Optimizing Without Breaking a Sweat

This article describes novel techniques developed to optimize DreamWork Animation's rendering, animation, and special effects applications without recompiling or relinking by preloading highly optimized libraries at run-time.

    • Putting -lm Before User Objects/Libraries on Link Line Can Impact Performance

    Recommended linking model: icc/icpc/ifort [user objs] [user libs] [sys libs] Using -lm (the GNU math library) prior to user-created objects or libraries causes the GNU libm to be used instead of the Intel math library, impacting performance.
