Nowadays, the rapid development of the SMP clusters provide a meaningful solution to enormously improve the ability for solving large scale problems in which MPI and Open MP mixed programming mode is used. In this paper, we present a hybrid programming implementation in Multilevel Fast Multipole Algorithm (MLFMA) to compute electro-magnetic scattering from extremely large targets. Message passing...
A series of novel RuO2/Ti electrodes were prepared by doping Pd, Co, Si elements into surface layer and introducing Sn-Sb coating as intermediate layer. Compared with RuO2/Ti electrode, these modified electrodes showed better electro-chemical properties and longer service-life. The doped elements had different effects on the electro-catalytic properties and service-life. The different modified electrodes...
In parallel computing, the memory requirement is an important problem, and in parallel software development, it is vital to optimize the memory management strategy. Programmers need to know the memory optimizing degree. But, the parallel programs' performance evaluation metric speedup only refers to computing time, without considering the memory cost when executing programs. In this paper, the relationship...
In the optimizing work of parallel program, especially in the realm of massively parallel computing, the parallel computing time and space must be concurrently carefully considered to cut down the computing time as much as possible, because lots of poor parallel space strategies would impact negative effects on computing time. Although, sometimes we have no choice but to sacrifice the space for the...
Multi-string matching requires to handle massive amount of data in pattern recognition, intrusion detection, and biological sequence analysis applications. This paper proposes a new algorithm to construct an optimal automation to achieve fast string matching. The algorithm consists of five steps: sorting, forming subtrees, encoding all subtrees, similarity checking, and completing all transitions...
