| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Distributed routing methods with small routing tables are scalable design on irregular networks for large-scale High Performance Computing (HPC) systems. Recently proposed compact routing methods, however, do not guarantee deadlock-freeness due to cycle dependencies. In this report, we propose a new method to assign virtual channels for each traffic. Infiniband technologies enable routers to switch virtual channels locally from an input port to an output port. Experimental results show that by using our VC assignment method we can reduce the average number of needed VCs by up to 63%. | |
