An Approach Toward MPI Applications in Wireless Networks
Elsa M. Macías, Álvaro Suárez, Vaidy S Sunderam · Kluwer Academic Publishers eBooks · 2005
Many emerging situations and applications demand the reconciliation of the MPI model, which implicitly assumes well-connected-ness and unform network capabilities, with wireless and mobile networks that are subject to variations and intermittent connectivity. We describe middleware extensions that assist applications operating in such environments by providing pre-emptive Quality of Service information. By exploiting this data, undesirable deadlock or indefinite blocking scenarios can be effectively avoided. Based on experimentation with an MPI based optimization application, we also show that good performance is retained while providing the added value of state information about communication channels.
