DragonFly BSD one main developer Matthew Dillon just announced AMD confirms a CPU bug that he found there. Matt referenced in the notice in the mail to and from content-the problem is a part of continuous annealing code stack then do (nearly) returned under the instructions of, the processor causes the stack pointer to point to an error value. This Bug in the DragonFly BSD is system specific performance under large load of random error.

In messages and Dillon, AMD said company engineers provide code samples and has received his careful analysis has appeared in DragonFly BSD system code in the fill_sons_in_loop () function error, and confirm that the error was caused by defects in some AMD processors; Provide fill_sons_in_loop code exists in the compiled version of a very special kind of continuous annealing stack and returns, will lead to a defective CPU stack pointer is assigned the wrong value.

Article does not mention a defect exists in all of the specific CPU model. But according to research reports provided by Dillon, one of four Opteron 6,168 and two Phenom II X4 820 machines exist on the issues, which is used to compare the Xeon E3 is no problem.

AMD company confirms that a few days ago was completed on the server company SeaMicro’s takeover. This deal at a cost of $ 334 million, of which us $ 293 million cash transaction. This plan has announced on March 1 of this year, AMD expects the acquisition enhanced their strength in low-power server market. At the same time, AMD believes that this deal will get out of cloud data center plays a critical role in the process.

Low-power service has become a commonly used way of processing operations and Web applications in the cloud. Large-scale network platforms, such as Facebook and Google, already a long time ago started exploration through the use of streamlined, low-power systems to enable data center transformation. Recent ARM has released a specially designed for this type of server using the design of low-power processors, helped push the development of low-power server market.

After the deal is completed, SeaMicro may be named AMD company data center server solutions.

AMD Neal Robison, head of content and program support in an interview a few days ago about his views on the current operating system of the mobile device and the PC. Neal Robison said investments Intel MeeGo or HP’s WebOS now meaningless. Device operating system Division now has a very mature, including Google Android, Apple’s iOS, and Microsoft Windows.

Neal Robison believes that it has been able to meet all three operating systems and user needs. If invest in it other than the three major operating systems operating system, investment will not be output, including Tizen operating system for Intel and Samsung Electronics Research and development cooperation.

After the failure of the Intel MeeGo operating system, Intel and Korea Samsung Electronics Tizen jointly preparing to launch cross-platform operating systems. Tizen also apply to devices such as Smartphones, tablets and netbooks. Allegedly, Tizen combines the strengths of the Limo and Linux operating systems, and Webb development environment built on HTML5 and WAC standard, cross-platform applications developed for the devices.

Neal Robison, AMD and Intel will be taken different paths, focusing on product research and development for the market success of the operating system has been made.
