5 Implementation

A Distributed Maple Session
 

The architecture of a distributed Maple session is sketched in Figure 5. Each node connected to the session consists of two components:

Scheduler
A scheduler program manages the node interaction and schedules tasks among nodes. This program is implemented by a Java class library with main class dist.Scheduler and is independent of Maple. The initial scheduler process reads all application-specific information from the configuration file dist.systems and may then start instances of the scheduler on other machines with which it communicates via sockets.
Maple Interface
The package dist.maple running on each Maple kernel implements the interface between Maple and the scheduler. Communication between both components is based on pipes (named pipes for the Maple kernel connected to the user interface and standard input/output streams for the backend kernels).

During a session, additional socket connections between remote scheduler instances are dynamically established on demand.
