具學習能力的電腦在電玩中，能開發秘技獲取高分。翻攝YouTube
【簡竹君╱綜合外電報導】人工智慧領域出現重大進展！《自然》期刊前天刊登Google旗下人工智慧公司DeepMind研究，該公司單憑一個具有學習能力的演算法，讓電腦以「類似人類學習模式」自行學會打49種電玩。開發者之一哈薩比斯說：「這是首次有人打造出單一普遍學習系統，（讓電腦）直接從經驗中學習，駕馭各式挑戰。」
哈薩比斯說電腦在嘗試玩「雅達利2600」（Atari 2600）系列遊戲中，電腦對遊戲規則、如何取分一無所知，僅獲得螢幕上的像素和遊戲分數資訊，並被設定要將分數最大化。
看新聞不加蘋果粉絲團對嗎?!
開發取分秘技
電腦在有些遊戲中，經嘗試、記憶犯下的錯誤並修正，有時能自行開發出取分秘技，獲取比真人打機更高的分數；但電腦在有些遊戲便無法學習，只能得低分。
哈薩比斯說人工智慧踏出重要的第一階，能從經驗中學習的電腦，距多功能智慧機器人又更進一步，他希望此類電腦日後能成為人們的「個人助理」。

The Linux IPC (Inter-process communication) facilities provide a method for multiple processes to communicate with one another.
five types of interprocess communication:
n Shared memory permits processes to communicate by simply reading and writing to a specified memory location.
n Mapped memory is similar to shared memory, except that it is associated with a file in the filesystem.
n Pipes permit sequential communication from one process to a related process.
n FIFOs are similar to pipes, except that unrelated processes can communicate because the pipe is given a name in the filesystem.
n Sockets support communication between unrelated processes even on different computers.

Threading Building Blocks (TBB) Math Kernel Library (MKL)
Math Kernel Library (MKL)
The Math Kernel Library is a high-performance, parallel computing math library that includes many useful scientific and engineering functions. Because the key here is performance, vectorization, and multicore, many of these functions deal with large amounts of data. Examples include vectors (as in mathematical vectors) and fast Fourier transforms (FFT). Additionally, several of the libraries within the Math Kernel Library are implementations of standard math libraries, but modified for multicore and vectorized programming.
Threading Building Blocks (TBB)
Threading Building Blocks, or TBB, is a C++ template library that provides a wide array of algorithms and classes to simplify multicore parallel programming.
Conclusion
Composer XE deals with the coding aspect of your parallel development. It consists of the compiler and related libraries. And you can use it without Visual Studio. I often do for short test projects; in such cases, I’ll create a text file with C++ code and just run the compiler itself from the command prompt. With the correct header files and linker options, the compiler will build the code and product an executable – all without Visual Studio.
Note also that Composer is available as a separate product for purchase if you don’t need the additional parts of Parallel Studio. But you’ll most certainly want those other parts. I’ll describe them in the next blog.

Here at Go Parallel, we talk a great deal about parallel programming techniques and, specifically, about Intel Parallel Studio XE. But Parallel Studio is a suite of tools. In this blog, Jeff Cogswell explores one of those tools called Intel Composer XE.
As you continue to learn more about parallel programming, including the difference between vectorization and multicore programming, it’s important to understand where the different tools fit into your programming project. Intel Parallel Studio has several different parts to it. Let’s look at the different parts of Parallel Studio to see how they work together, and when you should use them.
Parallel Studio in Visual Studio
Parallel Studio consists of a set of tools, but when using it with Windows, it’s integrated within Visual Studio. Although technically a separate product, you can easily access the different parts of Parallel Studio from within Visual Studio. In fact, it’s so well-integrated, that from a usability perspective, it feels like you’re just using one product, sort of a supercharged version of Visual Studio. Now let’s look at the different components of Parallel Studio, starting with the first and most important part of suite called Intel Composer XE. Composer XE is itself a suite of products. It consists of the C++ compiler with Cilk Plus extensions, the Fortran compiler, Math Kernel Library, and Threading Building Blocks.

Below are the best performing projects from mid-January through mid-February--together they represent your official ballot for April's Community Choice Project of the Month! The vote takes place mid-February to mid-March.
Vote here for the Community Choice SourceForge Project of the Month for April 2015.
Bodhi Linux: Bodhi is a minimalistic, enlightened Linux desktop. Download Bodhi Linux now.
Task Coach: Task Coach is a free open source to-do manager. It grew out of frustration about other programs not handling composite tasks well. In addition to flexible composite tasks, Task Coach has grown to include prerequisites, prioritizing, effort tracking, category tags, budgets, notes, and many other features. However, users are not forced to use all these features; Task Coach can be as simple or complex as you need it to be. Task Coach is available for Windows, Mac OS X, and GNU/Linux, and there's an iOS app. Download Task Coach now.
CaesarIA (openCaesar3): CaesarIA is an open source remake of Caesar III game released by Impressions Games in 1998, it aims to expand the possibilities of the classical city-building simulators and to add new features showing the city life. Now the game work with Windows, Linux, Mac, Haiku and Android. The original Caesar3 game is needed to play openCaesar3. Download CaesarIA (openCaesar3) now.
