Does prior installation of visual studio is required for working with Intel parallel studio XE2013 ? .
or Intel parallel studio and all its feature works with out Visual studio Installation?
Yes you need Visual Studio at least in it 2008 edition to be able to work with Parallel Studio.
No, iliyapolak, sorry but this is not correct. There is no requirement to have Visual Studio installed, it is optional. The tools in Intel(R) Parallel Studio XE have standalone GUI. Compiler doens't have its own GUI, but is available from command line without Visual Studio.
