This paper presents the HMPI, a runtime system to integrate several MPI implementations, used to develop high performance applications that must run both in nodes with several operating systems and clusters of clusters infrastructures. HMPI has two different approaches to achieve this integration, using connection pools and HMPI daemons.

The MoDPAI tool was built because of the increasing decentralization of computational resources and the need for distributed and heterogeneous management systems. MoDPAI stands for the Portuguese phrase "monitoramento de dispositivos utilizando computacao pervasiva e agentes de software inteligentes". Its main goal is to assist network administrators in a great part of their tasks through automatic monitoring of devices. Combining the ideas of pervasive computing and software agents, this work presents a tool for monitoring devices distributed in a network and guided by a well-defined strategy. The tool uses intelligent software agents as the main monitoring mechanism.
