Detailed Description

template<class TVar>
class parallel_assemble_task_t< TVar >

Iterações do laço podem ser executadas em paralelo.
.

• 1: Utilizar um parallel_for: (simples, mas não explora paralelismo entre threadassembly 1 e 2.
  
• 2: Utilizar árvore de tarefas: Podemos explorar o paralelismo entre threadassembly 1 e 2, mas
  O código pode ficar grande.
