This paper presents a new distributed computing framework for Many Task Computing (MTC) applications, based on the Extensible Messaging and Presence Protocol (XMPP). A lightweight, highly available system, named Kestrel, has been developed to explore XMPP-based techniques for improving MTC system tolerance to faults that result from scaling and intermittent(More)
This paper presents the results of using the Kestrel workload management system to test operating a Virtual Organization Cluster (VOC) across multiple sites. A Many-Task Computing (MTC) framework based on the Extensible Messaging and Presence Protocol (XMPP), Kestrel presents a special purpose scheduler that can offer better VOC scalability under certain(More)
This paper presents the results and experiences of adapting and improving the Many-Task Computing (MTC) framework Kestrel for use with bag of tasks applications and the STAR experiment in particular. Kestrel is a lightweight, highly available job scheduling framework for Virtual Organization Clusters (VOCs) constructed in the cloud. Kestrel uses the(More)
—In this short wild and crazy paper we argue that cloud computing has a lot to learn from current cybercriminals who plague the internet with botnets, malware, and viruses, with the intent of financial gain through extortion or exploitation. We present basic distributed system designs from the perspective of a hacker and argue that the same design features(More)
