A teraflop/s computational capability is useless without data. The Intel Xeon Phi family supports a number of file systems including Lustre, NFS, Fraunhofer BeeGFS® (formerly FHGFS), and the Panasas® PanFS® file system. The chapter author, Michael Hebenstreit, also discusses the importance of a correct network setup. He notes in his chapter summary (courtesy Morgan Kaufmann):
This chapter provided the necessary information to create a cluster where Intel Xeon Phi coprocessors can be addressed as standard independent nodes in the network topology. Both network configuration and cluster file systems need to be addressed. With those components in place, utilizing distributed MPI programs running on the coprocessor can be as easy as recompiling them using the steps provided in this chapters’ introduction – though optimizing the programs to account for the specific computational capabilities and differences between processors and coprocessors in the cluster will still be another step.
