  • 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).

  • Node.js Cluster - Boost Node App Performance & Stability with Clustering

    Get the code here! https://gist.github.com/learncodeacademy/954568155105f4ff3599 Many Node.js developers don't know that Node by default only uses one core of your processor. It's intentional and it's a great move. It just means that you have to run cluster to get the full capacity out of your server. When cluster.js runs, it spins up one copy (fork) of your application for each core on your machine, and balances the traffic between them. It also listens to each fork, so if one dies, it spins up a new one in it's place. Clustering is a great way to add stability to your application and drastically increase it's load capacity.

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). More information: http://coen.boisestate.edu/ece/raspberry-pi/ Update: I finished my PhD Spring 2014. For those interested in further details on what I was doing, an electronic copy of my dissertation is available here: http://scholarworks.boisestate.edu/td/807

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 |

Global data access can greatly expand the reach of your business. Continuent Tungsten multi-site multi-master (MSMM) solutions enable applications to accept write traffic in multiple locations across on-premises and cloud providers. This includes the following important real-world use cases: - Improve performance for globally distributed users registering hardware devices by permitting updates on the geographically closest site. - Ensure availability of credit card processing by spreading transaction processing across two or more sites. Users can still process credit card transactions if a single site is unavailable to them for any reason, including end-user Internet routing problems. - Enable business continuity by using multi-master updates on different hosting providers for service scalability, personalization and software upgrades of GPS devices. Individual Continuent Tungsten clusters already provide excellent single-site database availability and performance. In this webinar-on-demand, we review the benefits of combining multiple Continuent Tungsten clusters into a global multi-site multi-master topology for: - Optimizing your installation for MSMM - Optimizing your application for MSMM - Monitoring and administration - Failover and recovery of individual servers or entire locations.
