OpenCog CogServer

The OpenCog Cogserver is a network and job server for the OpenCog framework.

The main project site is at https://opencog.org

Overview

The CogServer provides a network server and a job scheduler. The network server provides a fast, efficient telnet interface, giving access to scheme (guile) and python command-lines. In particular, it is much faster (and more stable) than the native guile read-evaluate-print-loop (REPL) network server. Python does not even provide a networked REPL server.

Both can be used by multiple users at the same time, and provide not only a convenient interface for ad-hoc issuing of commands, but also provide a very good (and easy, and strong) way of doing bulk data transfers. In particular, the transfer of multiple megabytes of Atoms and (Truth)Values as UTF-8 (i.e. human-readable) data is easy and efficient. In particular, it does not require fiddling with complex binary formats or protocols or the use of protocol libraries or API's.

The job scheduler is an experimental prototype for controlling multiple threads and assigning thread processing priorities, in an AtomSpace-aware fashion. It is in need of the caring love and attention from an interested developer.

Building and Running

For platform dependent instruction on dependencies and building the code, as well as other options for setting up development environments, more details are found on the Building Opencog wiki.

Prerequisites

To build and run the CogServer, the packages listed below are required. With a few exceptions, most Linux distributions will provide these packages. Users of Ubuntu may use the dependency installer from the /opencog/octool repository. Users of any version of Linux may use the Dockerfile to quickly build a container in which OpenCog will be built and run.

cogutil

Common OpenCog C++ utilities http://github.com/opencog/cogutil It uses exactly the same build procedure as this package. Be sure to sudo make install at the end.

AtomSpace

OpenCog Atomspace database and reasoning engine http://github.com/opencog/atomspace It uses exactly the same build procedure as this package. Be sure to sudo make install at the end.

Building OpenCog

Perform the following steps at the shell prompt:

    cd to project root dir
    mkdir build
    cd build
    cmake ..
    make

Libraries will be built into subdirectories within build, mirroring the structure of the source directory root.

Unit tests

To build and run the unit tests, from the ./build directory enter (after building opencog as above):

    make test

CMake notes

Some useful CMake's web sites/pages:

-Wno-deprecated is currently enabled by default to avoid a number of warnings regarding hash_map being deprecated (because the alternative is still experimental!)
