NuPIC Core

This repository contains the C++ source code for the Numenta Platform for Intelligent Computing (NuPIC). It will eventually contain all algorithms for NuPIC, but is currently in a transition period. For details on building NuPIC within the python environment, please see http://github.com/numenta/nupic.

Build and test NuPIC Core:

Important notes:

• For developers (contributing to NuPIC Core) please follow the Development Workflow steps.
• $NUPIC_CORE is the current location of the repository that you downloaded from GitHub.
• Platform specific Readme.md text files exist in some external/ subdirectories
• See the main wiki for more build notes

Using command line

Configure and generate build files:

mkdir -p $NUPIC_CORE/build/scripts
cd $NUPIC_CORE/build/scripts
cmake $NUPIC_CORE/src [-DCMAKE_INSTALL_PREFIX=../release]

Note: The -DCMAKE_INSTALL_PREFIX=../release option shown above is optional, and specifies the location where nupic.core should be installed. If omitted, nupic.core will be installed in a system location. Using this option is useful when testing versions of nupic.core with nupic (see NuPIC's Dependency on nupic.core).

Build:

cd $NUPIC_CORE/build/scripts
# optionally start a fresh build
make clean
make -j3

Note: The -j3 option specifies '3' as the maximum number of parallel jobs/threads that Make will use during the build in order to gain speed. However, you can increase this number depending your CPU.

Install:

make install

Run the tests:

cd $NUPIC_CORE/build/scripts
make tests_cpp_region
make tests_unit

Using graphical interface

Generate the IDE solution:

• Open CMake executable.
• Specify the source folder ($NUPIC_CORE/src).
• Specify the build system folder ($NUPIC_CORE/build/scripts), i.e. where IDE solution will be created.
• Click Generate.
• Choose the IDE that interest you (remember that IDE choice is limited to your OS, i.e. Visual Studio is available only on CMake for Windows).

Build:

• Open nupic_core.*proj solution file generated on $NUPIC_CORE/build/scripts.
• Run ALL_BUILD project from your IDE.

Run the tests:

• Run any tests_* project from your IDE (check output panel to see the results).
