Vector systems like SX-8 reach typically 50% of the peak performance in well tuned applications while massively parallel scalar systems crawl at less than 10% (no matter how much man power one invests in tuning). The effective performance of the SX-8 is much higher than that of BlueGene. The peak Linpack performance is meaningless, anyway. HPC Challenge benchmark makes a lot more sense for understanding what performance a machine can reach.
That's wrong. It needs FC switches like most of the SAN solutions. It has nothing to do with the crossbar interconnect. Implementation is completely different, true.

No, it runs SuperUX, a proprietary UNIX variant. GFS is NEC-GFS and has nothing to do with Sistina-GFS. Global File System is a too generic term...
