Neal, R. M. (2015) ``Fast exact summation using small and large superaccumulators'', Technical Report, 22 pages: abstract, pdf.

The programs are written in C. Note that to compare with the methods of Zhu and Hayes you will need to get their programs, which are available as supplementary information for their paper.
