Access Mode Address Space Switching
Submitted by z86VM on Sun, 06/28/2009 - 12:47.
Each OS process in z/Vos has to have its own address space. We recently created a primary address space DAT map for a z/VM CMS machine, as part of an experiment to test the effects of frequent access mode addres space switching. This works beautifully but we can't help but wonder about TLB cage rattling. We have been told that there are no tools capable of measuring TLB activity.
