To install and comfortably work with GNA, the following hardware and software resources are necessary:
Linux Fedora Core 4 or MacOS or Windows XP
Environment Java version 1.5 or later. The virtual machine proposed by SUN MicroSystems is available at http://java.sun.com.
512 Mb of RAM. GNA can run with less than 512 Mb of memory, but the size of the models that can be treated are reduced accordingly.
100 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, or with another Java virtual machine), but no guarantees can be given for these alternative configurations.
