Intel's chairman and CEO
demonstrates high-performance
Java optimization tool; new
VTune version 2.5 brings
Windows-based visual tuning to
Java developers
June 12, 1997
SAN JOSE, Calif.--(BUSINESS WIRE) via Individual Inc. -- Today
at the Netscape Developers Conference, Dr. Andrew S. Grove,
Chairman and CEO, demonstrated Intel's new VTune version 2.5
performance tuning tool with support for Java(a).
This is a first of its kind capability for Java. Now, Java tool
developers as well as Java program writers can optimize the
performance of their Java code in ways never before possible.
This is a critical capability in migrating Java from an exciting
technology to a mainstream language for ISV and corporate
application development.
VTune can graphically depict performance bottlenecks and offer
intuitive coding methodology suggestions to help programmers
optimize their Java code for the Intel Architecture. Grove showed
how the analysis portion of the tool enables programmers to zoom
in on the exact detail of these hot spots and then use the VTune
adviser to identify ways to optimize the section of code for better
performance.
"Intel Architecture provides the best price performance platform
for Java(b)," Grove said. "With the VTune 2.5 Java development
tool, developers and program writers will gain unique insight into
creating code that performs optimally on Intel processors"
Performance Optimization and the PC User
In his discussion on the evolution of the PC, Grove pointed out
that users desire more performance as they migrate to the Visual
Connected PC, and Intel sees Java as a key building block. "With
the expansion of visual computing, the performance of the
processor, the PC, and the software must increase more than ever
before," Grove said.
"Among new uses, we envision the PC routinely translating all
types of raw data into rich 3D models in seconds, helping users
better assimilate the information at hand. Interactive business
transactions, for example, conducted 'screen to screen' will
combine video, realistic graphics and audio to educate or
demonstrate new products or services to potential customers."
To meet those demands, PCs will need to deliver on three key
elements of microprocessor performance: floating point,
multimedia and integer. Intel processors, specifically the new
Pentium(R) II processor, deliver on all three levels of performance.
But Intel's role extends beyond the processors. "Intel's goal is to
make Java run best on Intel Architecture," Grove told developers.
"VTune for Java helps developers keep the pace with the ever
increasing performance capability of the processor."
VTune Environment
Unlike most profilers, VTune is not intrusive to a programmer's
code. It looks at all active software, including the operating
system, VxDs, and DLLs and examines each instruction as it
executes on the Intel Architecture. It gives information on the
amount of time the CPU spends in each active module and time
spent between system and user modes. Through a visual and
intuitive tuning methodology the programmer can also profile a
processor event, such as a cache miss, and study code down to
the microarchitectural level.
For Java, the new VTune version 2.5 allows the user to run
performance analyses at multiple levels: the system module, Java
class, Java method, Java source line and instruction. In addition,
"hotspots" functions or blocks of code that demand high CPU
resources can be identified in Native Java and JITed code and can
be analyzed down to the microarchitectural level. The tuning
advisor, or coach, provides processor specific hints to optimize
code for Pentium processors, Pentium processors with
MMX(TM) technology, Pentium Pro processors and Pentium II
processors.
VTune version 2.5 for Java will be available in August of this year.
