  • Best practices for managing Container Engine Clusters across multiple teams (Google Cloud Next '17)

    Your responsibility is to provide services for internal users. How do you run Google Container Engine (GKE) cluster(s) to enable multiple teams to run applications in a heterogeneous environment. Do you create a single cluster and partition with namespaces or do you create a cluster per team? For environments with multiple clusters, how do you federate access control? How do you ensure the right level of access for each cluster. This video will walk through some of the best practices associated with running GKE clusters in large team environments.

  • Star Clusters: Crash Course Astronomy #35

    Last week we covered multiple star systems, but what if we added thousands or even millions of stars to the mix? A star cluster. There are different kinds of clusters, though. Open clusters contain hundreds or thousands of stars held together by gravity. They’re young, and evaporate over time, their stars let loose to roam space freely. Globular clusters, on the other hand, are larger, have hundreds of thousands of stars, and are more spherical. They’re very old, a significant fraction of the age of the Universe itself, and that means their stars have less heavy elements in them, are redder, and probably don’t have planets (though we’re not really sure).

    Documentation, Source code, and EagleCAD designs: https://bitbucket.org/jkiepert/rpicluster Summary: The RPiCluster is a 33 node Beowulf cluster built using Raspberry Pis (RPis). During my dissertation work at Boise State University I had need of a cluster to run a distributed simulation I've been developing. The RPiCluster is the result. Each of the 33 RPi is overclocked to 1GHz and is running Arch Linux. This demo shows the RPiCluster running a parallel program I developed using MPI to control all of the RGB LEDs installed on each of the nodes. The Whole Story: The RPiCluster project was started in Spring 2013 in response to a need during my PhD dissertation research. My research is currently focused on developing a novel data sharing system for wireless sensor networks to facilitate i...

    Just wanted to show off my project I've been playing with over the past few weekends. It's a cluster of Raspberry Pi computers self contained inside of a portable toolbox. Specs: - 15x Raspberry Pi 2s @ stock 900MHz (60 total cores between them) - 15GB RAM (1GB each) - 240GB Flash storage (16GB x 15) - 300W Silverstone SFX power supply (only draws about 45W at the wall under full load) - 120mm exhaust fan - Arduino powered LED strip, because, uh... the 80s. Some benchmarks I ran using a multi-threaded python script I wrote that crunches stock price data stored on an external MySQL database on my network at home. This compares only 1 of the RPi 2 machines to an assortment of desktop PC processors I had laying around. You can essentially divide the RP2 number by 13 to get a rough est...

Documentation, Source code, and EagleCAD designs: https://bitbucket.org/jkiepert/rpicluster Summary: The RPiCluster is a 33 node Beowulf cluster built using Raspberry Pis (RPis). During my dissertation work at Boise State University I had need of a cluster to run a distributed simulation I've been developing. The RPiCluster is the result. Each of the 33 RPi is overclocked to 1GHz and is running Arch Linux. This demo shows the RPiCluster running a parallel program I developed using MPI to control all of the RGB LEDs installed on each of the nodes. The Whole Story: The RPiCluster project was started in Spring 2013 in response to a need during my PhD dissertation research. My research is currently focused on developing a novel data sharing system for wireless sensor networks to facilitate in-network collaborative processing of sensor data. In the process of developing this system it became clear that perhaps the most expedient way to test many of the ideas was to create a distributed simulation rather than developing directly on the final target embedded hardware. Thus, I began developing a distributed simulation in which each simulation node would behave like a wireless sensor node (along with inherent communications limitations), and as such, interact with all other simulation nodes within a LAN. This approach provided true asynchronous behavior and actual network communication between nodes which enabled better emulation of real wireless sensor network behavior. So, why I would want to build a Beowulf cluster using Raspberry Pis? The Raspberry Pi has a relatively slow CPU by modern standards. It has limited RAM, slow USB-based 10/100 Ethernet, and its operating system runs directly on a SD card. None of these "features" are ideal for a cluster computer! Well, there are several reasons. First, when your dissertation work requires the use of a cluster it is nice to ensure that there is one available all the time. Second, RPis provide a unique feature in that they have external low-level hardware interfaces for embedded systems use, such as I2 C, SPI, UART, and GPIO. This is very useful to electrical engineers (like myself) requiring testing of embedded hardware on a large scale. Third, having user-only access to a cluster (which is the case for most student-accessible systems) is fine if the cluster has all the necessary tools installed. If not however, you must then work with the cluster administrator to get things working. Thus, by building my own cluster I could directly outfit it with anything I might need. Finally, RPis are cheap! The RPi platform has to be one of the cheapest ways to create a cluster of 32 nodes. The cost for an RPi with an 8GB SD card is ~$45. For comparison, each node in one of the clusters available to students here at BSU, was about $1,250. So, for not much more than the price of one PC-based node, I could create a 32 node Raspberry Pi cluster! Update: While the BeagleBone Black was not available when I started this project, I would have chosen it rather than the Raspberry Pi had it been available. It is the same cost once you include an SD card, but it has onboard 2GB of flash storage for the operating system. It also uses a Cortex-A8 ARM processor running at 1GHz. Cluster Performance: I measured basic computing performance in a number of ways (see the paper). MPI performance was measured using HPL (http://www.netlib.org/benchmark/hpl/) with ATLAS (http://www.netlib.org/atlas/). The RPiCluster achieved 10+ GFLOPS peak, with 32-nodes running HPL. The single 3.1GHz Xeon E3-1225 (quad-core) system, I used for comparison, showed about 40 GFLOPS peak (when the HPL problem was optimized for Xeon system). When I run the HPL problem that achieves 10 GFLOPS on the RPiCluster, the Xeon system achieves about 2 GFLOPS. This is because the HPL problem size is so large that it causes paging on the Xeon system. The Xeon system has 8GB of RAM (~6GB usable after OS, etc) whereas the RPiCluster has about 16GB of RAM (~15GB usable after OS, etc).

