Hi there, after installing the latest Update to the Intel C++ Compiler ( 2013.2.149 ), it seems like the option /MP ( Multi processor compilation ) has no effect anymore, e.g. the compilation is done one source file after the other. On our project this slows done compilation considerably. Can somebody confirm this? I am using Window 7 x64 Ultimate and have Visual Studio 2010 and 2012 with all latest updates installed. Its not difference if I use VS 2010 or VS 2012. Once I switch to the Microsoft Compiler, /MP seems to work just fine.
