Not a fan of "magic" scaling across multiple servers. I'm not sure I would get the amount of control to squeeze the most performance out of this "OS" (edit: in terms of data locality for "big computation"). I am using Terracotta for a high performance JVM memory heap across a cluster. I need control and performance. I wonder how this compares... Personally, I'd rather stitch my cluster together than myself, rather than a monolithic "OS" hypervisor.
