To achieve the goal of supporting flexible, extensible and interoperable usage of heterogeneous performance distributed computing (HPDC) resources, we have developed the Distributed Application Runtime Environment (DARE) framework. DARE is a standards-based, abstraction-driven middleware layer that provides these capabilities.
At the core of DARE lies SAGA and SAGA-BigJob. SAGA-BigJob is a flexible general purpose pilot-job implementation, which has been shown to be a powerful abstraction for resource management. SAGA provides the interoperability layer. Combined, SAGA and SAGA-BigJob are used to support the resource management capabilities of many tools.
Furthermore, with a suitable Web development framework, DARE supports the development of a lightweight but extensible, science gateway capable of using a range of distributed resources. Currently, DARE uses DJANGO.
DARE is an example of a Platform Independent Library, with specific support for a range of commonly occuring "patterns" (namely stand-alone applications (Type I), pipelines of tasks (Type II) and execution patterns such as bag-of-tasks, coupled-ensembles etc (Type III)
The effectiveness of the DARE framework lies in providing a simple, scalable and sustainable
approach to developing and supporting a wide range of patterns of execution independent of the infrastructure, problem instance configurations and size.
