I/O is the critical bottleneck for data-intensive scientific applications on HPC systems and leadership-class machines. Applications running on these systems may encounter bottlenecks because the I/O systems cannot handle the overwhelming intensity and volume of I/O requests. Applications and systems use I/O forwarding to aggregate and delegate I/O requests to storage systems. In this paper, we present...
Operating systems have historically been implemented as independent layers between hardware and applications. User programs communicate with the OS through a set of well defined system calls, and do not have direct access to the hardware. The OS, in turn, communicates with the underlying architecture via control registers. Except for these interfaces, the three layers are practically oblivious to...
