Ways to Improve Performance

Profile-Based Optimization

Notice in the example above, that the +pgm option was necessary because the output file name differs from the instrumented program file name.

If you are using -rand C++ templates, check "Known Limitations" in the HP C++ Release Notes for possible limitations.

Restrictions and Limitations of PBO

This section describes restrictions and limitations you should be aware of when using Profile-Based Optimization.

•“Temporary Files”

•“Source Code Changes and PBO”

•“Profile-Based Optimization (PBO) and High-Level Optimization (HLO)”

•“I-SOM File Restrictions”

PBO calls malloc() during the instrumentation (+I) phase. If you replace libc malloc(3C) calls with your own version of malloc(), use the same parameter list (data types, order, number, and meaning of parameters) as the HP version. (For information on malloc(), see malloc(3C).)

Temporary Files

The linker does not modify I-SOM files. Rather, it compiles, instruments, and optimizes the code, placing the resulting temporary object file in a directory specified by the TMPDIR environment variable. If PBO fails due to inadequate disk space, try freeing up space on the disk that contains the $TMPDIR directory. Or, set TMPDIR to a directory on a disk with more free space.

Source Code Changes and PBO

To avoid the potential problems described below, PBO should only be used during the final stages of application development and performance tuning, when source code changes are the least likely to be made. Whenever possible, an application should be re-profiled after source code changes have been made.
