Parallel numerical verification of the σ_odd problem

σ_{odd} problem
C++ (and OpenCL) implementations of sequential and parallel algorithms to check the σ_{odd} (sigma_odd) problem by the equivalent ς_{odd} (varsigma_odd) problem. Those are simple arithmetic conjectures like the iterative 3n+1 problem (Collatz conjecture), but they iterate a variant of the divisor function.
