Re: V=R under Lpar on z890

Title: V=R under Lpar on z890

Coding the specification still works; it just doesn’t have any positive effect other than perhaps generating a message. As I understand it, the theory is that the processors are so much faster nowadays that there’s little/no benefit in V=R/V=F vs V=V on the newer boxes. Most of the hardware assists are no longer there, so they decided not to do it going forward.   So, I’d risk saying no, there’s not really much point in coding a V=R area any more.   Everyone,         I was under the impression that V=R was not supported on LPAR systems.         I see that V=F gets a message but the V=R works (seems to anyway) just fine.         Is there any benefit to V=R under LPAR?  (zVM 4.3  z890)
