26th ieee International parallel and distributed processing symposium (IPDPS) / Workshop on High Performance Data Intensive Computing

作者： Kristensen, Mads Ruben Burgdorff Zheng, Yili Vinter, Brian Univ Copenhagen Niels Bohr Inst DK-1168 Copenhagen Denmark Lawrence Berkeley Natl Lab Berkeley CA 94720 USA

ISBN: (纸本)9780769546759

In this paper we propose a parallel programming model that combines two well-known execution models: Single Instruction, Multiple Data (SIMD) and Single Program, Multiple Data (SPMD). the combined model supports SIMD-style data parallelism in global address space and supports SPMD-style task parallelism in local address space. One of the most important features in the combined model is that data communication is expressed by global data assignments instead of message passing. We implement this combined programming model into Python, making parallel programming with Python both highly productive and performing on distributed memory multi-core systems. We base the SIMD data parallelism on DistNumPy, an auto-parallelizing version of the Numerical Python (NumPy) package that allows sequential NumPy programs to run on distributed memory architectures. We implement the SPMD task parallelism as an extension to DistNumPy that enables each process to have direct access to the local part of a shared array. To harvest the multi-core benefits in modern processors we exploit multi-threading in both SIMD and SPMD execution models. the multi-threading is completely transparent to the user - it is implemented in the runtime with OpenMP and by using multi-threaded libraries when available. We evaluate the implementation of the combined programming model with several scientific computing benchmarks using two representative multi-core distributed memory systems - an Intel Nehalem cluster with Infiniband interconnects and a Cray XE-6 supercomputer - up to 1536 cores. the benchmarking results demonstrate scalable good performance.

Modern multi-core and many-core systems offer a very impressive cost/performance ratio. In this paper a set of new parallel implementations for the solution of linear systems with block-tridiagonal coefficient matrix on current parallel architectures is proposed and evaluated: one of them on multi-core, others on many-core and finally, a new heterogeneous implementation on both architectures. the results show a speedup higher than 6 on certain parts of the problem, being the heterogeneous implementation the fastest. © 2012 ieee.

16th ieee/ACM International symposium on distributed Simulation and Real Time Applications

Porous media simulation is an important contribution in the study of many physical phenomena. the NoMISS greedy algorithm outstands from the existing sequential algorithms for constructing a pore subnetwork, in a relatively fast way. However, despite the NoMISS time reduction, there are still problems related to the required processing time when very large networks need to be studied. In this work, a non scalable parallel version of the NoMISS algorithm is presented, and a new approach is proposed to alleviate this issue;in both versions cluster cores work simultaneously on different porous subnetwork spaces. the first approach, named as Unbounded-NoMISS, allows the cores to go forward with the initialization of the porous subnetwork space, applying a balancing policy when a core needs more data. At the end, the cores require a sequential synchronization to finish the porous network construction. the second approach, named as Bounded-NoMISS, controls the porous subnetwork initialization by considering a site-size boundary, avoiding the final strong synchronization and improving considerably the scalability. the obtained results using a 125-core cluster are presented.

In this paper, we select the best two relays from a set of available relays, each of which is equipped with two antennas, based on the instantaneous path gains. Closed-loop quasi orthogonal space time block coding is then applied over the selected two relays to maximize cooperative diversity. parallel interference cancellation detection is also applied at the destination node to mitigate the problem of imperfect synchronization between the relay nodes. End-to-end bit error rate simulations confirm that the selection scheme yields a significant improvement in performance over the conventional scheme without using relay selection. Furthermore, the bit error rate simulations confirm the advantages of the detection scheme for a range of levels of asynchronism, and that only a small number of iterations is required in the parallel interference cancellation technique.

24th International symposium on Computer Architecture and High Performance Computing, SBAC-PAD 2012

Chapel is a parallel programming language designed to improve the productivity and ease of use of conventional and parallel computers. this language currently delivers sub optimal performance when executing codes that perform global data re-allocation operations on distributed memory architectures. this is mainly due to data communication that is done without aggregation (one message for each remote array element). In this work, we analyze Chapel's standard Block and Cyclic distribution modules and optimize the communication routines for array assignments by performing aggregation. thanks to the expressive power of Chapel, the compiler and runtime have enough information to do communication aggregation without user intervention. the runtime relies on the low-level GAS Net networking layer, whose versions of one-sided bulk put/get routines that support strides are particularly useful for us. Experimental results conducted on Hector (a Cray XE6) and Jaguar (Cray XK6)reveal that the implemented techniques can lead to significant reductions in communication time. © 2012 ieee.

Hydra Version Control System

Hydra Version Control System

International symposium on parallel and distributed processing with Applications, ISPA

作者： Christoph P. Neumann Scott A. Hady Richard Lenz Computer Science 6 (Data Management) Friedrich-Alexander-Universitat Erlangen-Nuremberg Erlangen Germany

the Hydra project offers version control for distributed case files in alpha-Flow. Available version control systems lack support for independent versioning of multiple logical units within a single repository each with its own version history and head. Our use case also requires mechanisms for labeling versions by their validity and for validity-based navigational access. Hydra is a multi-module and validity-aware version control system.

International symposium on parallel and distributed processing with Applications, ISPA

作者： Christoph P. Neumann Andreas M. Wahl Richard Lenz Computer Science 6 (Data Management) Friedrich-Alexander-Universitat Erlangen-Nuremberg Erlangen Germany

the α-OffSync project offers a synchronization concept for α-Flow, an electronic process support in heterogeneous inter-institutional scenarios in healthcare. A distributed case file is provided by α-Flow to represent workflow schemas as documents which are shared coequally to content documents. α-OffSync allows the detection and resolution of global concurrent modification conflicts on process artifacts based on locally available information by using logical timestamps. Further mechanisms are included to ease the management and dynamic extension of the group of participating actors.

New Scheduling Strategies and Hybrid Programming for a parallel Right-looking Sparse LU Factorization Algorithm on Multicore Cluster Systems

International symposium on parallel and distributed processing (IPDPS)

作者： Ichitaro Yamazaki Xiaoye S. Li Computational Research Division Lawrence Berkeley National Laboratory Berkeley CA USA

parallel sparse LU factorization is a key computational kernel in the solution of a large-scale linear system of equations. In this paper, we propose two strategies to address some scalability issues of a factorization algorithm on modern HPC systems. the first strategy is at the algorithmic-level, we schedule independent tasks as soon as possible to reduce the idle time and the critical path of the algorithm. We demonstrate using thousands of cores that our new scheduling strategy reduces the runtime by nearly three-fold from that of a state-of-the-art pipelined factorization algorithm. the second strategy is at both programming- and architecture-levels, we incorporate light-weight Open MP threads in each MPI process to reduce both memory and time overheads of a pure MPI implementation on many core NUMA architectures. Using this hybrid programming paradigm, we obtain a significant reduction in memory usage while achieving a parallel efficiency competitive with that of a pure MPI paradigm. As a result, in comparison to a pure MPI paradigm which failed due to the per-core memory constraint, the hybrid paradigm could utilize more cores on each node and reduce the factorization time on the same number of nodes. We show extensive performance analysis of the new strategies using thousands of cores of the two leading HPC systems, a Cray-XE6 and an IBM iDataPlex.
