A new open-source SIMD vector libm fully implemented with high-level scalar C

Christoph Lauter
2016 2016 50th Asilomar Conference on Signals, Systems and Computers  
The error of all functions does not exceed 8 ulp, while a performance gain of up to 278.5% is obtained. Our library is fully free-standing, i.e. it does not depend on any other system library.  ...  As they depend on the scalar system libm for special case handling, the existing vector libms may induce a source of non-reproducibility.  ...  The maximum error of the functions provides stays well below 8 ulp, corresponding to accuracy requirements of High Performance Computing.  ...
