HARDWARE --
Last month IBM announced the z13 micro-processor for their z13 mainframe computers. IBM claims the z13 is the "world's fastest microprocessor" and now with Linux 3.20 there's full support.

The z13 chip is a 5GHz octa-core processor while each mainframe can handle up to 141 processor cores, up to 10TB of RAIM memory, up to 320 separate I/O channels, and support for up to 8,000 virtual machines per system.. The z13 mainframes are a beast and now there's adequate support with the Linux 3.20 kernel.

The z13 support is coming via the s390 pull request. The s390 pull has the kernel build option for the z13 along with SMT support, cache snonym avoidance, CES5S crypto adapter support, and other z13 changes. There's also other s390 architecture changes via this pull request so hit up this link if you wish to learn more. If you're curious to learn more about the IBM z13, see the data sheet.
