CUDA acceleration for Xen virtual machines in infiniband clusters with rCUDA

Abstract

Many data centers currently use virtual machines (VMs) to achieve a more efficient usage of hardware resources. However, current virtualization solutions, such as Xen, do not easily provide graphics processing unit (GPU) accelerators to applications running in the virtualized domain with the flexibility usually required in data centers (i.e., managing virtual GPU instances and concurrently sharing them among several VMs). Remote GPU virtualization frameworks such as the rCUDA solution may address this problem.
