With luck there an IBM Systems Journal article or redbook on the I-unit of current processors; if not, there should be. How does the cache work? Does MVS preserve the I-cache if a different thread is executing the same address (or share the I-cache between different CPUs)? Does it validate that the source of the cache is accessible whenever the SPKA is issued, i.e., does the cache have key and fetch protect bits? Any pre-executed instructions will have to be rolled back, correct? -- Binyamin Dissen <bdis...@dissensoftware.com> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
