The IDF threat at Tallil is rockets which are notoriously inaccurate. JAM has failed to hit anything important there in a long long time. There's really nothing to be concerned about.
The SGI Origin2000 scales up to 512 processors. XXL refers to the product ID for IRIX for the larger versions of the O2k. SGI Origin3000 scales up to 1024 processors but is only sold as an actual product up to 512 processors. SGI has sold O3k's with over 512 cpus in a single system image to some customers, such as NASA, but it's not treated as an actual product.
Standard IRIX therefor scales up to 256 processors on O2k and 512 processors with the XXL version. The only difference between the two is that drivers for the former might not work with the later because a few kernel structures changed. The same is true for the Origin3000 versions of IRIX.
