Abstract

One of the scarce resources that limits communication performance is buffer space on the network interface card. This becomes even worse when it is partitioned among several time-sliced processes. However, if gang scheduling is used, it is possible to swap buffer contents as part of the context switch, giving each job the full buffer space for the duration of its quantum. This does not suffer undue overhead, as the buffer space is mainly used to allow a larger flow-control window, and typically does not contain many packets that need to be stored.
