Virtual Shared Memory Programming on Xeon Phi

Although nonshared memory programming is widely used in developing applications for the Xeon Phi coprocessor, the Intel C/C++ compiler supports virtual shared memory programming. The advantage of this programming model is that it allows you to have more complex data structures shared between the host and client, removing the requirement that the data objects be bitwise copyable (such that the data can be copied using simple memcpy function) between the host and the coprocessor. With virtual shared memory constructs, the data copied between the host and coprocessor can be arbitrarily complex, ...
