As summer in the northern hemisphere is upon us, what better way to beat the heat and thunderstorms than grab a nice cool beverage, sit down, relax, and read upcoming four papers next week in this great issue!

For those CMGers in the southern hemisphere getting ready to endure winter, grab a hot chocolate, relax by the fireplace and do the same thing!

Here's a sneak peek of the CMG Summer Journal coming up next week!
  • z/OS SMT Measurements: Investigation and Explanation discusses IBM’s introduction of Simultaneous Multithreading (SMT) for z13 zIIP and IFL engines, written by Scott Chapman

  • Capacity Planning Revisited discusses the three main issues Terry sees in performance today, written by Terry Critchley

  • Performance Testing-Payments Engine discusses the challenges in performance testing programs which are migrating from mainframes to a heterogeneous middleware stack and explains the performance test methodology, implementation strategy & best practices to be followed taking mass & direct debit/credit payment engines as examples which are the prime candidate for these transformation programs, written by Girish Gundale and Rajan Lahiry

  • Understanding the Technology and Performance Implications of FICON Dynamic Routing is mainframe centric.  As part of the z13 announcement in January 2015, IBM announced support for a new FICON routing technique for FICON interswitch links (ISLs) called FICON Dynamic Routing (FIDR). This paper explains how the predecessor technology (static routing) works, compares it with the new FICON Dynamic Routing mechanism, and concludes with a discussion of the possible use cases where implementing FICON Dynamic Routing will be of the most benefit to z Systems end users, written by written by David Lytle and Steve Guendert

So get ready to log on to read the Summer issue as a CMG member benefit or apply for CMG Membership, here, to be able to access easily it when it arrives!
