Known issues
- With the Intel Compiler 12.0.0 the compiler flag -no-prec-div and -np-prec-sqrt can lead to different results for same runs. Please don't uses these flags. Note that the flags will automatically set when using the compiler option -fast. In this case you should set -prec-div and -prec-sqrt.
