And manycore computing platforms with bsp++ smith and waterman proposed an exact in this paper, we propose and evaluate a parallel bsp strategy for executing . This paper presents a new smith–waterman implementation where the simd registers are parallel to the query sequence, but are accessed in a striped pattern like the .
Results in this paper we present what we believe is the fastest solution of the exact smith-waterman algorithm running on commodity hardware it is implemented in the recently released cuda programming environment by nvidia. Abstract this paper presents an efficient partial shape matching method based on the smith-waterman algorithm for two contours of m and n points respectively, the complexity of. 23 smith-waterman algorithm smith and waterman, 1981 ) for strings a and b and for mismatch scoring function s ( a , b ) and gap score, w i , the smith-waterman matrix h is. —the smith-waterman (sw) algorithm is one of the widely used algorithms for sequence alignment in computational biology with the growing size of the sequence database, there is always a need for even faster implementation of sw in this paper, we have implemented two recursive variable expansion . In this paper, we present a two-phase homology search algorithm for sirna off-target search that combines the effectiveness of blast concept and the thoroughness of smith-waterman algorithm.
Team number 2 1 smith-waterman local sequence alignment application for novo-g platform carlo pascoe, sunny gogar, and matthew gudwin, electrical engineering, university of florida. Motivation: the only algorithm guaranteed to find the optimal local alignment is the smith–waterman it is also one of the slowest due to the number of computations required for the search to speed up the algorithm, single-instruction multiple-data (simd) instructions have been used to . Sequence alignment based citation parser using blast and smith-waterman algorithm in this paper, we propose a new citation parser, called . In this paper, we design a new parallel algorithm which exploits the parallelism of the column of similarity matrix to parallelize the smith-waterman algorithm on a heterogeneous system based on cpu and gpu .
Synthesis of a parallel smith-waterman sequence alignment kernel into fpga hardware david greaves computer laboratory for this paper we focus on the smith-waterman. Smith-waterman is for local alignment, which means that if h(i, j) is 0, then it's best for the alignment to start there the first reference to the paper in pdf . The smith–waterman algorithm performs local sequence alignment that is, an arbitrary gap penalty was used in the original smith–waterman algorithm paper. The optimal traceback procedure for the smith-waterman algorithm using structural modelling techniques presents in this paper the proposed techniques been developed, compiled and simulated using altera quartus ii version 90 eda tools targeted to cyclone ii ep2c35 at 50mhz clock speed.

The smith-waterman algorithm is a key technique for comparing genetic sequences this paper presents a comprehensive study of a systolic design for smith-waterman algorithm.
The smith–waterman algorithm performs local sequence alignment that is, for determining similar regions between two strings of nucleic acid sequences or protein sequences . Empirically, we have found that gact gives an optimal result (identical to smith-waterman) with reasonable values of t and q algorithm the algorithm for extending sequences to the left is show below, reverse r and q for extending to the right:. Implementation of the smith-waterman algorithm on a reconfigurable supercomputing platform in this paper, we present the implementations of the smith-waterman . Due to its high sensitivity, the smith-waterman algorithm is widely used for biological database searches unfortunately, the quadratic time complexity of this algorithm makes it highly time-consuming the exponential growth of biological databases further deteriorates the situation to accelerate .
