Abstract :
We propose a new parallel, noncollective I/O strategy called Distant I/O that targets clustered computer systems in which disks are attached to compute nodes. Distant I/O allows one sided access to remote secondary storage without installing server processes or daemons on remote compute nodes. We implemented this model using Active Messages and demonstrated its performance advantages over the PIOFS parallel filesystem for an I/O intensive parallel application on the IBM SP
