The Intel® Composer XE for Windows*, Linux* and OS X* contains compilers and libraries for generating either IA-32 or Intel® 64 applications. The "Target Architecture Selection" dialog is used to specifiy the architecture your applications are targeting so the installation program will only install the relevant compilers and libraries.

When you profile your software with VTune™ Amplifier XE you often start from looking at the top function hotspots list. This allows you to see what functions are spending CPU resources, so you can focus your optimization efforts.

Function call counts can provide some additional information to assist in further optimization.

Problem

Link error with icpc: when linking object files compiled with icpc & g++* along with Boost* MPL library 1.51 or above, as shown in the sample test case below:

%cat t.h
#include <boost/mpl/vector.hpp>
template<typename T> struct my;
void foo(my<boost::mpl::vector<> >* = 0);

%cat u.cpp
#include "t.h"
int main() { foo();}
