Intel® C++-Compiler

How should I do optimizations that speed and memory access cycles associated with Intel C++ compiler

My program have include a lot of loop with memory access. Now I use optimization that is O2 Maximize Speed. But should I use O3 Highest optimization instead. Also what else can I do adjustments

c++ compiler error on Mac OS X 10.9

When I compile the following hello world code using icpc on Mac OS X 10.9

#include<iostream>
using namespace std;

int main()
{
  cout<<"Hello World!"<<endl;
  return 0;
}

I get the following error message:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/5.1/include/stddef.h(29): error: expression preceding parentheses of apparent call must have (pointer-to-) function type

  #if !defined(_PTRDIFF_T) || __has_feature(modules)
