In pursuit of larger, more accurate tradespaces, engineers port existing serial design and evaluation codes onto ERDC's supercomputers. This results in a significant number of producer-consumer, file-mediated codes running simultaneously on Lustre, the distributed file system underlying our HPC systems. In this paper, we compare the performance of Lustre to Linux tmpfs, a shared memory file system that was designed for interprocess data transfer within a single node. Our results suggest that when conducting many file I/O operations in close succession, tmpfs offers tremendous speedup over Lustre-controlled disk storage. For tradespace applications, our results lend credence to a strategy of scheduling and organizing disparate codes in such a way to leverage tmpfs. We believe our results will help guide engineers at other national labs and scientists without HPC expertise to more easily port their I/O heavy serial codes to HPC systems.","PeriodicalId":91384,"journal":{"name":"Proceedings of the 2014 ACM Southeast Regional Conference","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84014758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motile cilia in the nasal and bronchial passages work to propel mucus and foreign matter from the respiratory system. Abnormal ciliary motion results in a wide spectrum of disorders. Currently, defective ciliary motion is diagnosed by visual examination of nasal biopsies for signs of dyskinesia. However, these examinations are highly subjective, lacking a \"common language\" of standardized quantitative metrics to describe the observed motion. Previous work relied on autoregressive representations of optical flow features that were fed into a support vector machine classifier. However, this approach was limited by two critical constraints: the strong parametric assumptions imposed by autoregressive models on the underlying structure of the data, and the requirement for experts to manually select regions of interest to be analyzed in the videos. Deep learning suffers from neither of these limitations. Feature maps are automatically generated from relevant portions of videos. Furthermore, the feed-forward architecture of convolutional neural networks do not impose the strong parametric assumptions of autoregressive models, permitting complex behaviors to be captured. Here, we demonstrate initial results in applying 3D deep convolutional networks to binary classification of ciliary motion. While our preliminary results lag behind those of previous work, there is considerable promise in deep learning for ciliary motion analysis and room for further experimental design.","PeriodicalId":91384,"journal":{"name":"Proceedings of the 2014 ACM Southeast Regional Conference","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89375263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MLFQ-based systems have the advantage of not requiring data to be saved and updated for each process after each burst of CPU time. Thus, the overhead computation time to run the scheduling algorithm is small. But MLFQs along with other algorithms risk starvation of those processes needing large CPU bursts, which drop down to the lowest-priority queue(N) of the stack of queues. This research extends previous work investigating the safety of reallocating a small quantity of CPU time from higher-priority queues to the final queue in order to prevent starvation called MLFQ-No Starvation (MLFQ-NS). This research explores an extension of MLFQ-NS with the new idea of Intelligent Mitigation (MLFQ-IM) which redirects time not just to the final queue Qn, but also to Qn-1, which is studied through simulation to understand its effectiveness and safety in reallocating a percentage of CPU time to the two lowest priority queues Queue(N) and Queue(N-1) when under heavy load, at and exceeding the maximum CPU processing capacity.","PeriodicalId":91384,"journal":{"name":"Proceedings of the 2014 ACM Southeast Regional Conference","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78780316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
