8 1/2, pronounced otto e mezzo, is a high-level data-parallel language based on a new data structure: the fabric (initially called web). This fundamental data structure represents a field over a (discrete) piece of space-time. It is used in the simulation of dynamical systems. A fabric unify the concept of stream and collection and can be viewed either as a ``stream of collections'' or as a ``collection of streams''. The name come from the title of a Fellini movie.

* 8 1/2 programmes are hierachized through the concept of system.
* The 8 1/2 language is naturally a data flow, data parallel language.
* The 8 1/2 language is naturally a data flow, data parallel language.
* A static 8 1/2 programme (i.e. a programme involving only fabric with static shape) is detected by the interpreter and can be compiled (in sequential C or towards a SIMD abstract machine).
