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

C++ STL parallel programming data structures algorithms

  • 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. »

software architecture SOA pitfalls

shared by Fabien Cadet on 23 Feb 12 - No Cached
  • The structure seems obvious to system designers who have grown tired of single monolithic systems and want to break those systems up into components and services. What could be more natural than to break the system along the lines of data base managment?
  • Unfortunately this is a huge violation of the Single Responsibility Principle — or its big brother the Common Closure Principle.
  • These principles tell us to group together things that change together, and keep apart things that change for different reasons.
  • ...6 more annotations...
  • When you separate things that change for the same reasons, you have to make changes in many different places in the system.
  • So it’s a lot of work just to get anything working.
  • Moreover, when you group together things that change for different reasons, you expose the components of the system to collateral damage, thrashing, CM collisions, and a whole host of other problems.
  • So what’s the solution? First of all, I question whether the system needed to be partitioned into services.
  • Services are expensive and complicated, you should only create them if you absolutely need to. It’s always easier to live in a single process. Remember Martin Fowler’s first law of distributed objects: Don’t distribute your objects.
  • Many systems could be streamlined, and development made much faster, if the system designers paid more attention to the Single Responsibility Principle.

web development HTTP authentication cryptography

shared by Fabien Cadet on 08 Dec 11 - Cached
  • Fabien Cadet on 08 Dec 11
     
    « A little-known fact about RFC 2617 is that HTTP authentication is extensible. The RFC defines and Apache has modules for Basic and Digest authentication, but developers are free to define different algorithms for use within the HTTP authentication framework, and servers are free to insist that clients support those algorithms if they want access to the server's resources. »
