The z10 is a microprocessor chip made by IBM for their System z10 mainframe computers, released February 26, 2008. [1] It was called "z6" during development. [ 2 ]
IBM System z10 is a line of IBM mainframes. The z10 Enterprise Class (EC) was announced on February 26, 2008. On October 21, 2008, IBM announced the z10 Business Class (BC), a scaled-down version of the z10 EC. The System z10 represents the first model family powered by the z10 quad core processing engine.
IBM System z10. This generation of Z servers supported more memory than previous generation systems and can have up to 64 central processors (CPs) per frame. The full speed z10 processor's uniprocessor performance was up to 62% faster than that of the z9 server, according to IBM's z10 announcement, and included these other features:

IBM described MVPG as "moves a single page and the central processor cannot execute any other instructions until the page move is completed." [ 29 ] The MVPG mainframe instruction [ 30 ] ( M o V e P a G e, opcode X'B254') has been compared to the MVCL ( M o V e C haracter L ong) instruction, both of which can move more than 256 bytes within ...
HiperDispatch is a workload dispatching feature found in recent IBM mainframe models (the System z10 and IBM zEnterprise System processors and later models) running recent releases of z/OS. HiperDispatch was introduced in February 2008. Support was added to z/VM in its V6R3 release on July 26, 2013.

Typical implementations use more advanced codes, such as a BCH code, that can correct multiple bits with less overhead. Chipkill is frequently combined with dynamic bit-steering , so that if a chip fails (or has exceeded a threshold of bit errors), another, spare, memory chip is used to replace the failed chip.
