Here are some interesting things I've found so far. We're going to a P750, so won't be able to try out the "TurboCore" mode, but I think we will test different settings of the Intelligent Threads to see what works best for our workload: http://www.eweek.com/c/a/IT-Infrastructure/IBM-Unveils-Power7-Systems-Ramps-Up-Competition-Against-HP-Sun-490909/ "TurboCore mode is a workload optimization feature that can have four cores running, and putting the resources-include cache memory and memory bandwidth-of the other four dormant cores before those active ones. It also can increase the clock speed of those four active cores. Not all systems will support TurboCore mode. Among the four new servers, only the Power 780, designed for such high-end transaction workloads as databases, will support TurboCore. When not in TurboCore, all the Power7 systems are in MaxCore mode, which takes advantage of its increase in thread count. The chips also feature Intelligent Threads, a technology that can dynamically change the number of threads being run depending on the type of workloads." http://www-03.ibm.com/systems/power/hardware/750/index.html "Intelligent Threads technology enables workload optimization by selecting the most suitable threading mode: Single Thread (per core) or Simultaneous Multi Thread-2 or 4 modes" IBM Redbooks and analysis: http://mcpressonline.com/analysis/analysis-of-news-events/ibm-releases-redpapers-on-new-power7-servers.html ________________________________ Privileged/Confidential Information may be contained in this message or attachments hereto.
