The application characteristics vary according to the input parameters. This is due to the difference in the usage of resources like network bandwidth, I/O and main memory, according to the input parameters. Effective execution of applications in a parallel computing environment that share such resources require some sort of adaptive mechanism to enable efficient usage of these resources. In our previous work, we have integrated GAMESS with an adaptive middleware NICAN (Network Information Conveyer and Application Notification) for dynamic adaptations during heavy load conditions that modify execution of GAMESS computations on a per-iteration basis. This leads to better application performance. In this research, we have expanded the structure of NICAN in order to include other input parameters based on which application performance can be controlled. The application performance has been analyzed on different architectures and a tuning strategy has been identified. A generic database framework has been incorporated in the existing NICAN mechanism so as to aid this tuning strategy.","PeriodicalId":329280,"journal":{"name":"2010 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum (IPDPSW)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116205180","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}

A major impediment, however, is the lack of a module linkage capability permitting hardware blocks to be compiled concurrently, limiting the effective use of multi-core and multiprocessor platforms. Although modular and incremental design flows can reuse the layouts of unmodified blocks, non-local changes to the logical hierarchy or physical layout, or addition of debug circuitry, generally force complete re-implementation. We describe the PATIS dynamic floorplanner, targeting development environments in which some circuit speed and area optimization may be sacrificed for improved implementation and debug turnaround. The floorplan consists of partial modules with structured physical interfaces observable through configuration readback rather than synthesized logic analysis circuitry, allowing module ports to be passively probed without disturbing the layout. Although PATIS supports incremental design, complete re-implementation is still rapid because the partial bitstream for each block is generated by independent and concurrent invocations of the standard Xilinx tools running on separate cores or hosts. A continuous background task proactively generates floorplan variants to accelerate global layout changes. The partial reconfiguration design flow is easier to automate in PATIS because run-time module swapping is not required, suggesting that partial reconfiguration may serve a useful role in large-scale static design.","PeriodicalId":329280,"journal":{"name":"2010 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum (IPDPSW)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114868236","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}

The demand for storage has not only changed in size, but also in speed, reliability and security. These requirements create a big challenge for storage system architects who aim for a one system fits all design. Storage policies like backup and security are typically set for an entire file system. However, this granularity is too large and can sacrifice storage efficiency and performance, particularly since different files have different storage requirements. In this work, we provide a framework for an attribute-based extendable storage system which will allow storage policy decisions to be made at file-level granularity and at all levels of the storage stack, including file system, operating system, and device managers. We propose to do this by using a file's extended attributes that will enable different tasks via plugins or functions implemented at various levels within the storage stack and provide a complete data-aware storage functionality from an application point of view. We provide examples of how our framework can be used to improve performance in a reliable clustered storage system.","PeriodicalId":329280,"journal":{"name":"2010 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum (IPDPSW)","volume":"C-35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126492654","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}

FG mitigates latency from disk-I/O and interprocessor communication by overlapping such high-latency operations with other operations. It does so by constructing and executing a coarse-grained software pipeline on each node of the cluster, where each stage of the pipeline runs in its own thread. The sorting program distributes data among the nodes to create sorted runs, and then it merges sorted runs on each node. When distributing data, the rates at which a node sends and receives data will differ. When merging sorted runs, each node will consume data from each of its sorted runs at varying rates. Under these conditions, a single pipeline running on each node is unwieldy to program and not necessarily efficient.We describe how we have extended FG to support multiple pipelines on each node in two forms. When a node might send and receive data at different rates during interprocessor communication, we use disjoint pipelines on each node: one pipeline to send and one pipeline to receive. When a node consumes and produces data from different streams on the node, we use multiple pipelines that intersect at a particular stage. Experimental results show that by using multiple pipelines, an out-of-core, distribution-based sorting program outperforms an out-of-core sorting program based on columnsort-taking approximately 75%–85% of the time-despite the advantages that the columnsort-based program holds.","PeriodicalId":329280,"journal":{"name":"2010 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum (IPDPSW)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125999246","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}
