(SAGA) [43] and Transformer [44] are examples of such models, which try

to implement parallel models like MapReduce [42] and All-Pairs [45], taking

considerable burden off the application developer.

6.10.1.3 SAGA

Although MapReduce has emerged as an important data-parallel program-

ming model for data-intensive computing, most, if not all, implementations

of MapReduce are tightly coupled to a specic infrastructure. SAGA is a

high-level programming interface that provides the ability to create distrib-

uted applications in an infrastructure-independent way [38]. SAGA supports

different programming models ...
