Future
Some aspects of MPI's future appear solid; others less so. The MPI Forum reconvened in 2007, to clarify some MPI-2 issues and explore developments for a possible MPI-3.
Like Fortran, MPI is ubiquitous in technical computing, and it is taught and used widely.
Architectures are changing, with greater internal concurrency (multi-core), better fine-grain concurrency control (threading, affinity), and more levels of memory hierarchy. Multithreaded programs can take advantage of these developments more easily than single threaded applications. This has already yielded separate, complementary standards for symmetric multiprocessing, namely OpenMP. MPI-2 defines how standard-conforming implementations should deal with multithreaded issues, but does not require that implementations be multithreaded, or even thread safe. Few multithreaded-capable MPI implementations exist. Multi-level concurrency completely within MPI is an opportunity for the standard.
Improved fault tolerance within MPI would have clear benefits for the growing trend of grid computing.

Famous quotes containing the word future:
“The planet’s survival has become so uncertain that any effort, any thought that presupposes an assured future amounts to a mad gamble.”
—Elias Canetti (b. 1905)
“I would like you to understand completely, also emotionally, that I’m a political detainee and will be a political prisoner, that I have nothing now or in the future to be ashamed of in this situation. That, at bottom, I myself have in a certain sense asked for this detention and this sentence, because I’ve always refused to change my opinion, for which I would be willing to give my life and not just remain in prison. That therefore I can only be tranquil and content with myself.”
—Antonio Gramsci (1891–1937)
“I imagine, on the benches of an assembly, the most intrepid of thinkers, a brilliant mind, one of those men who, when they ascend the tribune, feel it beneath them like the tripod of the oracle, suddenly grow in stature and become colossal, surpass by a head the massive appearances that mask reality, and see clearly the future over the high, frowning wall of the present.”
—Victor Hugo (1802–1885)
