Prezados colegas da lista, estava tentando rodar este exemplo quando tive problema de alocação de memória, alguém poderia me ajudar a resolver? Att, Ari Clecius Alves de Lima Engenheiro Químico Me.

Ari, 1 - Seu sistema Operacional é 32 bits. Mude para um de 64 . 2 - Então compre mais memora RAM 3 - Caso não funcione precisará aprender a fazer as coisas em paralelo. Abs e Boa sorte Em 23 de setembro de 2014 22:06, Ari Clecius <ari072000@yahoo.com.br> escreveu:
