A latency-hiding algorithm for the parallelization of large scale agent-based model simulations (ABMS) on parallel/distributed computing platform is proposed. The key idea of this algorithm is using redundant computations to hide communication latencies. An analytical model for this algorithm is presented to tell how to select R value to reach the best speedup. Compared to B+2R algorithm [1], theoretical...
Clock skew scheduling is an efficient technique to minimize the cycle period by properly assigning clock delays to registers in a circuit. But its effectiveness is limited by the difficulty in implementing a large number of arbitrary clock skews. Multi-domain clock skew scheduling and prescribed-domain clock skew scheduling are two alternatives to overcome this shortage by restricting the number of...
In this paper, we present a complete framework for celltype selection in modern high-performance low-power designs with library-based timing model. Our framework can be divided into three stages. First, the best design performance with all possible cell-types is achieved by a Minimum Clock Period Lagrangian Relaxation (Min-Clock LR) method, which extends the traditional LR approach to conquer the...
In this paper, we propose a fast greedy search algorithm for optimal single-cycle signal timing at individual oversaturated intersections. We illustrate the efficiency of the algorithm with a numerical example in the literature.
Clock skew scheduling is an effective technique to improve the performance of sequential circuits. However, with process variations, it becomes more difficult to implement a large number of clock delays in a precise manner. Multi-domain clock skew scheduling is one way to overcome this limitation. In this paper, we prove the NP-completeness of multi-domain clock scheduling problem, and design a practical...
Data consistency is an important problem for mobile e-commerce networks. Based on the analysis of traditional algorithms, a novel distributed mobile data consistency algorithm called DCAM is proposed for mobile networks. The algorithm, which is constructed with read/write character and based on the token-asking algorithm, utilizes the Lamport's logical timestamps to ensure the time sequence and the...
