Finally HPX is a general purpose C++ Abstract — Technology trends indicate that exascale systems will runtime system for parallel and distributed applications of any have billion-way parallelism, and each node will have about three scale developed by Louisiana State University and Staple is a orders of magnitude more intra-node parallelism than today’s framework for developing parallel programs from Texas A&M. peta-scale systems. The majority of current runtime systems focus a great deal of effort on optimizing the inter-node parallelism by MATRIX is a many-task computing job scheduling system maximizing the bandwidth and minimizing the latency of the use [3]. There are many resource managing systems aimed towards of interconnection networks and storage, but suffer from the lack data-intensive applications. Furthermore, distributed task of scalable solutions to expose the intra-node parallelism. Many- scheduling in many-task computing is a problem that has been task computing (MTC) is a distributed fine-grained paradigm that considered by many research teams. In particular, Charm++ [4], aims to address the challenges of managing parallelism and Legion [5], Swift [6], [10], Spark [1][2], HPX [12], STAPL [13] locality of exascale systems. MTC applications are typically structured as direct acyclic graphs of loosely coupled short tasks and MATRIX [11] offer solutions to this problem and have with explicit input/output data dependencies. -

Parallel Data Mining from Multicore to Cloudy Grids
311 Parallel Data Mining from Multicore to Cloudy Grids Geoffrey FOXa,b,1 Seung-Hee BAEb, Jaliya EKANAYAKEb, Xiaohong QIUc, and Huapeng YUANb a Informatics Department, Indiana University 919 E. 10th Street Bloomington, IN 47408 USA b Computer Science Department and Community Grids Laboratory, Indiana University 501 N. Morton St., Suite 224, Bloomington IN 47404 USA c UITS Research Technologies, Indiana University, 501 N. Morton St., Suite 211, Bloomington, IN 47404 Abstract. We describe a suite of data mining tools that cover clustering, information retrieval and the mapping of high dimensional data to low dimensions for visualization. Preliminary applications are given to particle physics, bioinformatics and medical informatics. The data vary in dimension from low (2- 20), high (thousands) to undefined (sequences with dissimilarities but not vectors defined). We use deterministic annealing to provide more robust algorithms that are relatively insensitive to local minima. We discuss the algorithm structure and their mapping to parallel architectures of different types and look at the performance of the algorithms on three classes of system; multicore, cluster and Grid using a MapReduce style algorithm. Each approach is suitable in different application scenarios. We stress that data analysis/mining of large datasets can be a supercomputer application. Keywords. MPI, MapReduce, CCR, Performance, Clustering, Multidimensional Scaling Introduction Computation and data intensive scientific data analyses are increasingly prevalent. In the near future, data volumes processed by many applications will routinely cross the peta-scale threshold, which would in turn increase the computational requirements. Efficient parallel/concurrent algorithms and implementation techniques are the key to meeting the scalability and performance requirements entailed in such scientific data analyses. -
