MockDistributedObject mocks the DistributedObject class. It should not be considered as part of the user interface.
MockDistributedObject
represents an object on a supercomputer that can have methods invoked on it (possibly) remotely; this is standard nomenclature in the HPC community, based on the idea that such objects get distributed among the cores/nodes on an HPC (even though each object typically lives on only one core). For example, an element of an array chare in charm++ is a mock distributed object, whereas the entire array chare is a collection of mock distributed objects, each with its own array index. MockDistributedObject
is a modified implementation of DistributedObject
and so some of the code is shared between the two. The main difference is that MockDistributedObject
has support for introspection. For example, it is possible to check how many simple actions are queued, to look at the inboxes, etc. Another key difference is that MockDistributedObject
runs only one action in the action list at a time. This is done in order to provide opportunity for introspection and checking statements before and after actions are invoked.
