Further, the dispatcher is aware of data locality of the NUMA-local morsels and operator state, such that the great majority of executions takes place on NUMA-local memory.  ...  A third problem faced by many-core architectures is the decentralization of memory controllers, which leads to Non-Uniform Memory Access (NUMA).  ...  Abundant research in the 1990s into parallel processing led the majority of database systems to adopt a form of parallelism inspired by the Volcano [12] model, where operators are kept largely unaware  ...

A Survey On Data-Centric And Data-Aware Techniques For Large Scale Infrastructures

Silvina Caíno-Lores, Jesús Carretero
2016 Zenodo  
Currently, large scale data-intensive applications are hindered by the high latencies that result from the access to vastly distributed data.  ...  Recent works have suggested that improving data locality is key to move towards exascale infrastructures efficiently, as solutions to this problem aim to reduce the bandwidth consumed in data transfers  ...  As parallel file systems can significantly improve locality if designed with such purpose, there are examples of no-SQL database systems that aim to improve the overall efficiency of the data analysis  ...

Tiled-MapReduce

Rong Chen, Haibo Chen, Binyu Zang
2010 Proceedings of the 19th international conference on Parallel architectures and compilation techniques - PACT '10  
The prevalence of chip multiprocessor opens opportunities of running data-parallel applications originally in clusters on a single machine with many cores.  ...  Based on Tiled-MapReduce, we design and implement several optimizing techniques targeting multicore, including the reuse of input and intermediate data structure among sub-jobs, a NUCA/NUMA-aware scheduler  ...  Based on the observation, this paper proposed Tiled-MapReduce, that uses the "tiling strategy" to partition a large MapReduce job into a number of small sub-jobs and handles the sub-jobs iteratively.  ...

SCALER: Scalable parallel file write in HDFS

Xi Yang, Yanlong Yin, Hui Jin, Xian-He Sun
2014 2014 IEEE International Conference on Cluster Computing (CLUSTER)  
Two camps of file systems exist: parallel file systems designed for conventional high performance computing (HPC) and distributed file systems designed for newly emerged dataintensive applications.  ...  The N-1 (N-to-1) parallel file write is a critical technical challenge, because it is very common for HPC applications but HDFS does not allow it.  ...  SCALER improves upon this by adding HDFS inter-block and intra-block parallel file write support.  ...
