Recent advances in the development of reconfigurable optical interconnect technologies allow for the fabrication of low cost
and run-time adaptable interconnects in large distributed shared-memory (DSM) multiprocessor machines. This can allow the
use of adaptable interconnection networks that alleviate the huge bottleneck present due to the gap between the processing
speed and the memory access time over the network. In this paper we have studied the scheduling of tasks by the kernel of
the operating system (OS) and its influence on communication between the processing nodes of the system, focusing on the traffic
generated just after a context switch. We aim to use these results as a basis to propose a potential reconfiguration of the
network that could provide a significant speedup.
