CLUE: A Cluster Evaluation Tool

Description: Modern high performance computing is dependent on parallel processing systems. Most current benchmarks reveal only the high level computational throughput metrics, which may be sufficient for single processor systems, but can lead to a misrepresentation of true system capability for parallel systems. A new benchmark is therefore proposed. CLUE (Cluster Evaluator) uses a cellular automata algorithm to evaluate the scalability of parallel processing machines. The benchmark also uses algorithmic variations to evaluate individual system components' impact on the overall serial fraction and efficiency. CLUE is not a replacement for other performance-centric benchmarks, but rather shows the scalability of a system and provides metrics to reveal where one can improve overall performance. CLUE is a new benchmark which demonstrates a better comparison among different parallel systems than existing benchmarks and can diagnose where a particular parallel system can be optimized.

A performance analysis of Joseph Turrin's works for solo trumpet, a lecture recital, together with three recitals of selected works by J.S. Bach, E. Bloch, H. Tomasi and others

Description: This study addresses on facet of Joseph Turrin's compositional oeuvre: his published works for solo trumpet. Complete histories if all six trumpet compositions are chronicles. A discussion of formal organization and significant style features including harmonic language, melodic style and rhythmic features is included. A detailed performance analysis follows. The degree of difficulty of each work is assessed through an investigation of tessitura, range, melodic contour, endurance factors, fingerings, and technical features of the accompaniment. Analysis of tempi and dynamics, articulation and phrasing, and timbral considerations provides additional points of focus to the study. Finally, the importance of Turrin's works for trumpet and his impact on trumpet literature is assessed. Idiomatic aspects of composition that make Turrin's music attractive to performers are investigated and discussed.
