Processor Optimization

Processor Optimization for IA-32 only

The -tpp{5|6|7} options optimize your application's performance for a specific Intel processor. The resulting binary will also run on the other processors listed in the table. The Intel® C++ Compiler includes gcc*-compatible versions of the -tpp options. These options are listed in the gcc* Version column.

Option	gcc* Version	Optimizes for
-tpp5	-mcpu=pentium	Intel® Pentium® processors
-tpp6	-mcpu=pentiumpro	Intel Pentium Pro, Intel Pentium II, and Intel Pentium III processors
-tpp7	-mcpu=pentium4	Intel Pentium 4 processors, Intel Pentium M processors, and Intel Pentium 4 processor with Streaming SIMD Extensions 3 (SSE3)

Note

The -tpp7 option is ON by default.

Example

The following invocations all result in a compiled binary optimized for Pentium 4. The same binary will also run on Pentium, Pentium Pro, Pentium II, and Pentium III processors.

prompt>icpc prog.cpp

prompt>icpc -tpp7 prog.cpp

prompt>icpc -mcpu=pentium4 prog.cpp

Processor Optimization (Itanium®-based Systems only)

The -tpp{1|2} options optimize your application's performance for a specific Intel® Itanium® processor. The resulting binary will also run on the processors listed in the table. The Intel® C++ Compiler includes gcc*-compatible versions of the -tpp options. These options are listed in the gcc* Version column.

Option	gcc* Version	Optimizes for
-tpp1	-mcpu=itanium	Itanium processors
-tpp2	-mcpu=itanium2	Itanium 2 processors

Note

The -tpp2 option is ON by default.

Example

The following invocations all result in a compiled binary optimized for the Intel Itanium 2 processor. The same binary will also run on Intel Itanium processors.
