SAGA: A standardized access layer to heterogeneous Distributed Computing Infrastructure

Distributed Computing Infrastructure is characterized by interfaces that are heterogeneous—syntactically and semantically. SAGA represents the most comprehensive community effort to date to address the heterogeneity by defining a simple, uniform access layer. In this paper, we describe the basic concepts underpinning its design and development. We also discuss RADICAL-SAGA which is the most widely used implementation of SAGA.
