Hardware, Embedded Systems SGI hopes by 2018 to build supercomputers 500 times faster than the most powerful today, using specially designed accelerator chips made by Intel. SGI hopes to bring a massive performance boost to its supercomputers through highly parallel processors based on Intel's MIC (many integrated cores) architecture.

The NUMA problems that are referring to assume that you only want to run a single application on the whole system. NUMA issues can be greatly reduced when you use something like CPUSETS to confine an application to a set of cpus/cores and memory. With a larger number of cpus/cores and CPUSETS, you can run a fair number of applications (depending upon the required number of cpus/cores) efficiently and with predictable completion times. Consequently, NUMA isn't a huge stumbling block. It all depends upon how you use the system.
