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. »

Fabulous Adventures In Coding : The Stack Is An Implementation Detail, Part One - 0 views

  • Almost every article I see that describes the difference between value types and reference types explains in (frequently incorrect) detail about what “the stack” is and how the major difference between value types and reference types is that value types go on the stack.
  • I find this characterization of a value type based on its implementation details rather than its observable characteristics to be both confusing and unfortunate. Surely the most relevant fact about value types is not the implementation detail of how they are allocated, but rather the by-design semantic meaning of “value type”, namely that they are always copied “by value”.
  • Of course, the simplistic statement I described is not even true. As the MSDN documentation correctly notes, value types are allocated on the stack sometimes. For example, the memory for an integer field in a class type is part of the class instance’s memory, which is allocated on the heap.
  • ...3 more annotations...
  • As long as the implementation maintains the semantics guaranteed by the specification, it can choose any strategy it likes for generating efficient code
  • That Windows typically does so, and that this one-meg array is an efficient place to store small amounts of short-lived data is great, but it’s not a requirement that an operating system provide such a structure, or that the jitter use it. The jitter could choose to put every local “on the heap” and live with the performance cost of doing so, as long as the value type semantics were maintained
  • I would only be making that choice if profiling data showed that there was a large, real-world-customer-impacting performance problem directly mitigated by using value types. Absent such data, I’d always make the choice of value type vs reference type based on whether the type is semantically representing a value or semantically a reference to something.

Security, security! But do you test it? - 0 views

  •  
    There is no fragment in program code where you cannot make mistakes. You may actually make them in very simple fragments. While programmers have worked out the habit of testing algorithms, data exchange mechanisms and interfaces, it's much worse concerning security testing. It is often implemented on the leftover principle. A programmer is thinking: "I just write a couple of lines now, and everything will be ok. And I don't even need to test it. The code is too simple to make a mistake there!". That's not right. Since you're working on security and writing some code for this purpose, test it as carefully!

book: Exercises in programming styles, by Chritina Videira Lopes - 10 views

  •  
    "In the 1940s, the French writer Raymond Queneau wrote a jewel of a book called Exercises in Style, featuring 99 renditions of the exact same story, each written in a different style. The story being fairly trivial and always the same, the book highlights form, rather than content; it illustrates how the decisions we make in telling a story affect the perception of that story. Inspired by Queneau, I decided to embark on the project of writing the exact same computational task in as many styles as I have come across over the years. Exercises in Programming Style (#EPSBook) features 33 renditions of a simple computational task -- counting the frequency of words in a given file. All renditions are written in Python. This book is a companion text for code that is publicly available in Github. Software developers with many years of experience may enjoy revisiting familiar programming styles in the broad context of this book and learning about styles that may not be part of their normal repertoire. This book can be used as a textbook for advanced programming courses in Computer Science and Software Engineering programs. Additional teaching materials, such as lecture slides and implementations of each style in other languages, are also available."

Traits: The else-if-then of Types, by Andrei Alexandrescu - 3 views

  • Definition: A traits template is a template class, possibly explicitly specialized, that provides a uniform symbolic interface over a coherent set of design choices that vary from one type to another.
  • An important use of traits is as "interface glue"—universal non-intrusive adapters. If various classes implement a given concept in slightly different ways, traits can fit those implementations to a common interface.
  • Definition: A traits class (as opposed to a traits template) is either an instantiation of a traits template, or a separate class that exposes the same interface as a traits template instantiation.
  • ...3 more annotations...
  • traits with state
  • general-purpose traits
  • hierarchy-wide traits—traits that you can define in one shot not just for a class, but for a whole hierarchy or subhierarchy.

The Ideal HPC Programming Language - ACM Queue - 2 views

  •  
    What if programming did not mean having to learn a language someone else devised and then wrestling with the limitations of that language, its compilers, and computers to implement your task? What if it meant, in a sense, the opposite? You could write your program in whatever way was most expressive for you, without regard for language rules imposed by someone else. Then it would be somebody else's job to define the programming language that would make sense of what you wrote, write the compilers to digest the program, and build the computers that would efficiently run the task you specified.

Using RabbitMQ with C# and .NET - 3 views

  • I'm currently working on a project where I need to be able to transfer a large number of requests via JSON over web services. I need to take some of that data, do some aggregation with it, and store it in a persistent store. In order to allow the data to be reliably processed in a number of different ways, I wanted to place the incoming data into multiple queues and have it processed and then stored.
  • RabbitMQ fits the bill on all of these fronts, is crazy easy to setup and use, and is very fast.
  • RabbitMQ is written in Erlang
  •  
    RabbitMQ is a cross-platform implementation of an Advanced Message Qeuing Protocol (AMQP) broker (similar to MSMQ). There's a .Net client, and it allows you to decouple your routing and an message storage, and do so in a cross-platform way.
