In [[computing]], '''MIMD''' (multiple instruction, multiple data) is a technique employed to achieve parallelism. Machines using MIMD have a number of [[processors]] that function [[Asynchrony|asynchronously]] and independently. At any time, different processors may be executing different instructions on different pieces of data. MIMD architectures may be used in a number of application areas such as [[computer-aided design]]/[[computer-aided manufacturing]], [[Computer simulation|simulation]], [[Scientific modelling|modeling]], and as [[communication switches]]. MIMD machines can be of either [[shared memory]] or [[distributed memory]] categories. These classifications are based on how MIMD processors access memory. Shared memory machines may be of the [[Bus network|bus-based]], extended, or [[hierarchical#Computation and electronics|hierarchical]] type. Distributed memory machines may have [[Grid network|hypercube]] or [[Mesh networking|mesh]] interconnection schemes.
