STXXL : Standard Template Library for Extra Large Data Sets - 4 views

  • The key features of STXXL are:
  • Transparent support of parallel disks. The library provides implementations of basic parallel disk algorithms. STXXL is the only external memory algorithm library supporting parallel disks.
  • The library is able to handle problems of very large size (tested to up to dozens of terabytes).
  • ...4 more annotations...
  • Improved utilization of computer resources. STXXL implementations of external memory algorithms and data structures benefit from overlapping of I/O and computation.
  • Small constant factors in I/O volume. A unique library feature called "pipelining" can save more than half the number of I/Os, by streaming data between algorithmic components, instead of temporarily storing them on disk. A development branch supports asynchronous execution of the algorithmic components, enabling high-level task parallelism.
  • Shorter development times due to well known STL-compatible interfaces for external memory algorithms and data structures.
  • For internal computation, parallel algorithms from the MCSTL or the libstdc++ parallel mode are optionally utilized, making the algorithms inherently benefit from multi-core parallelism.

    « The core of STXXL is an implementation of the C++ standard template library STL for external memory (out-of-core) computations, i. e., STXXL implements containers and algorithms that can process huge volumes of data that only fit on disks. »

Application Request Routing : The Official Microsoft IIS Site - 0 views

  • rules based on the URL, HTTP headers, and server variables to determine the most appropriate Web application server for each request
  • ARR enable hosting providers to route requests from clients to specific Web application servers in a server farm by creating an affinity between the client and server.
  • They can easily add or remove servers from a server farm to match demand throughput without impacting application availability
  • ...5 more annotations...
  • ARR is able to cache on disk any HTTP traffic that passes through the server
  • hierarchy of IIS Web servers running ARR, CDNs and hosting providers are able to considerably reduce the network traffic that traverses up to the origin server.
  • Health monitoring
  • Disk-based caching
  • Warming up cache mode
  •  
    enables Web server administrators, hosting providers, and Content Delivery Networks (CDNs) to increase Web application scalability and reliability through rule-based routing, client and host name affinity, load balancing of HTTP server requests, and distributed disk caching

Installing Windows to a VHD - The Energized Tech - 0 views

  •  
    A walk through of how to install Windows to a virtual hard disk image (VHD) from scratch, instead of a full partition. No VPC was invoked in the making of this post ... just DISKPART a virtual disk into a file, and install.

Rip Blu ray for TV streaming via home media center - YouTube - 0 views

  •  
    MP4 and MKV are the video format we use frequently. Which allow you to store an unlimited number of video, audio, picture or subtitle tracks inside a single file, which obviously make it pretty handy, not to mention an excellent space-saver. Blu-ray to MKV or MP4 will allow you to convert Blu-rays that are ripped straight from a disk, already ripped folders or Blu-rays stored in ISO format. Want to free your Blu-ray player and discs, but retain the HD quality of Blu-ray movies for Blu-ray movie enjoying? This tutorial will show you how to enable Blu-ray movies to MKV/MP4 for streaming to TV via home media center.

TestDisk - CGSecurity - 0 views

  •  
    TestDisk is powerful free data recovery software, designed to help recover lost partitions and/or make non-booting disks bootable again -- particularly when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy!

Clonezilla - 0 views

  •  
    Clonezilla is a PXE network boot used to clone multiple computers at once - much like norton ghost.  Clonezilla Live is a bootable CD/USB image that can replace the need for a network boot server and image host, allowing you to clone a single machine on a local computer without a network.

Joe Duffy's Weblog - OnBeingStateful - 0 views

  • The biggest question left unanswered in my mind is the role state will play in software of the future.
  • The biggest question left unanswered in my mind is the role state will play in software of the future. That seems like an absurd statement, or a naïve one at the very least.  State is everywhere: The values held in memory. Data locally on disk. Data in-flight that is being sent over a network. Data stored in the cloud, including on a database, remote filesystem, etc. Certainly all of these kinds of state will continue to exist far into the future.  Data is king, and is one major factor that will drive the shift to parallel computing.  The question then is how will concurrent programs interact with this state, read and mutate it, and what isolation and synchronization mechanisms are necessary to do so?
  • Many programs have ample gratuitous dependencies, simply because of the habits we’ve grown accustomed to over 30 odd years of imperative programming.  Our education, mental models, books, best-of-breed algorithms, libraries, and languages all push us in this direction.  We like to scribble intermediary state into shared variables because it’s simple to do so and because it maps to our von Neumann model of how the computer works.
  • ...3 more annotations...
  • We need to get rid of these gratuitous dependencies.  Merely papering over them with a transaction—making them “safe”—doesn’t do anything to improve the natural parallelism that a program contains.  It just ensures it doesn’t crash.  Sure, that’s plenty important, but providing programming models and patterns to eliminate the gratuitous dependencies also achieves the goal of not crashing but with the added benefit of actually improving scalability too.  Transactions have worked so well in enabling automatic parallelism in databases because the basic model itself (without transactions) already implies natural isolation among queries.  Transactions break down and scalability suffers for programs that aren’t architected in this way.  We should learn from the experience of the database community in this regard
  • There will always be hidden mutation of shared state inside lower level system components.  These are often called “benevolent side-effects,” thanks to Hoare, and apply to things like lazy initialization and memorization caches.  These will be done by concurrency ninjas who understand locks.  And their effects will be isolated by convention.
  • Even with all of this support, we’d be left with an ecosystem of libraries like the .NET Framework itself which have been built atop a fundamentally mutable and imperative system.  The path forward here is less clear to me, although having the ability to retain a mutable model within pockets of guaranteed isolation certainly makes me think the libraries are salvageable.  Thankfully, the shift will likely be very gradual, and the pieces that pose substantial problems can be rewritten in place incrementally over time.  But we need the fundamental language and type system support first.

  • it analyzes the file system directly and generates a Flash file that you can load locally or remotely on any Flash-supporting web browser. Torta uses Gordon, a library that provides flash generation functionality.

    A very nice graphical front-end for 'du', in Common Lisp. I have tried it - it is trivial to use with SBCL. Version 0.3 works very well on the native Linux filesystem of my laptop, and on its VFAT (Windows) filesystem, provided I mount it with iocharset
