BTW - I applaud IBM's provision of the non-privileged ECAG instruction for obtaining cache characteristics. Here's the output of a little program I wrote to format the information it provides (on a Z13):
level 0: private data: line size=256, set associativity=8, total size=128K instruction: line size=256, set associativity=6, total size=96K level 1: private data: line size=256, set associativity=8, total size=2048K instruction: line size=256, set associativity=8, total size=2048K level 2: shared unified: line size=256, set associativity=16, total size=65536K level 3: shared unified: line size=256, set associativity=30, total size=491520K ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
