18.0 beta includes several improvements which may result in compile-time reduction for part of your application. In several cases, such a reduction may be significant, and cut compile time by more than 50%. This change is across all optimization levels, and is primarily noticeable for applications with a large number of small functions. While compile time is improved, runtime performance should not be affected. We invite you to try the Intel Fortran and C/C++ compilers 18.0 beta, part of the Parallel Studio XE 2018 beta.
