GPU-Job Migration: The rCUDA Case
IEEE Transactions on Parallel and Distributed Systems, 2019Co-Authors: Javier Prades, Federico SillaAbstract:Virtualization Techniques have been shown to report benefits to data centers and other computing facilities. In this regard, not only virtual machines allow to reduce the size of the computing infrastructure while increasing overall resource utilization, but also virtualizing individual components of computers may provide significant benefits. This is the case, for instance, for the remote GPU Virtualization Technique, implemented in several frameworks during the recent years. The large degree of flexibility provided by the remote GPU Virtualization Technique can be further increased by applying the migration mechanism to it, so that the GPU part of applications can be live-migrated to another GPU elsewhere in the cluster during execution time in a transparent way. In this paper we present the implementation of the migration mechanism within the rCUDA remote GPU Virtualization middleware. Furthermore, we present a thorough performance analysis of the implementation of the migration mechanism within rCUDA. To that end, we leverage both synthetic and real production applications as well as three different generations of NVIDIA GPUs. Additionally, two different versions of the InfiniBand interconnect are used in this study. Several use cases are provided in order to show the extraordinary benefits that the GPU-job migration mechanism can report to data centers.

a live demo for showing the benefits of applying the remote gpu Virtualization Technique to cloud computing
IEEE ACM International Symposium Cluster Cloud and Grid Computing, 2017Co-Authors: Javier Prades, Federico SillaAbstract:Cloud computing has become pervasive nowadays. Additionally, cloud computing customers increasingly demand the use of accelerators such as CUDA GPUs. This has motivated that Amazon, for example, provides virtual machine instances comprising up to 16 NVIDIA GPUs. However, the use of GPUs in cloud computing deployments is not exempt from important concerns. In order to overcome many of these concerns, the remote GPU Virtualization Technique can be used. In this paper we present the design of a live demo to be used in exhibitions in order to show the benefits of using such a Virtualization Technique in the context of cloud computing systems. The demo was designed to be technically sound at the same time that it draws the attention of attendees. The demo was successfully used in the recent SuperComputing'16 exhibition, attracting more than 100 people to the booth.

We finally present the first results of an ongoing work consisting on applying the migration mechanism to the rCUDA remote GPU Virtualization framework.

wavnet wide area network Virtualization Technique for virtual private cloud
International Conference on Parallel Processing, 2011Co-Authors: Weida Zhang, Luwei Cheng, Choli WangAbstract:A Virtual Private Cloud (VPC) is a secure collection of computing, storage and network resources spanning multiple sites over Wide Area Network (WAN). With VPC, computation and services are no longer restricted to a fixed site but can be relocated dynamically across geographical sites to improve manageability, performance and fault tolerance. We propose WAVNet, a layer 2 virtual private network (VPN) which supports virtual machine live migration over WAN to realize mobility of execution environment across multiple security domains. WAVNet adopts a UDP hole punching Technique to achieve direct network connection between two Internet hosts without special router configuration. We evaluate our design in an emulated WAN with 64 hosts and also in a real WAN environment with 10 machines located at seven different sites across the Asia-Pacific region. The experimental results show that WAVNet not only achieves close-to-native host-to-host network bandwidth and latency, but also guarantees more effective VM live migration than existing solutions.

A framework of better deployment for WLAN access point using Virtualization Technique
24th IEEE International Conference on Advanced Information Networking and Applications Workshops WAINA 2010, 2010Co-Authors: Tsuyoshi Hamaguchi, Takuya Komata, Takahiro Nagai, Hiroshi ShigenoAbstract:Wireless network is common in the indoor and outdoor. One of the important problem is the better deployment of the access point for designing and constructing an efficient wireless network. Therefore, there are researches to determine the better deployment of access point. However, the considerations to fulfill the better deployment seem to be lacking in these researches. To keep the efficient wireless network, framework of better deployment for access point is necessity. Thus, we proposed Virtual Access Point(VAP) to be used for the better deployment of access point. VAP is a logical access point constructed by Virtualization Technique and independently keeps the configuration of wireless network in physical access point. VAP moves to another physical access point with executing live migration.
