message sending operations
Blocking send of an array of values to a subdomain. Sends the values of array values to subdomain rank. The subdomain must perform a corresponding reception (the subdomain number must be that of this handler and the type and the size of the array must correspond) with the function recvValues(). The send is blocking.

non-blocking message sending operations
Sends an array of values to rank rank. Sends the values of array values to the instance of rank rank. The recipient must perform a corresponding reception (whose rank must be that of this handler and the type and the size of the array must correspond) with the function recvValues(). The send is blocking if is_blocking is true, non-blocking if it is false. In the latter case, the returned request must be used in waitAllRequests() or freed by freeRequests().

Detailed Description

Interface of the parallelism manager for a subdomain.

This manager provides an interface to access all functionalities related to parallelism.

Several possible implementations exist:

• sequential mode.
• parallel mode via MPI
• parallel mode via threads.
• mixed MPI/threads parallel mode. The choice of implementation is made when launching the application.

When an operation is collective, all associated managers must participate.

It is possible to create another manager from an instance containing a subset of ranks via createSubParallelMng().
