The processor unit chip (PU chip) has 12 cores. The z15 cores support two-way simultaneous multithreading. [3]The cores implement the CISC z/Architecture with a superscalar, out-of-order pipeline.
Resource Measurement Facility (RMF) is a performance monitor for the z/OS operating system. It also collects data for long-term performance analysis and capacity planning. The product consists of the following components: Monitor I Data Gatherer which collects data in adjustable intervals from one minute to one hour.
Those users who stayed with IDMS were primarily interested in its high performance, not in its relational capabilities. It was widely recognized (helped by a high-profile campaign by E. F. Codd , the father of the relational model ) that there was a significant difference between a relational database and a network database with a relational ...
OMEGAMON, later IBM Tivoli OMEGAMON XE, is a software family of performance monitors for IBM zEnterprise computer environments. These products were originally written, marketed, sold and maintained by Candle Corporation, [1] which was acquired by IBM in 2004.
SMF data can be collected through IBM Z Operational Log and Data Analytics and IBM Z Anomaly Analytics with Watson. IBM Z Operational Log and Data Analytics collects SMF data, transforms it in a consumable format and then sends the data to third-party enterprise analytics platforms like the Elastic Stack and Splunk, or to the included operational data analysis platform, for further analysis.
Sunny Cove is used in the singular performance core (P-core) of Lakefield processors. [12] AVX and more advanced instruction sets are disabled due to the E-core not supporting them. Ice Lake-SP: server-only successor to Cascade Lake, using 10 nm process, released in April 2021 [5] [13] Cypress Cove Backport of Sunny Cove to Intel's 14 nm process
The IBM System z Application Assist Processor (zAAP), previously known as the zSeries Application Assist Processor, is a mainframe processor introduced by IBM in 2004. zAAP engines [1] are dedicated to running specific Java and XML workloads under z/OS, accelerating performance. zAAPs are available for zSeries 990 and 890 servers and later zSeries and zEnterprise models.
In 2015, the four core foundational CICS tools (and the CICS Optimization Solution Pack for z/OS) were updated with the release of CICS Transaction Server for z/OS 5.3. The four core CICS Tools: CICS Interdependency Analyzer for z/OS, CICS Deployment Assistant for z/OS, CICS Performance Analyzer for z/OS and CICS Configuration Manager for z/OS.
