compile code with /MT option?

[knowdat]

In the user's guide for mkl 10 on chapter5 page 7, it says, "To use threaded Intel MKL, it is highly recommended to compile your code with the /MT option. The compiler driver will pass the option to the linker and the latter will load multi-thread (MT) run-time libraries."

As a background, I'm compiling a static fortran lib and linking that into a c++ dll compiled with visual studio, /MD, and libguide40.dll. What is the benefit to compiling the c++ code with /MT vs /MD?

Thank you,
Jon

/MT ought to be smaller, perhaps faster,than /MD, but the latter should have better diagnostics, if you are trying to trace events which occur ina Microsoftlibrary. I don't think that comment in the user's guide distinguishes between /MD and /MT; rather, it is meant to warn against mixing non-thread-safe libraries of past Microsoft 32-bit compilers with threaded code.
