We reduced the suffix array construction problem to a number of parallel primitives such as prefix-sum, radix sorting, random gather and scatter from/to the memory. Thus, the performance of the algorithm merely depends on the performance of these primitives on the particular shared memory ...
My idea about the problem is finding each occurrence of the end string and mark these in a array with a 1. Then prefix sum that array for range sum queries. After that on the suffix array of t+'#'+Sbegin iterate over the sorted suffixes which have Sbegin as a prefix to find how ...
We make use of the parallel primitives prefix sum, filter, and split. Prefix sum takes an array A of n elements, an associative operator ⊕ and an identity element ⊥ with ⊥⊕x=x for all x, and returns the array {⊥,A[0],A[0]⊕A[1],…,A[0]⊕A[1]⊕…⊕A[n−2]} as ...

In practice, this is done by first comparing each triplet against its predecessor, storing a flag of 1 whenever they are unequal, and then doing a prefix-sum of the list of flags. We use the same flagging method as Deo and Keely to tell if S12 are fully sorted (line 6 right and ...

In 1992, Gusfield et al. [8] presented the first optimal O(N+m2) time algorithm for the APSP using (generalized) suffix trees [21], where N is the sum of string lengths. This solution is optimal because the input size is N and the output size is m2. Almost 20 years later, Ohle...
The second algorithm improves the first algorithm to O(n) time and space in the worst case. The improved algorithm requires only 7n bytes of storage, including the n bytes for the original string, and the 4n bytes for the suffix array. We take a general divide and conquer approach: ...
