“…The grant table mechanism of Xen provides an interface to virtual domains to optimize interdomain communication performance with a shared memory page. Inter-VM communication method (IVCOM) [43] applies a direct communication channel between Dom0 and a hardware virtualization-based VM (HV2M) and can greatly reduce VM entry/exit operations, which has improved HV2M performance. Zhang et al [44] pointed out that the virtual network Xen model has huge overhead due to the inefficiency of interdomain communications and privileged instructions (hypercall), and the network protocol stack.…”

In virtualized sensor networks, virtual machines (VMs) share the same hardware for sensing service consolidation and saving power. For those VMs that reside in the same hardware, frequent interdomain data transfers are invoked for data analytics, and sensor collaboration and actuation. Traditional ways of interdomain communications are based on virtual network interfaces of bilateral VMs for data sending and receiving. Since these network communications use TCP/IP (Transmission Control Protocol/Internet Protocol) stacks, they result in lengthy communication paths and frequent kernel interactions, which deteriorate the I/O (Input/Output) performance of involved VMs. In this paper, we propose an optimized interdomain communication approach based on shared memory to improve the interdomain communication performance of multiple VMs residing in the same sensor hardware. In our approach, the sending data are shared in memory pages maintained by the hypervisor, and the data are not transferred through the virtual network interface via a TCP/IP stack. To avoid security trapping, the shared data are mapped in the user space of each VM involved in the communication, therefore reducing tedious system calls and frequent kernel context switches. In implementation, the shared memory is created by a customized shared-device kernel module that has bidirectional event channels between both communicating VMs. For performance optimization, we use state flags in a circular buffer to reduce wait-and-notify operations and system calls during communications. Experimental results show that our proposed approach can provide five times higher throughput and 2.5 times less latency than traditional TCP/IP communication via a virtual network interface.

“…After it's done, the HVM resumes running (VM Entry). Compared with actual I/O handling cost, the VMX transition expense is huge Bai et al (2013). Specifically, When two VMs are performing an inter-VM communication, both VMs have to exchange data with Domain-0 first, then the data will be filtered and switched by the virtual bridge without sending them to the physical device.…”

Despite the rapid development and the wide use, virtualization confronts new challenges on improving network I/O performance. For virtual machines coexisted on a server, inter-VM network performance turns out to be worse than expected. Although many efforts have been dedicated to that issue on paravirtualized (PV) machines, HVMs (Hardware Virtual Machines) get less attention. However, co-resident HVMs are also suffering from low network I/O performance which troubles IaaS cloud infrastructure providers. Such problem is prominent as in the front-back network model several performance bottlenecks appear when inter-VM traffic is being handled. In this paper, we propose a novel approach and implement a prototype called "HV 2 M" to optimize inter-HVM network performance, which mainly address the throughput issues. HV 2 M takes advantages of the existing mechanisms for HVMs provided by Xen and is totally hardware independent. Unlike the existing idea, HV 2 M pushes data to the receivers without using

“…HPC systems built on multicore processors should provide excellent performance on shared memory, distributed memory and hybrids to parallel systems [8]. For example, the high-performance communication mechanism is vital in virtual machine (VM) networks [7], where VMs may be distributed or allocated to the same computer while performing one transactional task. As the authors mention in [9], it is greatly desired that performance of parallel applications would be predicted already at the design stage.…”

The goal of this paper is to give a specification of the software framework that evaluates the efficiency of different mechanisms for concurrent processes, notably process synchronization mechanisms. The paper discusses the concept of this framework, the potential users of it and some necessary considerations, including assumptions. Further, it defines general requirements for the framework and presents its desired conceptual design. The conclusions and possible directions for future work end the paper.
