要約(英語): Due to advent of powerful and easily available Multi core PC clusters, the computing power per node has been increasing significantly. On the other hand, installation and maintenance costs of powerful interconnection networks (Myrinet, Infiniband, etc.) are still expensive. Moreover, because they use nonstandard protocols and special device drivers, they tend to increase the specializations and complexities both in programming and in operability, and degrade portability. This paper proposes the portable method for improving the performance of bandwidth-oriented parallel applications by increasing the bandwidth without dedicated hardware, drivers, protocols, libraries and IEEE802.3ad (LACP). Since proposed method is introduced only by loading the proposed driver without any modifications to the TCP/IP protocol stacks and to existing applications, it has advantages in both high portability and stability. Proposed method also performs better than LACP, which is the most similar in comparison to proposal, without LACP supported switches and drivers. In addition, LACP performance is influenced both by the distribution algorithms implemented both in switches and in NIC drivers, and by the network parameters such as MAC addresses, IP addresses, VLAN id, etc. used in distribution algorithms. On the other hand, proposed method shows a stable effect regardless of them.
