Abstract
We consider the problem of executing composite computing applications called on top of unreliable computing infrastructures. Having in mind the situation of the electric delivery in the sub-saharan area, we propose BEDWE, a decentralized workflow engine able to dynamically assign portions of the workflow to currently live compute nodes. More precisely, in a point-to-point manner, each node can receive a part of the workflow and delegate a subpart of it to another node. This mechanism can be repeated recursively until the whole workflow is executed. BEDWE includes a mechanism to support nodes leaving the network due to power outage. We present a software prototype of BEDWE and its experimentation over the French nation-wide Grid’5000 platform.
