Energy Management; Ibm Energyscale Technology - IBM Power 780 Technical Overview And Introduction

to the IBM XL compilers, your applications can use the most recent industry-leading
optimization technology. For PL/I, it produces code that is intended to perform well across all
hardware levels, including POWER7+ of AIX.
IBM Rational® Development Studio for IBM i 7.1 provides programming languages for
creating modern business applications:
ILE RPG
ILE COBOL
C and C++ compilers
Heritage RPG and COBOL compilers
The latest release includes performance improvements and XML processing enhancements
for ILE RPG and ILE COBOL, improved COBOL portability with a COMP-5 data type, and
easier Unicode migration with relaxed USC2 rules in ILE RPG. Rational also released a
product named Rational Open Access: RPG Edition. This product opens the ILE RPG file I/O
processing, enabling partners, tool providers, and users to write custom I/O handlers that can
access other devices like databases, services, and web user interfaces.
IBM Rational Developer for Power Systems Software provides a rich set of integrated
development tools that support the XL C/C++ for AIX compiler, the XL C for AIX compiler, and
the COBOL for AIX compiler. Rational Developer for Power Systems Software offers
capabilities of file management, searching, editing, analysis, build, and debug, all integrated
into an Eclipse workbench. XL C/C++, XL C, and COBOL for AIX developers can boost
productivity by moving from older, text-based, command-line development tools to a rich set
of integrated development tools.
The IBM Rational Power Appliance solution provides a workload-optimized system and
integrated development environment for AIX development on IBM Power Systems. IBM
Rational Power Appliance includes a Power Express server preinstalled with a
comprehensive set of Rational development software along with the AIX operating system.
The Rational development software includes support for Collaborative Application Lifecycle
Management (C/ALM) through IBM Rational Team Concert™, a set of software development
tools from Rational Developer for Power Systems Software, and a choice between the XL
C/C++ for AIX or COBOL for AIX compilers.

2.14 Energy management

The Power 770 and 780 servers are designed with features to help clients become more
energy efficient. The IBM Systems Director Active Energy Manager uses EnergyScale
technology, enabling advanced energy management features to dramatically and dynamically
conserve power and further improve energy efficiency. Intelligent Energy optimization
capabilities enable the POWER7+ processor to operate at a higher frequency for increased
performance and performance per watt or dramatically reduce frequency to save energy.

2.14.1 IBM EnergyScale technology

IBM EnergyScale technology provides functions to help the user understand and dynamically
optimize the processor performance versus processor energy consumption, and system
workload, to control IBM Power Systems power and cooling usage.
On POWER7 or POWER7+ processor-based systems, the thermal power management
device (TPMD) card is responsible for collecting the data from all system components,
changing operational parameters in components, and interacting with the IBM Systems
