I recently downloaded a copy of the Grid-Compliant Open Source Portals report from GridwiseTech. It is a comprehensive, yet very readable synopsis of GridSphere, Liferay and uPortal, all web-based applications that provide an “ease of use layer” to more in depth functionality. In the case of this particular report that includes grid functionality.While this report is certainly targeted at a particular audience it really reads quite nicely which means that you can determine quickly for yourself if you are indeed among that targeted audience.It also illustrates that the folks at GridwiseTech are quite good at these reports and I look forward to the next set. In fact, I think a report taking a common HPC type application and porting it to several different grid middleware options might be of particular interest. Technology Industry
