-**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//**.

-HPC environments are often measured in terms of FLoating point OPerations per Second (FLOPS)

-**Condor**
-----
-Machines sit idle for long periods of time, often while their users are busy doing other things. **Condor takes this wasted computation time and puts it to good use**. The situation today matches that of yesterday, with the addition of clusters in the list of resources. These machines are often dedicated to tasks. Condor manages a cluster's effort efficiently, as well as handling other resources.
