I haven't a clue what the data looks like but it is worth noting that Linux runs on the SGI Altix and the large Unisys machines, as well as large RISC machines. So 128+ cpus seems to work. It depends on your application and what it stresses but scalability isn't just a software issue. It is also a hardware issue, and the kernel can't scale linearly unless the hardware does as well.
