HP Caliper
HP Caliper 1.0 is a new general-purpose performance analysis and
performance improvement tool for Itanium-based applications bundled
with HP ANSI C, HP aC++, and HP Fortran 9x.
HP Caliper helps you analyze and improve the performance of your
native Itanium-based programs in three ways:
• A simple and quick way to optimize the performance of your program
by providing information for compiler profile-based optimization.
• Commands to measure the overall performance of your program.
• Commands to drill down to identify performance parameters of
specific functions in your program.
A significant advantage of HP Caliper is that it requires no special
compilation, link options, or libraries for your Itanium-based programs.
HP Caliper dynamically measures performance on:
• C, C++, and Fortran 9x binaries
• 32- or 64-bit binaries
• Shared or archive libraries
• Debug or optimized programs
Another advantage is that HP Caliper performs its measurements with
low overhead and for well-behaved executables, HP Caliper does not
alter the semantic behavior of the target program.
Required disk space is 12 MB. Memory requirements vary with settings
used for performance measurement.
