The use of virtualization technologies in high performance computing (HPC) environments
has traditionally been avoided due to their inherent performance overhead. However, with …

Virtualization presents both challenges and opportunities for HPC systems and applications.
This paper reviews them and also offers technical insights into two key challenges faced by …

Virtualization poses new challenges to I/O performance. The single-root I/O virtualization
(SR-IOV) standard allows an I/O device to be shared by multiple Virtual Machines (VMs) …

Cloud computing and virtualization technology have revolutionized general-purpose
computing applications in the past decade. The cloud paradigm offers advantages through …

Large-scale parallel computing is relying increasingly on clusters with thousands of
processors. At such large counts of compute nodes, faults are becoming common place …

Direct device assignment enhances the performance of guest virtual machines by allowing
them to communicate with I/O devices without host involvement. But even with device …

This paper explores the relationship between domain scheduling in avirtual machine
monitor (VMM) and I/O performance. Traditionally, VMM schedulers have focused on fairly …

Smartphones are increasingly ubiquitous, and many users carry multiple phones to
accommodate work, personal, and geographic mobility needs. We present Cells, a …

Virtual machine monitors (VMMs), including hypervisors, are a popular platform for
implementing various security functionalities. However, traditional VMMs require numerous …

Emerging fast, non-volatile memories (eg, phase change memories, spin-torque MRAMs,
and the memristor) reduce storage access latencies by an order of magnitude compared to …
