Offload over Fabric overview
The Intel® Xeon Phi™ coprocessors x100, code named Knights Corner, support the offload programming model, allowing users to offload computations over PCIe and build heterogeneous applications. Such applications utilize the most prominent features of Intel® Xeon® processors and Intel Xeon Phi coprocessors at the same time. The most convenient way to create offloading programs is to use the Compiler Assisted Offload features of Intel® compilers (offload directives).
Currently Intel® Fortran Compiler for Windows projects created within Microsoft Visual Studio* just support "Native Only" option in "Debugger Type" setting (see Figure 1). If your project is a Fortran main program calling a managed DLL you will not be able to debug your Fortran code into managed code source line starting from your application.
