BCL-3 provides flexible and sufficient functionality to fulfill the commu- nication requirements of fundamental system software developed for DAWNING-3000 while guaranteeing security, scalability, and reliability. Important features of BCL-3 are presented in the paper, including special support for SMP and heterogeneous network environment, semi- user-level communication, reliable and ordered data transfer and scalable flow control. The performance evaluation of BCL-3 over Myrinet is also given.展开更多

Active Messages provide an efficient communication mecha nism with small overhead, which may expose the raw capabilities of the underlying hardware. In addition, one of the most promising techniques, user-level communi- cation, is often used to improve the performance of the traditional protocols such as TCP and UDP, and is also adopted in implementing the novel abstractions like Active Messages. Thus a user-level Active Messages model is designed and imple- mented on Dawning-1000. Preliminary experiments show that the combination of Active Messages mechanism and user-level communication technique is quite efficient in reducing software overhead associated with sending and receiving messages and in exploiting the capabilities of the interconnection network.展开更多
