| Abstract(in English) | This paper proposes a fast calculation method of the set cover problem, which is implemented on reconfigurable processor DAPDNA-2 of IPFlex Inc. Content replication is a widely employed technique to improve the performance of large-scale content distribution systems. Replica placement method is derived from the set cover problem which is known to be NP-hard. It is difficult to caluculate the large-scale set cover problem on a program counter-based processor. Our proposed algorithm divides the combination optimally and performs pipeline operation. Experimental results show that the proposed algorithm reduces the execution time by 40 times compared to Intel Pentium 42.8GHz. |
