5.2 PGI Release 7.1 Compilers (32- and 64-Bit) for
Microsoft® Windows®
5.2.1 Invoking the Compilers
To translate and link SPECcpu2006 benchmarks with PGI Fortran, C, or C++ compilers the following
commands are used:
• pgcc -w invokes the PGI C compiler
• pgcpp -w invokes the PGI C++ compiler
• pgf95 -w invokes the PGI Fortran 90/95 compiler
5.2.2 Base Command-line Options
The best-known base switches for various benchmarks in SPECcpu2006 suite for 64-bit PGI Release
7.1 compilers for Linux on AMD Athlon™ 64 , AMD Opteron™ and AMD Family 10h processor-
based platforms. The following command-line options are used for base integer component of
SPECcpu2006 (CINT2006).

Notes:
1. Mathematical library (libm) required
2. Boost Library required
3. Smartheap libraries utilized. If the Smartheap libraries are not loaded, xalancbmk performs better with the
-Msmartalloc=huge:160 option.
