Visualisation specialist, Virtalis has developed the Virtalis Visionary Framework, a technology to get more value from PC clustering. Although the Visionary Cluster can act on its own, it can also be harnessed to PTC's high end, visualisation software, Division MockUp. When working in tandem in this way, Virtalis' 'MockUp on a PC Cluster' allows the manipulation of large data models. The new system requires only off-the-shelf PCs, rather than supercomputers, keeping both purchase and maintenance costs within reasonable bounds.
