PCL - The Performance Counter Library
Version 1.1, October 1998
PCL (The Performance Counter Library) is a common interface to access
performance counters built into modern microprocessors in a portable
way. PCL supports query for functionality, start and stop of counters,
and reading the current values out of the counters. Performance counting
can be done in user mode, system, and user-or-system mode. Functions
are callable from C, C++, and Fortran.
Currently, the following systems are supported:
- SUN Solaris 2.x with UltraSPARC I,II
- Linux 2.0.x and 2.1.x with Pentium/PPro/Pentium II
- Digital Unix with Alpha 21164
- Cray T3E with Alpha 21164
- SGI IRIX with R10000
- IBM AIX with PowerPC 604e
