基于向量运算，我们给出了插值曲面的完全显式解，保证了曲面的快速生成。 - The idea of combining the practical technique with parallel technique is presented and the parallelization of practical gmres is implemented . the corresponding serial and parallel programs are developed and different numerical tests are carried out . ( 4 ) a be sub - region parallel algorithm is presented
分析了经典gmres算法的复杂度和并行性，提出了实用化技术和并行化技术结合使用的思想，通过对矩阵向量运算的分布并行处理实现了实用化gmres算法的并行计算；编制了相应的串并行程序，进行了数值试验验证。 - Application component layer envelops the parallel algorithms of matrix - vector operation to offer users high - level interfaces ; the other three layers implement data abstraction 、 data partition and parallel mechanism respectively , and every layer has specific class and interface definition
其中应用组件层把矩阵向量运算的并行算法封装成类组件,为用户提供了高层次的接口;另外三层分别实现数据抽象、数据划分和并行机制支持三方面功能,每一层都有具体的类组件和明确的接口定义。 - Firstly , by selecting and defining the resource load indexes rationally , lbmr take into consideration the effect on the resource usage of source node and destination node by the migrant . by means of vector operations , lbmr can use multiply resources in harmony . secondly , lbmr adopts the smallest k - subset random algorithin , and the load index information is provided by the information cache
Lbmr算法的主要思想有三点：第一，基于合理选择和定义的资源负载向量，综合考虑进程迁移对源节点和目标节点资源利用率的影响，通过向量运算协调多种资源的平衡使用；第二，基于最小k子集随机算法，采用信息cache提供的负载信息作为负载平衡算法位置策略的选择依据；第三，基于进程生命时间的概率分布，根据迁移进程减速( slowdown )数学期望值的改善程度，选择适合于迁移的进程。 - The difference between these two algorithms is that the former uses sub - domain as the basic unit of task to be allocated and the latter uses the node - super - row as the basic unit of task . ( 6 ) the original problem is transformed into transformed domain by using laplace transform method . by the parallelization of the bem in the transformed domain , the parallelization of the elasto - dynamic be analysis is implemented by introducing the time related fimdamental solution , the time dependency is released from the formation of time - domain be equations
( 6 )通过拉氏积分变换法将弹性动力问题转换至变换域，通过变换域上边界元的分布并行处理实现了弹性动力边界元分析的并行化；引入与时间有关的基本解，解除了时域边界元系统方程组形成阶段的时间顺序依赖性，通过矩阵向量运算的分布并行处理实现方程组时间步进求解方法的并行化，这种方法是一种部分时间并行算法。
