Errr ??? I'm skeptical. Suppose the address is 0, relative to the base of the managed storage pool. What's its size? Which is the buddy?
I may be a bit hazy on the details. See http://en.wikipedia.org/wiki/Buddy_memory_allocation for something a bit more accurate. What I am not hazy on is the performance boost we achieved by implementing a scheme with Knuth's algorithm at its core. It cut the path length of a CICS GETMAIN or FREEMAIN from 2000+ instructions down to about 250. And doubled the transactional capacity of our app. John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
