Using the TracerMP Class#
The TracerMP class is a multi-processing, thread-safe variant of the
Tracer class. It enables users to create multiple (distinct) instances of the
mapflpy_fortran object in separate processes, allowing for concurrent tracing operations
across multiple threads. the TracerMP branches new instances of the
mapflpy_fortran object into discrete processes and communicates with these instances through
python’s Pipe() protocol.
The Pipe() protocol requires that
the multiprocessing.connection.Connection is properly opened and closed to
avoid resource leaks. Therefore, it is recommended to use the TracerMP
class within a context manager (the with statement) to ensure that resources are
properly managed (or, alternatively, one can explicitly open and close the connection using the
connect() and disconnect() methods).
