Resum
Fat-tree networks are the most popular topology among indirect networks in today's supercomputers. Current supercomputers are generally operated in a shared environment under the control of a job scheduler, executing many parallel applications simultaneously. The competition between these applications to use the same network resources causes a degradation in the applications' performance. The application that has to wait for the network resources occupied by another application's messages is sai...
