Exploring Use of the Reserved Core
John Holmen; Alan Humphrey; Martin Berzins SCI Institute and School of Computing, University of Utah, USA
Abstract
This chapter discusses application usage of the “reserved” core on an Intel Xeon Phi coprocessor through an examination of multiple thread placement strategies. In doing so, this chapter also seeks to extend discussion on less conventional thread management techniques when using a centralized scheduler model, and look at the interoperability of MPI and PThreads.
