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

stxxl.sourceforge.net C++ STL parallel programming data structures algorithms

berbersunny liked it
  • 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. »

Values, Types, and Operators :: Eloquent JavaScript - 0 views

eloquentjavascript.net/01_values.html javascript programming
shared by fspore on 27 Jun 15 - No Cached
  • Not all operators are symbols. Some are written as words. One example is the typeof operator, which produces a string value naming the type of the value you give it.
  • Having such numbers is useful for storing strings inside a computer because it makes it possible to represent them as a sequence of numbers. When comparing strings, JavaScript goes over them from left to right, comparing the numeric codes of the characters one by one.
  • There is only one value in JavaScript that is not equal to itself, and that is NaN, which stands for “not a number”.
  • ...16 more annotations...
  • In practice, you can usually get by with knowing that of the operators we have seen so far, || has the lowest precedence, then comes &&, then the comparison operators (>, ==, and so on), and then the rest. This order has been chosen such that, in typical expressions like the following one, as few parentheses as possible are necessary:
  • The difference in meaning between undefined and null is an accident of JavaScript’s design, and it doesn’t matter most of the time. In the cases where you actually have to concern yourself with these values, I recommend treating them as interchangeable (more on that in a moment).
  • . Yet in the third expression, + tries string concatenation before numeric addition
  • When something that doesn’t map to a number in an obvious way (such as "five" or undefined) is converted to a number, the value NaN is produced.
  • Further arithmetic operations on NaN keep producing NaN, so if you find yourself getting one of those in an unexpected place, look for accidental type conversions.
  • g ==, the outcome is easy to predict: you should get true when both values are the same, except in the case of NaN.
  • But when the types differ, JavaScript uses a complicated and confusing set of rules to determine what to do. In most cases, it just tries to convert one of the values to the other value’s type. However, when null or undefined occurs on either side of the operator, it produces true only if both sides are one of null or undefined.
  • That last piece of behavior is often useful. When you want to test whether a value has a real value instead of null or undefined, you can simply compare it to null with the == (or !=) operator.
  • The rules for converting strings and numbers to Boolean values state that 0, NaN, and the empty string ("") count as false, while all the other values count as true.
  • where you do not want any automatic type conversions to happen, there are two extra operators: === and !==. The first tests whether a value is precisely equal to the other, and the second tests whether it is not precisely equal. So "" === false is false as expected.
  • The logical operators && and || handle values of different types in a peculiar way. They will convert the value on their left side to Boolean type in order to decide what to do, but depending on the operator and the result of that conversion, they return either the original left-hand value or the right-hand value.
  • The || operator, for example, will return the value to its left when that can be converted to true and will return the value on its right otherwise. This conversion works as you’d expect for Boolean values and should do something analogous for values of other types.
  • This functionality allows the || operator to be used as a way to fall back on a default value. If you give it an expression that might produce an empty value on the left, the value on the right will be used as a replacement in that case.
  • The && operator works similarly, but the other way around. When the value to its left is something that converts to false, it returns that value, and otherwise it returns the value on its right.
  • Another important property of these two operators is that the expression to their right is evaluated only when necessary. In the case of true || X, no matter what X is—even if it’s an expression that does something terrible—the result will be true, and X is never evaluated. The same goes for false && X, which is false and will ignore X. This is called short-circuit evaluation.

Rick Fan and Kevin O'Neill liked it
  • Consequently, it is not reasonable to expect us to make sound business or technical decisions on behalf of the customers, or to resolve conflicting requirements supplied by different end users, or to set priorities for the many requirements that might be collected.
  • We have finally reached the state where if no project champion can be found to see that the right system is built, we cancel the project.
  • The consequence of not explicitly discussing these quality tradeoffs is a surprise upon delivery, when the customer finds that his implicit quality attribute requirements have not been achieved
  • ...3 more annotations...
  • One way to reach an appropriate middle ground in the specification process is to conduct formal inspections of the SRS. A structured document like the IEEE SRS is readily inspected by the design team, the project champions, other representative users, and other software engineers who are not directly involved with the project

      sadly, this is something that is always left to the end to 'clean up'. Meaning, the spec is complete when the project is delivered versus kept up to date and in sync with what we are delivering.
  • A prototype is intended to answer specific questions about functionality or interaction styles. If you don't have any questions, don't bother with a prototype
  • Even in a small software group, a focus on accurately and completely capturing, documenting, and modeling the user requirements is a major contributor to building high quality information systems
