In systems consisting of multiple clusters of processors which are interconnected by relatively slow communication links and which employ space sharing for scheduling jobs, such a...
Existing workflow management systems encapsulate the data and behavior of a process within its execution scope, preventing other processes from accessing this information until th...
Abstract— In this work, we demonstrate the power of providing a common set of operating system services to Grid Architectures, including high-performance I/O, communication, reso...
We present Gatekeeper, a decentralized protocol that performs Sybil-resilient node admission control based on a social network. Gatekeeper can admit most honest nodes while limiti...
Many parallel applications from scientific computing use MPI collective communication operations to collect or distribute data. Since the execution times of these communication op...
