Motherboard ECS A55F2- M3

by uc123

Now with FM2

If you remember, the elder brother of ECS-M3 PCplus A55F2 test this time PCplus ever fit in issue 412. Old brother-M3 ECS A55F2 it is ECS A55F-M3 alias minus the number 2 on the naming. At that time, ECS A55F-M3 comes with support for AMD socket FM1 APU with. Now, ECS A55F2-M3 comes with support for the latest generation AMD APU, Trinity, who took FM2 socket.

u6-435-ecsSelain will support newer AMD APU, ECS-M3 A55F2 also added to the display for digital output. ECS A55F-M3 only offer analog outputs in the form of D-Sub 15pin. Digital outputs are added to this is the HDMI.

In terms of main memory slots and expansion slots, micro ATX motherboard is still giving two slots and three slots. Expansion slot is paired ECS PCIExpress 2.0 x16, PCI-Express 2.0 x1, and PCI. Unfortunately, the use of dual slot graphics card, like his brother, will close the slot PCI-Express 2.0 x1 and could complicate the use of a SATA port.

What about the additional facilities? ECS-M3 A55F2 rely more on the facilities offered by the AMD A55 chipset it uses. Therefore, there is no SATA 6Gbps and USB 3.0. Similarly, eSATA and FireWire. Both of these interfaces are not added to the ECS.

For you who like tinkering with computers, this motherboard does provide a number of options for you to adjust the BIOS setup, but there are a number of common options for tweaking is not offered by ECS. There is also no indicator POST process and switch / easy to clear CMOS button on the rear panel. The good, easy way to clear CMOS utilizing the Page Up key on the keyboard still included.

For business solid capacitors, ECS-M3 A55F2 use. Unfortunately, the use of only on the assessed critical. For others, ECS still wearing electrolytic capacitor. Just a reminder, solid capacitors generally considered to have the durability and quality that is better than electrolytic capacitor that is more affordable.

Given that the cost should you spend to redeem, various limitations this is a natural thing. ECS motherboard consign it for you who need a FM2 motherboard affordable and do not need the completeness of all kinds. Good again, ECS still provides a number of distinctive features such as the EZ Charger can recharge your mobile device battery quickly.


OpenMP 4.0 Specifications Released

The OpenMP 4.0 API Specification is released with Significant New Standard Features

The OpenMP 4.0 API supports the programming of accelerators, SIMD programming, and better optimization using thread affinity

The OpenMP Consortium has released OpenMP API 4.0, a major upgrade of the OpenMP API standard language specifications. Besides several major enhancements, this release provides a new mechanism to describe regions of code where data and/or computation should be moved to another computing device.

Bronis R. de Supinski, Chair of the OpenMP Language Committee, stated that “OpenMP 4.0 API is a major advance that adds two new forms of parallelism in the form of device constructs and SIMD constructs. It also includes several significant extensions for the loop-based and task-based forms of parallelism already supported in the OpenMP 3.1 API.

The 4.0 specification is now available on the 

Standard for parallel programming extends its reach

With this release, the OpenMP API specifications, the de-facto standard for parallel programming on shared memory systems, continues to extend its reach beyond pure HPC to include DSPs, real time systems, and accelerators. The OpenMP API aims to provide high-level parallel language support for a wide range of applications, from automotive and aeronautics to biotech, automation, robotics and financial analysis.

New features in the OpenMP 4.0 API include:

· Support for accelerators. The OpenMP 4.0 API specification effort included significant participation by all the major vendors in order to support a wide variety of compute devices. OpenMP API provides mechanisms to describe regions of code where data and/or computation should be moved to another computing device. Several prototypes for the accelerator proposal have already been implemented.

· SIMD constructs to vectorize both serial as well as parallelized loops. With the advent of SIMD units in all major processor chips, portable support for accessing them is essential. OpenMP 4.0 API provides mechanisms to describe when multiple iterations of the loop can be executed concurrently using SIMD instructions and to describe how to create versions of functions that can be invoked across SIMD lanes.

· Error handling. OpenMP 4.0 API defines error handling capabilities to improve the resiliency and stability of OpenMP applications in the presence of system-level, runtime-level, and user-defined errors. Features to abort parallel OpenMP execution cleanly have been defined, based on conditional cancellation and user-defined cancellation points.

· Thread affinity. OpenMP 4.0 API provides mechanisms to define where to execute OpenMP threads. Platform-specific data and algorithm-specific properties are separated, offering a deterministic behavior and simplicity in use. The advantages for the user are better locality, less false sharing and more memory bandwidth.

· Tasking extensions. OpenMP 4.0 API provides several extensions to its task-based parallelism support. Tasks can be grouped to support deep task synchronization and task groups can be aborted to reflect completion of cooperative tasking activities such as search. Task-to-task synchronization is now supported through the specification of task dependency.

