To install and comfortably work with GNA, the following hardware and software resources are necessary:
Linux kernel 3+, or MacOS X 10.8.3+ or Windows 7+ Operating System
2 Gb of RAM. GNA can run with less than 1 Gb of memory, but the size of the models that can be treated are reduced accordingly.
300 Mb of disk space to install the environment. Some additional disk space is needed for temporary files.
GNA has been tested with the configurations described above. This does not mean that it will not function in a different environment (e.g. with a different version of Linux, but no guarantees can be given for these alternative configurations.
