-**Message Passing Interface (MPI): The Concept**+===== MPI =====
  
-----+OpenMPI is one implementation of the Message Passing Interface protocol, there is also MPICH2.  There are various applications which benefit by being parallelized:
  
-The MPI interface is meant to provide essential virtual topology, synchronization, and communication functionality between a set of processes (that have been mapped to nodes/servers/computer instances) in a language-independent way, with language-specific syntax (bindings), plus a few features that are language-specific. MPI programs always work with processes, but programmers commonly refer to the processes as processors. Typically, for maximum performance, each CPU (or core in a multicore machine) will be assigned just a single process. This assignment happens at runtime through the agent that starts the MPI program, normally called **//mpirun//** or **//mpiexec//**.+  * [[mpi:mpiblast|mpiBLAST]]