· Support for Fortran 2003. The Fortran 2003 standard adds many modern computer language features. Having these features in the specification allows users to parallelize Fortran 2003 compliant programs. This includes interoperability of Fortran and C, which is one of the most popular features in Fortran 2003.

· User-defined reductions. Previously, OpenMP API only supported reductions with base language operators and intrinsic procedures. With OpenMP 4.0 API, user-defined reductions are now also supported.

· Sequentially consistent atomics. A clause has been added to allow a programmer to enforce sequential consistency when a specific storage


Hunger Games themed semi-iterated prisoner’s dilemma tournament

by uc123

With all the talk surrounding it, crowdsourcing science might seem like a new concept and it might be true for citizen science efforts, but it is definitely an old trick to source your research to other researchers. In fact, evolutionary game theory was born (or at least popularized) by one such crowdsourcing exercise; in 1980, Robert Axelrod wanted to find out the best strategy for iterated prisoner’s dilemma and reached out to prominent researchers for strategy submissions to around-robin tournmanet. Tit-for-tat was the winning strategy, but the real victor was Axelrod. His 1981 paper with Hamilton analyzing the result went on to become a standard reference in applications of game theory to social questions (at least outside of economics), agent-based modeling, and — of course — evolutionary game theory. Of Axelrod’s sizeable 47,222 (at time of writing) citations, almost half (23,370) come from this single paper. The tradition of tournaments continues among researchers, I’ve even discussed an imitation tournament on imitation previously.

The cynical moral of the tale: if you want to be noticed then run a game theory tournament. The folks at Brilliant.org— a website offering weekly olympiad-style challange problems in math and physics — took this message to heart, coupled it to the tried-and-true marketing technique of linking to a popular movie/book franchise, and decided to run a Hunger Games themed semi-iterated Prisoner’s dillema tournament. Submit a quick explanation of your strategy and Python script to play the game, and you could be one of the 5 winners of the $1,000 grand prize. Hooray! The submission deadline is August 18th, 2013 and all you need is a Brilliant account and it seems that these are free. If you are a reader of TheEGG blog then I recommend submitting a strategy, and discussing it in the comments (either before or after the deadline); I am interested to see what you come up with.

I will present the rules in m


Cool, Indonesian People Make “Printer” 3D

by uc123

Starting from his love for the graphic design world, John Djauhari now assembling machines printer (printer) 3D. By leveraging open source technology, 3D printers that can print documents assembled Johanes digital into three-dimensional objects.

John worked as a product designer. Some clients who want to make a product sometimes is not satisfied if only to see the design in the form of digital documents. They want physical shape despite the small size.

“Well, from there, why do not I make a 3D printer itself,” he said when met at the show Popcon KompasTekno Asia 2013 in Jakarta Convention Center, beginning last July.

John also likes the toys (toys). Many colleagues who designed character toys and wanted to realize his ideas into tangible form. Some of them use the services of John for 3D printing.

Keseriusan Johanes merakit printer 3D dimulai pada 2011. Ia mendirikan Bikin Bikin 3D Print dan aktif ikut pameran untuk memperkenalkan teknologi ini. Kala itu, desain luar printer buatannya masih berupa kerangka. Setelah melewati beberapa kali pengembangan, kini printer 3D-nya semakin akurat dan didesain menggunakan casing. “Akurasinya sampai 0,2 mm,” tutur Johanes.

Akurasi itu dibuktikan dengan mencetak replika arca yang penuh detail dan lekukan. Johanes terlebih dahulu memindai seluruh bagian arca asli yang tersimpan di Museum Nasional. Setelah mendapat filepindainya, mulailah Johanes mendesain 3D lalu mencetak dengan printer buatannya sendiri.

Memanfaatkan “open source

Dalam mengembangkan printer 3D, Johanes memanfaatkan teknologi open source untuk driver dansoftware. Ia ikut dalam forum internet yang khusus membahas teknologi printer 3D.

“Di forum ini, kita bisa tahu kalau ada algoritma yang lebih baik dan memberi struktur lebih mudah. Bukan cuma soal teknis, dari sana juga kita tahu soal materi yang mudah dicari dan lebih terjangkau,” jelasnya.

Untuk mendesain bentuk 3D, Johanes menggunakan software Pronter Face dan Repetier. Komputer yang dipakainya terhubung ke motherboard printer melalui kabel USB. Motherboard inilah yang memerintahkan gerakan koordinat X, Y, dan Z, menerjemahkan dokumen digital menjadi obyek nyata 3D.

Printer 3D yang dibuat Johanes masuk dalam tahap pengembangan akhir. Ia membuka pre-orderdengan harga Rp 10 juta. Setelah masa pre-order berakhir pada September 2013, printer 3D bakal dibanderol Rp 12 juta.


Provide Application Blackberry Pay Zakat
