallel, secure or other execution. TSIA is suitable for
many applications, not just for the simple applications served to date. This
presentation shows that TSIA is a dataflow model - a long-standing model for
transparent parallel execution. The advances to the dataflow model include a
simple semantics, as well as support for input/output, for modifiable items and
for other such effects.
