Borg (Star Trek) The Borg have become a symbol in popular culture for any juggernaut against which "resistance is futile". TV Guide named the Borg #4 in their 2013 list of The 60 Nastiest Villains of All Time.[1] A Borg prop on display at the Hollywood Entertainment Museum. "We are the Borg. Your biological and technological distinctiveness will be added to our own. Resistance is futile. " The complete phrase used in Star Trek: First Contact, as performed by Jeff Coopwood[2] is: "We are the Borg. The phrase "Resistance is futile" became prevalent in popular culture from its use in the television show Star Trek: The Next Generation.[4][5][6][7] The Caeliar offer the remaining humans a merging of human and Caeliar, to allow both groups to survive.
The Borg unicomplex, destroyed in the year 2378. Though Borg costumes are all unique, they share several common characteristics. The method of assimilating individual life-forms into the collective has been represented differently over time. Parallel Virtual Machine. Parallel Virtual Machine (PVM) is a software tool for parallel networking of computers. It is designed to allow a network of heterogeneous Unix and/or Windows machines to be used as a single distributed parallel processor. Thus large computational problems can be solved more cost effectively by using the aggregate power and memory of many computers.
The software is very portable; the source code, available free through netlib, has been compiled on everything from laptops to Crays.[2] PVM was a step towards modern trends in distributed processing and grid computing but has, since the mid-1990s, largely been supplanted by the much more successful MPI standard for message passing on parallel machines. PVM is free software, released under both the BSD License and the GNU General Public License. Design[edit] PVM is a software system that enables a collection of heterogeneous computers to be used as a coherent and flexible concurrent computational resource, or a "parallel virtual machine". Nereus V - Developing a Nereus Application. Programming for NereusV is simple if you have a working knowledge of Java. There are two parts for almost any application: A Nereid (mythical daughter of Nereus) is the code you want to run remotely on nereus clients.
There will typically be many hundreds or thousands of these.An application server which supports communication with your Nereids, manages the overall processing tasks and most importantly records the results. The follwing sections are short notes on the development process, and more details can be followed in the Nereus tutorial.
Building a Nereid The Nereus clients download code and resources from the web just like browsers do to instantiate Java applets. Your Nereid code must implement the NereusService interface for the clients to load and start it. Building an Application Server Nereus contains its own webserver technology, including basic dynamic page creation, so there is no need to use other products like Apache/Tomcat to build a server. The JPVM Home Page. Cluster Virtual Machine for Java | Homepage. NOTE: This project is no longer active since 2000! Cluster VM for Java virtualizes the cluster, supporting any pure Java application without requiring that applications be tailored specifically for it.
The aim of Cluster VM for Java is to obtain improved scalability for a class of Java Server Applications (JSA) by distributing the application's work among the cluster's computing resources. The single system image characteristic of Cluster VM for Java stems from its novel object model that separates the application's view of an object (every object is a unique data structure) from its implementation (objects may have consistent replications on different nodes). This enables us to exploit knowledge on the use of individual objects to improve performance (e.g., using object replication to increase locality of access to objects).
As we proceed, we will continue to update this site to contain additional information on the architecture. This project was formerly known as cJVM. Announcing Terracotta - Java clustering & caching without API's - TheServerSide.com. Terracotta is a new VC funded startup with a new and very different approach to clustering and caching. Current industry approaches either offer a new API to learn in order to cache data, or operate behind programming models that can affect application design, such as Jcache or EJB CMP. Terracotta's technology aims to eliminate I/O bottlenecks in Java--both communication between JVM's (by virtually sharing entire graphs of Java objects at the field change level across a set of JVMs), as well as communication to the database (by wrapping the native JDBC driver with a fault-tolerant caching server), offering a transparent clustering solution for Java without proprietary API's. Effectively, Terracotta can make a set of JVM's in a cluster appear as one JVM (even to the database), so a developer could attach an ordinary collection to an ordinary singleton and have it be accessible across a cluster.
Pretty far. How does the data get propagated from server to server?
