I recently learned that C+11 <thread> support doesn't exist when using Intel Composer XE with versions of Visual Studio before 2012. I am posting this note for informational purposes.
Here is the message I received from Intel Premier Support:
Sorry for delay. I misunderstood your request. You were asking about the new <thread> support in C++11.
With Visual Studio 2010 and 2012 we support all Microsoft implemented C++11 features; in all other cases you need to specify /Qstd=c++11. However, in case of <thread> we don't have our own headers, so <thread> support is given only under VS environments that support <thread>. Obviously this is available with VS11.0 only, not earlier.
Does this help?
