『OpenStackの導入事例/検証事例のご紹介』NTTドコモ様 検証事例:OpenStack Summit 2014 Paris 講演「Design and Operation of OpenStack Cloud on 100 Physical Servers (NTT DOCOMO)」
講師:伊藤 宏通(日本仮想化技術 CTO)
先日パリで開催したOpenStack Summit 2014 Parisで講演した内容を日本語でお伝えいたします。
You will face many problems when you start designing your OpenStack Cloud because of a lack of full design architecture information. For example, there are many Neutron plugins, but it is difficult to choose the best plugin and its configuration to get a high throughput of a Virtual Machine (VM) and achieve a High Availability (HA) of L3 Agent. Also, we couldn’t find information for how much computing resource (CPU, Memory and HDD) is required for management and operation servers (e.g. API, RabbitMQ, MySQL and Monitoring etc.).
We built OpenStack Icehouse Cloud on 100 physical servers (1600 physical cores) without using commecial software, and did several performance and long-run tests to address these problems.
In this talk, we will present performance comparison of Neutron ML2 plugin implementations (Open vSwitch and Linux Bridge), tunnelling protocols (GRE and VXLAN) and physical network configurations (Network Interface Bonding and Server Side Equal Cost Multi Path) to achieve 10Gbps at a VM, and the L3 Agent HA we implemented. Also, we will present how much computing resource we used and each server loads to operate the cloud. Finaly, we will share our Ansible Based OpenStack deployment and management tool.
Key topics include:
- Performance comparison of OSS Neutron ML2 plugins (Open vSwitch and Linux Bridge) and tunneling protocols (GRE and VXLAN)
- Performance comparision of redundant network configurations (Network Interface Bonding and Server Side Equal Cost Multi Path)
- HA of L3 Agent (ACT/STBY) we implemented
- Ansible based deployment/operation tools
- Items we must watch for OpenStack operation
- Hardware specifications and resources we used to operate the Cloud
We will share a full design architecture and hardware sizing information for a large scale cloud and prove OSS based Neutron can handle a hundred servers.

Building managedprivatecloud kvh_vancouversummitmatsunota
In 2013, KVH began looking to broaden its market by offering more open cloud solutions besides VMware cloud to its customer base. KVH quickly settled on OpenStack as the foundation for a new type of managed private data center, but also wanted to create an environment where customers could easily place application workloads in any of its data centers. Today, using OpenStack and MidoNet, KVH offers managed a private cloud service for enterprises, all while meeting a wide range of their specific requirements and minimizing operation complexity.

【DLゼミ】XFeat: Accelerated Features for Lightweight Image Matchingharmonylab

概要:リソース効率に優れた特徴点マッチングのための軽量なアーキテクチャ「XFeat(Accelerated Features)」を提案します。手法は、局所的な特徴点の検出、抽出、マッチングのための畳み込みニューラルネットワークの基本的な設計を再検討します。特に、リソースが限られたデバイス向けに迅速かつ堅牢なアルゴリズムが必要とされるため、解像度を可能な限り高く保ちながら、ネットワークのチャネル数を制限します。さらに、スパース下でのマッチングを選択できる設計となっており、ナビゲーションやARなどのアプリケーションに適しています。XFeatは、高速かつ同等以上の精度を実現し、一般的なラップトップのCPU上でリアルタイムで動作します。
セル生産方式におけるロボットの活用には様々な問題があるが,その一つとして 3 体以上の物体の組み立てが挙げられる.一般に,複数物体を同時に組み立てる際は,対象の部品をそれぞれロボットアームまたは治具でそれぞれ独立に保持することで組み立てを遂行すると考えられる.ただし,この方法ではロボットアームや治具を部品数と同じ数だけ必要とし,部品数が多いほどコスト面や設置スペースの関係で無駄が多くなる.この課題に対して音𣷓らは組み立て対象物に働く接触力等の解析により,治具等で固定されていない対象物が組み立て作業中に運動しにくい状態となる条件を求めた.すなわち,環境中の非把持対象物のロバスト性を考慮して,組み立て作業条件を検討している.本研究ではこの方策に基づいて,複数物体の組み立て作業を単腕マニピュレータで実行することを目的とする.このとき,対象物のロバスト性を考慮することで,仮組状態の複数物体を同時に扱う手法を提案する.作業対象としてパイプジョイントの組み立てを挙げ,簡易な道具を用いることで単腕マニピュレータで複数物体を同時に把持できることを示す.さらに,作業成功率の向上のために RGB-D カメラを用いた物体の位置検出に基づくロボット制御及び動作計画を実装する.
This paper discusses assembly operations using a single manipulator and a parallel gripper to simultaneously
grasp multiple objects and hold the group of temporarily assembled objects. Multiple robots and jigs generally operate
assembly tasks by constraining the target objects mechanically or geometrically to prevent them from moving. It is
necessary to analyze the physical interaction between the objects for such constraints to achieve the tasks with a single
gripper. In this paper, we focus on assembling pipe joints as an example and discuss constraining the motion of the
objects. Our demonstration shows that a simple tool can facilitate holding multiple objects with a single gripper.
