In this paper, we assess the biological accuracy and relevance of XenoCluster results compared to a reported set of known xenologs in yeast (Hall et al. Eukaryot. Cell 4(6):1102-1115, 2005). We were able to assign a high-priority rank to all reported yeast xenologs for which we had sufficient genomic sequence data. Additionally, we now report on a fine-grained extension to our previous implementation (Walters et al. 8thinternationalparallelcomputingtechnologiesconference (PaCT), LNCS, vol. 3606, pp. 355-366, Springer, Berlin, 2005), in which we achieved 80% efficiency on 8 CPU cores. In the coarse-grained component, high degrees parallelism (up to 65x speedup on 4,096 processors) was reported. While an obvious candidate for coarse-grained implementation, this paper now describes a multiple granularity parallelism solution that includes exploitation of multicore shared memory nodes to address fine-grained aspects in the tree-clustering phase of our previous deployment of XenoCluster (Walters et al. 8thinternationalparallelcomputingtechnologiesconference (PaCT), LNCS, vol. 3606, pp. 355-366, Springer, Berlin, 2005).

the Optical Transpose Interconnection Systems (OTIS) is a well known hybrid optoelectronic interconnection networks preserves the modular and scalable behavior of the network. the OTIS hyper hexa-cell [17] is recently proposed recursive optoelectronic network (related to the family of OTIS/Swapped interconnection networks), combines the most desirable and attractive properties of both OTIS and hyper hexa-cell networks. We present and analyze, in this paper, the shortest path routing algorithms over dh-dimensional OTIS HHC network, for all combination of the pair of processors.

Many medical applications utilise distributed/parallelcomputing in order to cope with demands of large data or computing power requirements. In this paper, we present a new version of the XtremWeb-CH (XWCH) platform, and demonstrate two medical applicationsthat run on XWCH. the platform is versatile in a way that it supports direct communication between tasks. When tasks cannot communicate directly, warehouses are used as intermediary nodes between "producer" and "consumer" tasks. New features have been developed to provide improved support for writing powerfull distributedapplications using an easy API.

the paper introduces an example of a 'distributed tangible technology' as a new type of technology that enables children in different physical locations to engage in physical interaction. A virtual tug of war game is an example of a distributed tangible technology that is played by groups of children pulling a rope from two separate locations. the game was launched when teams in Finland and South Africa competed during an international science festival. the paper describes the design and implementation of the tug of war game. It explores the challenges combining tangible user interfaces withdistributedcomputing and distributedtechnologies to be overcome in future educational applications for children. Copyright 2009 ACM.

I/O for parallel and distributed systems has drawn increasing attention over the past decade as it has become apparent that I/O performance, rather than CPU performance, may be the key limiting factor in the performance of future systems. Prefetch is the fundamental approach for improving the overall read performance. In this paper, we study three parallel prefetching algorithms-LRU-Lookahead, Fixed Horizon, and Greedy algorithmin, and explore the performance characteristics of each of the algorithms using the trace-driven simulation.

In order to improve the performance of applications on OpenMP/JIAJIA, we present a new abstraction, Array Relation Vector (ARV), to describe the relation between the data elements of two consistent shared arrays accessed in one computation phase. Based on ARV, we use array grouping to eliminate the pseudo data distributing of small shared data and improve the page locality. Experimental results show that ARV-based array grouping can greatly improve the performance of applications with non-continuous data access and strict access affinity on OpenMP/JIAJIA cluster. For applications with small shared arrays, array grouping can improve the performance obviously when the processor number is small.

Withthe rapid development of information technology, the security of massive amounts of digital data has attracted huge attention in recent years. In this paper, we provide an efficient parallel implementation of the Advanced Encryption Standard (AES) algorithm, a widely used symmetrical block encryption algorithm, based on the Sunway TaihuLight. the Sunway TaihuLight is a China's independently developed heterogeneous supercomputer with peak performance over 100 PFlops. We also optimize the parallel implementation of the AES algorithm based on the Sunway TaihuLight to achieve more optimized performance. the optimization of the parallel AES algorithm in a single SW26010 node is provided. Specifically, we expand the scale to 1024 nodes and achieve the throughput of about 63.91 GB/s (511.28 Gbits/s). Our parallel implementation of the AES algorithm has great parallel scalability and the speedup ratio can be very high withthe number of nodes increasing.
Skeletal parallelism offers a good trade-off between programming productivity and execution efficiency. In this style of parallelism, an application is a composition of algorithmic skeletons. An algorithmic skeleton c...
