ParaGeo can use parallel computation, allowing for domain decomposition for solving of big models. This may be performed without requiring additional data to be defined in the data file by executing the following command in the command prompt to run the parallel simulation:

 

mpiexec -n X parageo datafilename.dat

 

Where X  is the number of processors/nodes to be used for the parallel simulation.

 

Note that however there are data structures which allow more control on the simulation parallelization. In this section those are described:

 

•Parallel_control defining options for the parallel simulation such as domain decomposition algorithm, weighting of groups for domain decomposition, etc.

•Domain_definition_data allowing to pre-define the domain decomposition by providing the list of elements constituting each sub-domain

•Dom_grp_proc group processing data structure
