IBM Discloses Cell Based Blade Server Board Prototype

IBM Discloses Cell Based Blade Server Board Prototype -- Tech-On!: "The prototype, called the Cell Processor Based Blade Server, measured approximately 23 x 43 cm. Each board featured two Cell processors, two 512 Mb XDR DRAM chips and two South Bridge LSIs. The Cell processors were demonstrated running at 2.4-2.8 GHz. 'We are driving the Cell processors at higher rates in the laboratory,' said the engineer. 'If operated at 3 GHz, Cell's theoretical performance reaches about 200 GFLOPS, which works out to about 400 GFLOPS per board,' he added. IBM plans to release a rack product capable of storing seven of these boards."

eDonkey Introduces Catalogs - An Effort to Decentralize Hash Links

Slyck News - eDonkey Introduces Catalogs - An Effort to Decentralize Hash Links: "Catalogs are simply web pages, whose main function is to provide eDonke2000 hash links. They function almost identically to ShareReactor or any other hash site. The major difference however, is the indexing function is integrated into the eDonkey client and is distributed to anyone who wishes to host a catalog (providing the individual has the bandwidth and processing resources.) Since they are web pages, catalogs are not limited to just eDonkey2000 links - one can publish anything he or she wishes."

Bram Cohen Releases BitTorrent Search Engine

Slyck News - Bram Cohen Releases BitTorrent Search Engine: "It has been a very busy month for the BitTorrent community. First Azureus developed their DHT (Distributed Hash Table) client. Second, the MPAA (Motion Picture Association of America) CEO and President Dan Glickman accused the entire BitTorrent protocol of facilitating the distribution of Star Wars, Episode III. Then, Bram Cohen releases his own DHT client, followed by an announcement he will release a BitTorrent search engine. Surely, this was the end of the saga right?

It seems not. Today, the MPAA, FBI and U.S. Customs announced the siezure and criminal prosecution of EliteTorrents.org. While today's news appeared grim for BitTorrent fans, there appears to be a silver lining.

The much anticipated BitTorrent search engine is now functioning on BitTorrent.com. Although earlier reports indicated it would not be ready for two weeks, it appears to be fully operational.

Unlike traditional search features associated with BitTorrent trackers, the search engine crawls the web for torrent files. Whether a torrent file is indexed by a tracker or not is irrelevant. The search engine is designed to efficiently crawl the web and find torrent files regardless of their location.

It appears the search engine is working reasonably well, considering the amount of traffic is must be receiving at the moment. The search engine is no doubt still in testing phases, so search queries may perform slowly."

Kademlia

Kademlia - Wikipedia, the free encyclopedia: "Kademlia is a P2P overlay protocol designed for decentralized peer to peer computer networks. It specifies the structure of the network, regulates communication between nodes and how the exchange of information has to take place. Kademlia nodes communicate among themselves using the transport protocol UDP (see OSI model). Kademlia nodes store data by implementing a Distributed Hash Table (DHT). Over an existing LAN/WAN (like the Internet) a new, virtual network, is created in which each network node is identified by a number ('Node ID'). This number serves not only as its identification, but the Kademlia algorithm uses it for further purposes.

A node that would like to join the net must first go through a bootstrap process. In this phase, the node needs to know the IP address of another node (obtained from the user, or from a stored list) that is already participating in the Kademlia network. If the bootstrapping node has not yet participated in the network, it computes a random ID number that is not already assigned to any other node. It uses this ID until leaving the network.

The Kademlia algorithm is based on the calculation of the 'distance' between two nodes. This distance is computed as the exclusive or of the two node IDs, taking the result as an integer number.

This 'distance' does not have anything to do with geographical conditions, but designates the distance within the ID range. Thus it can and does happen that, for example, a node from Germany and one from Australia are 'neighbours'.

Information within Kademlia is stored in so called 'values', every value being attached to a 'key'.

When searching for some key, the algorithm explores the network in several steps, each step approaching closer to the searched-for key, until the contacted node returns the value, or no more closer nodes are found. The number of nodes contacted during the search is only marginally dependent on the size of the network: If the number of participants in the net doubles in number, then a user's node must query only one more node per search, not twice as many.

Further advantages are found particularly in the decentralized structure, which clearly increases the resistance against a denial of service attack. Even if a whole set of nodes are flooded, this will have limited effect on network availability, which will recover itself by knitting the network around these 'holes'."

Samsung Builds Flash Based Disk Drive

BetaNews | Samsung Builds Flash Based Disk Drive: "Samsung says it has developed a way to store up to 16GB of data using Flash memory, a development that could lead to extended battery life for notebook and tablet PCs. Flash memory has a power consumption that is five percent of today's hard disk drive, according to the company.

These solid-state disk (SSD) Flash-based drives will also provide faster access to data, at about two-and-a-half times the speed of current notebook hard drives. In tests, Samsung was able to read data at 57 megabytes per second (MBps) and write at 32MBps."

BitTorrent Creator to Launch Search Engine

BitTorrent Creator to Launch Search Engine: "The program, developed by Cohen in 2001, looks for torrent files _ digital markers that it needs to assemble complete files from multiple bits of data obtained from other computer users.

Locating the torrents, however, requires finding host sites. And while Cohen himself has not been a target of government or the film and music industries' piracy watchdogs, some operators of Web sites hosting tracker files have been forced to shut down.

