That technology is an intruder from the x86 line of processing. It it's a legitimate change, there should be a whole lot of explanation somewhere. In the IBM deployment, it might reside below the PoPs realm entirely. PCI seems to mean the same as in the x86 domain, thus an interface type for motherboard extension cards, including the PCI/e specification. Is PCI a PRQ? Does IBM still market facilities for x86 coprocessing within Z boxen? -- <not cent from sell> May the LORD God bless you exceedingly abundantly!
