So for this vendor and their software that would use a zIIP they are not included in the eligible time and hence not in any analysis of the eligible time. If that vendor is not Phoenix Software, then there are at least two that do this... TCBs when no zIIPs are present and Enclave SRBs when at least one zIIP is present. However, we are adding some new highly-parallel, SRB-mode-only algorithms to the parts of our code that are the highest CPU consumers that might cause us to reconsider this bifurcation. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
