MCT is a set of open-source software tools for creating coupled models. MCT is
fully parallel and can be used to couple message-passing parallel models to
create a parallel coupled model. MCT is available as a small library and a set
of Fortran90 modules.

MCT provides model interoperability through a simple API. Two models that
declare and use MCT datatypes can be coupled with a minimum of effort.

MCT provides the following core coupling services:

   * a component model registry
   * domain decomposition descriptors
   * communications schedulers for parallel MxN intercomponent data transfer
     and MxM intracomponent data redistribution
   * a flexible and indexible (i.e., random-access) field data storage datatype
   * a time averaging and accumulation buffer datatype
   * a general spatial grid representation capable of supporting unstructured
     grids
   * parallel tools for intergrid interpolation implemented as matrix-vector
     multiplication spatial integration and averaging tools (including paired
     integrals to support conservative interpolation)
   * tools for merging data from multiple components for use by another
     component.
   * a programming model similar to that of the Message Passing Interface.

MCT can be used in single or multiple executable systems and allows sequential
or concurrent execution.
