SIMD prefix sum (cumulative sum)

711 Views

Colleagues,

Does anyone have a good reference to an implementation (or at least an algorithm) for implementing a so-called prefix sum (a cumulative sum) in Fortran using SIMD? I have found several good reference for implementations in C++ but they use SIMD functions peculiar to C++ that don't appear to be available in Fortran.
