zPDT used to support Power, but appears not to any more—none of the literature admits it exists. As for it eating into z hardware sales—yes, this has been the traditional problem: IBM seems convinced that people on z will never leave, and 25 years of attrition hasn’t convinced them otherwise. Many of us in the community would like to see them encourage small systems, on the “from tiny acorns, mighty oaks do grow” theory. Instead, the 64-bit MP3000 follow-on was killed, and zPDT/zD&T are redheaded stepchildren. I despair for IBM.

I’m sure this is not the case, because the IBM i OS and Linux can coexist on the same hardware. A final note, for the record: the article is typical El Reg garbage in that it completely misrepresents Moore’s Law anyway. The law is not about performance, it’s an observation that “the number of transistors in a dense integrated circuit doubles approximately every two years.” That end was seen coming long ago, has been wide discussed for years. The fact that execution optimization techniques may be reaching (or have passed) another limit is a different point entirely. It’s sort of like bemoaning the fact that automotive fuel economy hasn’t changed a lot in the last 20 years, while missing the point that cars are more reliable and much more powerful than they used were (ok, sort of the opposite point, but analogous): they’re *different* aspects—often intertwined, but far from the same. -- ...phsiii Phil Smith III Senior Architect & Product Manager, Mainframe & Enterprise Distinguished Technologist Micro Focus (Voltage) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
