Sun Microsystems SPARC T5220 - Manual (Page 37)

• Corestat — Corestat provides an on-line monitoring tool for core utilization of the
UltraSPARC T2 processor, providing a more accurate measure of processor and system
utilization than tools that only measure the utilization of individual threads.
Implemented as a Perl script and updated for UltraSPARC T2 processor awareness,
corestat aggregates instructions executed by all the threads on a single core,
revealing the cycles per instruction of key workloads and indicating where more
tuning is needed.
• Automatic Tuning and Trouble-Shooting System (ATS) — In the interest of
automating application tuning, ATS automatically re-optimizes and re-compiles
binaries with no need for source code. ATS identifies the inadequate optimization and
then automatically rebuilds the application with the correct options for optimization.
ATS is a plug-in for GCC4SS and Sun Studio 12.
Deployment
Cool Tools deployment elements provide applications that are already optimized for
CoolThreads technology, and save critical time in configuring systems for performance
and consolidation. Deployment elements include:
• CoolTuner — CoolTuner provides an on-site “virtual” tuning expert, delivering system
performance improvements by automatically applying current best practices
including both patching and tuning. Depending on administrator experience,
CoolTuner can save hours to weeks of effort tuning servers based on Cool Threads
technology.
• Cool Stack — Cool Stack represents a collection of the most commonly used free and
open source applications, pre-optimized for servers based on CoolThreads technology
running the Solaris OS. Including such popular applications as Apache, Perl, PHP,
Squid, Tomcat, and MySQL, these applications have been recompiled with Sun Studio
12 compilers to deliver a 30 to 200 percent performance improvement over standard
binaries compiled with GCC. Cool Stack applications also bring performance benefits
to any SPARC system.
• Consolidation Tool for Sun Fire Servers — Powerful Solaris Containers offer myriad
consolidation possibilities and the Consolidation Tool for Sun Fire Servers speeds their
deployment. With a wizard based GUI, this tool simplifies and automates the
installation of consolidated applications, enabling even novice administrators to
create a fully virtualized and consolidated environment using Solaris Containers. The
result is fast and high-quality consolidated deployments.

The software industry has traditionally offered point products that solve specific parts of
a problem, leaving it to customers to integrate those products into a solution that can
support their business applications. Organizations don’t purchase their operating
systems by assembling core components such as drivers, schedulers, command, and
