Abstract

Even with Grid technologies, the main mode of access for the current High Performance Computing and High Throughput Computing infrastructures today is logging in via ssh. This mode of access locks scientists to particular machines as it is difficult to move the codes and environments between hosts. In this paper we show how switching the resource access mode to a Condor glide in-based overlay can bring together computational resources from multiple cyber infrastructures. This approach provides scientists with a computational infrastructure anchored around the familiar environment of the desktop computer. Additionally, the approach enhances the reliability of applications and workflows by automatically rerouting jobs to functioning infrastructures. Two different science applications were used to demonstrate applicability, one from the field of astronomy and the other one from earth sciences. We demonstrate …
