Abstract	O principal objetivo da mineracao de dados e descobrir informacoes relevantes em conteudos digitais. O algoritmo Apriori e amplamente utilizado para este objetivo, mas sua versao sequencial tem baixo desempenho quando executado para grandes volumes de dados. Entre as solucoes para este problema encontra-se a implementacao paralela do algoritmo, e entre as implementacoes paralelas apresentadas na literatura com base no Apriori, destaca-se o DPA (Distributed Parallel Apriori). Este trabalho apresenta o algoritmo DMTA (Distributed Multithread Apriori), que se baseia no DPA, mas explora tambem o paralelismo em nivel de threads, a fim de aumentar o desempenho. Alem disso, o DMTA pode ser executado em plataformas de hardware heterogeneo, com diferentes numeros de nucleos de processamento. Os resultados mostraram que o DMTA supera o DPA, apresenta o equilibrio de carga entre processos e threads, e e eficaz nas atuais arquiteturas multicores.
