Simulation of models within a distributed environment is facilitated. A model is partitioned based on clock domains, and communication between partitions on different processors is performed on synchronous clock boundaries. Further, data is exchanged across the network on latch boundaries. Thus, management aspects of the simulation, such as management associated with the global simulation time, are simplified. |

DETAILED DESCRIPTION The shortcomings of the prior art are overcome and additional advantages are provided through the provision of a method of facilitating processing of models in a distributed environment.
The method includes, for instance, obtaining a plurality of partition groups of a model to be processed, the plurality of partition groups corresponding to a plurality of clock domains; and adjusting a partition group of one clock domain to include at least a portion of another partition group of another clock domain, wherein communication between the partition group to be processed on at least one processor of the distributed environment and the another partition group to be processed on at least one other processor of the distributed environment is across at least one synchronous clock boundary.
In a further aspect of the present invention, a method of managing partition groups of a model is provided.
The method includes, for instance, obtaining a plurality of partition groups of a model, the plurality of partition groups corresponding to a plurality of clock domains; selecting from the plurality of clock domains an optimal clock domain; combining multiple partition groups of the plurality of partition groups into one or more combined groups; and providing at least a portion of a partition group corresponding to the optimal clock domain to at least one combined group of the one or more combined groups.
In yet another aspect of the present invention, a method of managing partition groups of a model is provided.
The method includes, for instance, obtaining a plurality of partition groups of a model, the plurality of partition groups corresponding to a plurality of clock domains; and adjusting one or more partition groups of the plurality of partition groups, wherein the adjusting for a partition group of the one or more partition groups includes moving at least a portion of a partition group of the plurality of partition groups to the partition group of the one or more partition groups
