The paper deals with assessing performance improvements and some implementation issues of two well-known data mining algorithms, Apriori and FP-growth, in Alchemi grid environment. We compare execution times and speed-up of two parallel implementations: pure Apriori and hybrid FP-growth — Apriori version on grid with one to six processors. As expected, the latter shows superior performances. We also discuss the effects of database characteristics on overall performance, and give directions for proper choice of execution parameters and suitable number of executors.
