The Blue Gene/L was replaced by a Blue Gene/P in 2008. It is interesting to see that, at the beginning of the project, the most powerful supercomputer in Europe (for abour a month or so) was required. Now, only a few years later, more work can be done using only a few servers with accelerators. The SKA will ofcourse be a whole different challenge, which requires a completely different way of thinking about computing.

The SKA organization currently consist of Australia, Canada, China, Italy, the Netherlands, New Zealand, South Africa, and the UK. Other countries do participate in the development programs.
