Run-time Support for Dynamic Load Balancing and Debugging in Paralex
Babaoglu, Ozalp; Alvisi, Lorenzo; Amoroso, Alessandro; Davoli, Renzo; Giachini, Luigi Alberto
Paralex is a programming environment for developing and executing parallel applications in distributed systems. The user is spared complexities of distributed programming including remote execution, data representation, communication, synchronization and fault tolerance as they are handled automatically by the system. Once an application starts execution in a distributed system, it may be interacted with at two levels: by Paralex itself to achieve automatic fault tolerance and dynamic load balancing; or by the user in association with performance tuning and debugging. In this paper, we describe the set of monitors and control mechanisms that constitute the Paralex run-time system and their use for implementing dynamic load balancing and debugging.
