Emerging applications for data analytics and knowledge discovery typically have irregular or unpredictable communication patterns that do not scale well on parallel systems designed for traditional bulk-synchronous HPC applications. New network architectures that focus on minimizing (short) message latencies, rather than maximizing (large) transfer bandwidths, are emerging as possible alternatives...
With the increasing of software complexity in computing systems, more and more powerful mainframe computing systems begin to use Xen virtualization technology to split the system into several parts, making system maintenance much easier and more targeted while obtaining better operating efficiency. But precisely because of these different system parts running in different Xen-virtualized domains,...
We report our effort in engineering a high performance remote method invocation (RMI) mechanism for the Common Component Architecture (CCA). This mechanism provides a highly efficient and easy-to-use mechanism for distributed computing in CCA, enabling CCA applications to effectively leverage parallel systems to accelerate computations. This work is built on the previous work of Babel RMI. Babel is...
High speed machining technology is used in a broad range of applications to machine ferrous metals and nonmetallic material. Based on its application, a motorized high speed, high power/torque spindle is the key technology that drives high speed machining. Performance monitoring determines if the equipment is operating as expected. This paper presents a new motorized spindle performance monitoring...
