On parallel processing where you have multiple types of processes, some of them seemingly hierarchical. The macro-tasks on a macro-task graph are assigned to processor clusters(PC) or processor elements(PE) by a static Active 4 years, 1 month ago. This paper presents a hierarchical parallel processing system for the multipass-rendering method. Home Browse by Title Periodicals The Journal of Supercomputing Vol. ... (hierarchical, compressed, whatever). If an internal link led you here, you may wish to change the link to point directly to the intended article. Each of them performs the computations assigned to them. I have seen improvements up to 20x increase in my applications. Request PDF | Hierarchical and Parallel Processing of Modulation Spectrum for ASR applications | The modulation spectrum is an efficient representation for describing dynamic information in signals. Hierarchical and parallel processing of modulation spectrum for ASR applications @article{Valente2008HierarchicalAP, title={Hierarchical and parallel processing of modulation spectrum for ASR applications}, author={F. Valente and H. Hermansky}, journal={2008 IEEE International Conference on Acoustics, Speech and Signal Processing}, year={2008}, pages={4165-4168} } Processing modulation frequencies channels with different classifiers provides a consistent reduction in WER (2% absolute w.r.t. from 45.8% to 43.9%) absolute w.r.t. Or if no research, how you would conceptualize of the situation. Parallel processing combines outputs of independent classifiers applied to different modulation frequency channels. I can't tell if it's even possible to have a "hierarchical parallel processing machine". Parallel computing is also called parallel processing. Is there straightforward method to take advantage of parallel processing in R within a HPC cluster to make my computations faster for Hierarchical clustering algorithm? The largest WER reduction is obtained through sequential processing moving from … 36, No. Processing modulation frequencies channels with different classifiers provides a consistent reduction in WER (2% absolute w.r.t. In this paper, we define a merit factor (MF), which allows for quantitative comparison of different possible implementations of data acquisition system. Hierarchical processing outperforms parallel processing. PLP baseline). The largest WER reduction is obtained trough sequential processing moving … This paper presents a hierarchical parallel processing system for the multipass-rendering method. Journal Article. Therefore, parallel processing is the most promising approach to the fast multipass-rendering method. The variation in WER in between the three combination schemes is approximately 1%. Processing laser beam images using parallel-hierarchical FPGA-based transformations. Parallel Processing:The simultaneous use of more than one CPU to execute a program. the single classifier approach. The largest WER reduction is obtained trough sequential processing moving … Parallel processing is the ability of the brain to do many things (aka, processes) at once. Viewed 708 times 5. The parallel processing outperforms the hierarchical processing. However, the method is also computationally expensive. Distributed sensor networks (DSN) often lead to high volumes of data to acquire and the implementation of the data acquisition is highly dependable on the application. Coarse grain task parallel processing This section describes a coarse grain task parallel pro-cessing scheme to decompose a sequential code to coarse grain tasks hierarchically and to generate hierarchical macro-task graph.
