WebNov 16, 2012 · Kahan's summation algorithm is significantly more precise than straightforward summation, and it runs in O(n) (somewhere between 1-4 times slower than straightforward summation depending how fast floating-point is compared to data access. Definitely less than 4 times slower on desktop hardware, and without any shuffling … WebOur algorithm decreases the computation time significantly by applying integer arithmetic on floating-point data in the IEEE-754 standard or similar formats. We conducted experiments with synthetic data on a 32-processor Linux cluster; in the case of the internal sort alone, the Giga-byte sorting achieved approximately fivefold speedups.
