Entities edit
In a concurrent system, autonomous or semi-autonomous entities communicate to achieve the objectives of the system. Depending on the design, and entity may be called an
actor,
agent,
object,
producer,
process, or
routine. Here is a list of Tcl facilities and components that can be used to implement entities.
- coroutines
- generators
- iterators
- interp
- Each interpreter serves as an independent routine
- processes
- threads
Models and Paradigms edit
- communicating sequential processes
- A formal language for describing patterns of interaction in concurrent systems.
- flow-based programming
- event-driven programming
Systems in Tcl edit
The following Tcl systems provision concurrent routines, along with facilities for communication between them. See also
message passing for a list of systems that only distribute data.
- csp (package)
- Daerth
- Control minions of asynchronous threaded pipelined backpressure-mediated death stations.
- fiber
- Gotcl
- pipethread

Description edit
Tclonians typically focus on maintainability and related development issues. For a hard-core performance perspective on concurrency, see
The C10K Problem.
