The SPM is accessed via a web page. While ultimately any web browsers will be able to access the system effectively, the current version is best accessed via Google Chrome web browser. Chrome is available via free download here. In addition, there are some more refined requirements:
A relatively recent desktop or laptop computer running the Windows, Mac OSX, or Linux operating systems. The current system has not been optimized for tablet or touchscreen operating systems or interfaces.
Mouse, track-ball, or trackpad-based input devise. The current system will not currently work well with tablet or other touchscreen devices.