Users of the BitTorrent search engine should have an easier time finding the torrent files, wherever they are.

'The goal is to get every single torrent on the Internet indexed,' Cohen said."

ฺBallmer: Google might dissapear in the next five years!

Ballmer: Google might dissapear in the next five years! - Softpedia News: "If until now, the number of world wide active computing systems exceeded the 1 billion threshold, by 2008, their number will exceed 2 billions and according to the same “clairvoyant”, this new generation of systems will be totally different from the ones we were accustomed to.

In the first place, it is outlined the need to develop much more efficient tools to search information to accompany the increase of devices used by the user to save information. Considering the universal trend of migration to the digital information, its organizing in a structure which is easy to consult and to administer becomes a priority for software producers.

According to this concept developed by Ballmer, the online search engines represent the key points of the future technology, and the leader in this domain, none other than Google, is destined to perish in less than five years. These predictions belong exclusively to Microsoft’s CEO who sounds a little like Bill Gates making announcing iPod’s death."

BitTorrent - Trackerless

BitTorrent - Trackerless: "As part of our ongoing efforts to make publishing files on the Web painless and disruptively cheap, BitTorrent has released a 'trackerless' version of BitTorrent in a new release.

Suppose you bought a television station, you could broadcast your progamming to everyone in a 50 mile radius. Now suppose the population of your town tripled. How much more does it cost you to broadcast to 3 times as many people? Nothing. The same is not true of the Web. If you own a website and you publish your latest video on it, as popularity increases, so does your bandwidth bill! Sometimes by a lot! However, thanks to BitTorrent the website owner gets almost near-broadcast economics on the web by harnessing the unused upstream bandwidth of his/her users.

In prior versions of BitTorrent, publishing was a 3 step process. You would:


  1. Create a '.torrent' file -- a summary of your file which you can put on your blog or website

  2. Create a 'tracker' for that file on your webserver so that your downloaders can find each other

  3. Create a 'seed' copy of your download so that your first downloader has a place to download from



Many of you have blogs and websites, but dont have the resources to set up a tracker. In the new version, we've created an optional 'trackerless' method of publication. Anyone with a website and an Internet connection can host a BitTorrent download!

While it is called trackerless, in practice it makes every client a lightweight tracker. A clever protocol, based on a Kademlia distributed hash table or 'DHT', allows clients to efficiently store and retrieve contact information for peers in a torrent.

When generating a torrent, you can choose to utilize the trackerless system or a traditional dedicated tracker. A dedicated tracker allows you to collect statistics about downloads and gives you a measure of control over the reliability of downloads. The trackerless system makes no guarantees to reliability but requires no resources of the publisher. The trackerless system is not consulted when downloading a traditionally tracked torrent.

Although still in Beta release, the trackerless version of BitTorrent, and the latest production version are available at http://www.bittorrent.com/"

Cell Architecture Explained: Introduction

Cell Architecture Explained: Introduction: "Cell is a vector processing architecture and this in some way limits it's uses, that said there are a huge number of tasks which can benefit from vector processing and in part 3 I look at them.

The first machine on the market with a Cell processor will steal the performance crown from the PC, probably permanently, but PCs have seen much bigger and better competition in the past and have pushed it aside every time. In part 4 I explain why the PC has always won and why the Cell may have the capacity to finally defeat it.

In part 5 I wrap it up with a conclusion and list of references. If you don't want to read all the details in parts 1 and 2 I give a short overview of the Cell architecture."

Coraid EtherDrive Storage Blades Ethernet Networked Storage

Coraid EtherDrive Storage Blades Ethernet Networked Storage: "EtherDrive storage uses Ethernet connections between the Server and a shared storage array (pool). See diagram on the left.

Multiple Servers can access a common disk storage system eliminating wasted captive storage and greatly simplifying system backup and restoration.

With EtherDrive the storage pool can be expanded easily with simple Ethernet connections. Storage array performance is limited only by the number of disks configured for striping or RAID and the speed of the Ethernet connection at the Server."

zsync

zsync: "zsync is a file transfer program. It allows you to download a file from a remote server, where you have a copy of an older version of the file on your computer already. zsync downloads only the new parts of the file. It uses the same algorithm as rsync. However, where rsync is designed for synchronising data from one computer to another within an organisation, zsync is designed for file distribution, with one file on a server to be distributed to thousands of downloaders. zsync requires no special server software — just a web server to host the files — and imposes no extra load on the server, making it ideal for large scale file distribution."

Slyck clarifies Azureus “decentralized BitTorrent” support

Slyck clarifies Azureus “decentralized BitTorrent” support - The Peer-to-Peer Weblog - p2p.weblogsinc.com _: "Slyck News has a sharp write-up on the recent enhancements to Azureus, previously reported here as “decentralized BitTorrent”. Though the technical details may be a bit over my head, “decentralized BitTorrent” turns out to be a bit of a misnomer. The new Azureus uses DHT (Distributed Hash Table) to keep downloading and even find new peers even when the original web-based tracker goes down, but Azureus developer Olivier stresses that the new DHT layer, which promises to enhance the efficiency of file distribution, operates independently of BitTorrent and that it shouldn’t be compared to decentralized BT projects like eXeem."
