- G-ICING is a data grid filesystem that aims to simplify access to distributed data grids through a familiar filesystem interface for Windows. It provides user and application transparency without sacrificing security or performance. - A usability study found that 9 out of 10 participants preferred G-ICING over traditional shell interfaces, finding it both faster (5-10x quicker) and easier to use. Tasks like editing documents and running jobs were much simpler through the filesystem paradigm. - While performance tests showed G-ICING could keep up with alternative solutions like Samba file shares, further work is still needed to optimize the system and expand what tasks it can support through the filesystem model.
