Calculating Smarandache function in parallel

This article presents an efficient method to calculate in parallel the values of the Smarandache function S(i), i = 1, 2, ..., n. The value S(i) can be sequentially found with a complexity of i/(log i). The computation has an important constraint, which is to have consecutive values computed by the same processor. This makes the dynamic scheduling methods inapplicable. The proposed solution is based on a balanced workload block scheduling method. Experiments show that the method is efficient and generates a good load balance.
