Chapter 5  The JoCaml library

JoCaml core library Join provides the built-in types for channels and sites, and basic operations on those. Some additional modules are provided that capture common JoCaml programming patterns. All the following modules are automatically linked with the user’s object code files by the JoCaml compilers (Chapter 4).

• Module Join: JoCaml core library.
  • Sub-Module Site: site abstractions and failure control.
  • Sub-Module Ns: name service.
• Module JoinCom: producer/consumer interface.
• Module JoinCount: counting n events.
• Module JoinHelper: convenience functions to initiate applications with centralized name service.
• Module JoinFifo: concurrent fifo buffers.
• Module JoinMapRed: Map/reduce implementation based on pools.
• Module JoinPool: dynamic dispatch of work among registered agents.
• Module JoinProc: convenience functions to fork Unix comands.
• Module JoinTextProc: convenience functions to fork Unix commands oriented for text processing.

Some of Objective Caml modules are included in the JoCaml distribution.

• The core library Pervasives.
• The whole standard library.
• The Unix library. By contrast with Objective Caml, users programs are linked with the Unix library by default.
• The threads libraries are present in a different form. By contrast with Objective Caml, users programs are linked with one of threads library by default. All the functionalities of Objective Caml threads are present. However, users should probably refrain from creating threads explicitely.
• The Graphics library.
• The Dynlink library.

Other Objective Caml libraries are available through a companion Objective Caml system (see Section 4.1).
