The method of constructing a schedule for parallel algorithm execution is considered in the article. This algorithm takes into account the execution time of each operation of the algorithm and the relationship of operations on the data. The method is based on an information graph in which the nodes are the operations of the algorithm, and the edges are the directions of the data transfer. As a result of the interchange of operations between computing nodes, it is possible to achieve a reduction in the execution time of the algorithm by reducing the time spent on data transfer between computing nodes and reducing the downtime of computational nodes. The algorithm can be applied both in parallel programming and in adjacent areas, for example, when scheduling tasks in distributed systems.

Distributed optical fiber sensing system (DOFS) has great potential in areas of petroleum exploration and ocean defense. By algorithm optimization in different coding environment, the multi-point and real-time heterodyne demodulation of DOFS is achieved. In experiments, the length of the optical fiber is 500m, the spatial resolution is 5m and the system sampling rate is 200kHz, under which condition the data rate reaches up to 160MB/s and the system can stilled be demodulated timely. Based on this, by plotting the three-dimensional diagram (vibration intensity versus time and space), the whole DOFS can be detected continuously and accurately.

This paper provided a new high-precision spectrum analysis algorithm based on polyphase filter banks namely the double-path polyphase filter bank (DPPF) algorithm. The traditional single-path polyphase filter bank algorithm could be replaced by double-path polyphase filter bank algorithm, thereby making sub-channel transition bands of the first path fully coincide with sub-channel pass bands of the second path. Simulation results showed that the new algorithm had overcome the channelized digital receiver blind areas generated by D tunes decimation as well as realized high-precision real time spectrum analysis.

The use of the Walsh transform in DC-AC PWM waveform generation allows the calculation of the switching angles by means of linear equations which depend on the fundamental amplitude. However, when it is needed a wide regulation of the fundamental amplitude, conventional application of Walsh transform forces to switch among different equation sets, due to the range limitation of each one of them. In this paper it is described an advanced method to obtain the switching angles that permits full regulation of the fundamental amplitude, with only a switching interval vector, in single phase systems. The paper shows Matlab simulation results that proof the efficiency of the advanced method algorithm.

In the case of Joseon, the social development in the last millennium, the increasing aesthetic awareness, the admiration for Chinese literature and culture, the strong spread of advanced Chinese thought and culture, and the active exchanges between Joseon students and Chinese literati have provided the main soil for the emergence of literary theories in Joseon, and there are sufficient data to prove that Chinese literary texts and literary ideas have had an influence in Joseon. So far, numerous materials indicate that the formal essence and dialectical philosophical thought of Chinese literature have significantly influenced Korean culture and the mindset of Koreans. Moreover, in the process of fusion and evolution with Korean literature and philosophical thought, Chinese literature and philosophical ideas are influenced by native Korean culture, leading to variations. It can be said that without Chinese classical literature and philosophy, there would be no Korean classical literature and philosophy. Based on the evolution of Korean literature and the optimized ItemCF algorithm, this paper analyzes in depth the influence of Chinese classical literature on the literary creation of the Korean peninsula and accurately grasps the relationship between the origin and flow of Chinese and Korean classical literature. The experimental results indicate that the optimized ItemCF algorithm can accurately identify Chinese literary stories present in Korean literature, along with the underlying philosophical and dialectical ideas from Chinese literature. Moreover, through similarity analysis, the algorithm computes the potential evaluative value of Chinese stories within Korean literature, aiding in evaluating and analyzing philosophical and dialectical thinking within these narratives. The experiments prove that the optimized algorithm can significantly improve the data cleaning efficiency compared with ItemCF, and its user similarity matrix generation speed and efficiency are

This paper proposes a scheduling algorithm based on fast edge resource placement, so as to further improve the effect of bilateral resource integration of the mergers and acquisitions (M&A). Among them, the random demand model is taken as the basic resource scheduling method, and the algorithm is optimized by introducing edge computing and user random demand, thereby further improving the resource scheduling effect of mergers and acquisitions. The simulation results show that under different merger and acquisition resources, Zipf values, and types of resources, compared with traditional mean-based scheduling algorithms, the scheduling algorithm based on fast edge resource placement have higher resource scheduling benefits and significantly reduced time complexity. Therefore, it can be concluded that the scheduling algorithm based on fast edge resource placement has good performance, and it can carry out resource scheduling with good effect. In addition, applying the proposed algorithm in the actual enterprise M&A scenario can help enterprises to carry out better resource management, which is feasible and has certain practical application value.

Employing Machine learning algorithms in tactile sensing systems have emerged recently to recognize/classify touch patterns. The high computational complexity of the ML algorithms makes challenging the embedded implementation of tactile data processing. This paper proposes a complexity optimized tensorial-based machine learning algorithm for touch modality classification. The aim is to introduce an efficient algorithm minimizing the system complexity in terms of number of operations and memory storage which directly affect time latency and power consumption. With respect to the state of the art, the proposed approach reduces the number of operations per inference from 545 M-ops to 18 M-ops and the memory storage from 52.2 KB to 1.7 KB. Moreover, the proposed method speeds up the inference time by a factor of 43x at a cost of only 2% loss in accuracy.

A 512 node IBM Scalable POWERParallel Systems SP2 was installed at the Cornell Theory Center in October 1994. During the past couple of months we have Seen porting and optimizing code for carrying out lattice QCD calculations. Present performance is far from ideal, however, and optimization efforts are still under way. The rate limiting step in our code involves a rather generic inversion of. a large, sparse system, based on a partial differential equation in a multidimensional space. The insights we have gained so far may be useful in diagnosing performance in a wide class of applications. Copyright 1995 by the Association for Computing Machinery, Inc. (ACM).