Just wanted to show off my project I've been playing with over the past few weekends. It's a cluster of Raspberry Pi computers self contained inside of a portable toolbox. Specs: - 15x Raspberry Pi 2s @ stock 900MHz (60 total cores between them) - 15GB RAM (1GB each) - 240GB Flash storage (16GB x 15) - 300W Silverstone SFX power supply (only draws about 45W at the wall under full load) - 120mm exhaust fan - Arduino powered LED strip, because, uh... the 80s. Some benchmarks I ran using a multi-threaded python script I wrote that crunches stock price data stored on an external MySQL database on my network at home. This compares only 1 of the RPi 2 machines to an assortment of desktop PC processors I had laying around. You can essentially divide the RP2 number by 13 to get a rough estimate of cluster performance on this task (divide by 13 and not 15 to account for the networking overhead of 16 machines querying the MySQL database server over a single Gigabit uplink... if the server and cluster were on the same switch you'd get a little better throughput.) All times are in seconds... Lower number = faster run | CPU | 1 Thread | 2 Thread | 4 Thread | 8 Thread | 16 Thread | | AMD Phenom II x4 965 BE | 1807 | 909 | 655 | 564 | 535 | | Intel Core i7 2600K | 1391 | 862 | 639 | 480 | 379 | | Intel Core i7 3770K | 1314 | 661 | 488 | 408 | 350 | | AMD FX-8350 @ 4.4GHz | 1768 | 956 | 677 | 489 | 381 | | Raspbery PI 2 | 16058 | 8176 | 5756 | 4985 | 4688 | | Intel Core i5 3570K | 1327 | 663 | 478 | 406 | 383 | | Inte Core 2 Duo E6400 | 3689 | 2652 | 2594 | 2402 | 2242 |

Windows Server 2012 High Availability series will provide network engineers with the ideas of what technologies Microsoft Server 2012 has to offer in the world of High Availability and the steps to successfully plan, implement, and support High Availability solutions for their managed Windows environment. High Availability Printing, or HA Printing, is the combination of Microsoft Failover Clustering technologies and Hyper-V technologies deployed to make a Windows Server 2012 Print Server highly available. Scale-Out File Server is a feature that is designed to provide scale-out file shares that are continuously available for file-based server application storage. Scale-out file shares provides the ability to share the same folder from multiple nodes of the same cluster. This scenario focuses on how to plan for and deploy Scale-Out File Server A failover cluster is a group of independent computers that work together to increase the availability and scalability of clustered roles (formerly called clustered applications and services). The clustered servers (called nodes) are connected by physical cables and by software. If one or more of the cluster nodes fail, other nodes begin to provide service (a process known as failover). Hyper-V in Windows Server 2012 introduces support for moving virtual machine storage without downtime by making it possible to move the storage while the virtual machine remains running. You can perform this task by using a new wizard in Hyper-V Manager or by using new Hyper-V cmdlets for Windows PowerShell. NLB enhances the availability and scalability of Internet server applications such as those used on web, FTP, firewall, proxy, virtual private network (VPN), and other mission-critical servers. This topic describes the NLB feature and provides links to additional guidance about creating, configuring, and managing NLB clusters. DHCP failover lets you provide a highly available DHCP service without having to configure split scopes or deploy a failover cluster.
