Inside Japan’s Future Exascale ARM Supercomputer
The rumors that supercomputer maker Fujitsu would be dropping the Sparc architecture and moving to ARM cores for its next generation of supercomputers have been going around since last fall, and at the International Supercomputing Conference in Frankfurt, Germany this week, officials at the server maker and RIKEN, the research and development arm of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) that currently houses the mighty K supercomputer, confirmed that this is indeed true.
Fujitsu turns to ARM for Post-K supercomputer
Alternative chip architectures are taking some thunder away from Intel's x86 at this week's International Supercomputing Conference in Frankfurt.
China's TaihuLight, which was ranked the world's fastest supercomputer, has a homegrown chip. And the ARM architecture, which dominates mobile-device chips, will appear in Fujitsu's next flagship supercomputer.
Intel: ARM Servers To Renew Their Attack
Up until now, server chips based on ARM Holdings' (NASDAQ:ARMH) architecture have had little impact on the data center market, and Intel's (NASDAQ:INTC) Data Center Group has continued to grow. ARM server vendors are preparing the next wave of server chips based on 14-16 nm FinFET technology. These will be much more competitive and energy efficient and could start to erode Intel's share of the data center by 2017.
I'm new to enhanced security and I'm considering SELinux..
I've a question about SE. Is really needed? I see that most distro does not support it, and when supported, user (in most cases) disable it on server and desktop. On a great number of ml I can read "oh, I have a problem" and reply "oh, disable selinux"
Why users suggest to disable it instead to study it?
Do you got some experiences with it and if yes, selinux made the differences?

I have just joined a Computer lab as a PHD candidate. I have used debian based linux system in past. I have started to use RHEL based linux system here. They are mostly single quad core system with graphic cards running centos 6.
Yesterday I spent most of time untangling the wire mess around all these GPU system like Dell Precision T7500, Fujitsu Celsius. It is not my job to look after hardwares but I thought somebody must do the minimum.
Now coming to the problem, I plugged a fujitsu power cable (last cable that I had plugged) into a wall socket and it started sparking. I initially hoped that it will be gone soon, but two connected GPU system (which is most likely referred as server) in opposite corner of room started beeping while the sparking continued.
I immediately switched off the wall socket and pulled out the Fujitsu power cable. The Server system kept on beeping for some time. Not sure about what I should do, I switched off the Server wall socket too. After sometime I plugged the Fujitsu cable in other available wall socket and checked all the other GPUs which uses same power line. All of these GPUs are working fine, even that one GPU which is connected to same extension board as the server machine.
I next checked what does beeping and red led light represents. The server system is a combination of two Supermicro GPUs, totalling upto 16 core and 64 GB of RAM. It also have at-least 4 Graphic Cards. I studied the Beep Code manual and realized that I may have caused some fatal error in that machine.
I tried to boot the server system today to check the number of beeps it is giving. The beep was very long without any pause. The fan was super noisy too. However, all this happened to only one of those two connected GPUs. The other GPU was green lit and also was not making any noise. I have switched the power off again.
I have to inform all about this on Monday. I may have to brief the maintenance guy as the system is still under warranty.
Please provide me some of your experienced insight into my problem.submitted by /u/Z3Hexenal
My father often feels unhappy with his current computer setup using Windows. However, attempts to get him to try Linux have so far failed. The most important reason for him to stick with Windows, is that he writes documents in Word for his work, and that he wants to be sure that these documents have the same formatting when his colleagues read them.
I expect that interoptability of rich text documents is a problem that many of you frequent Linux users face day-to-day, so maybe you can shine some light on this concern of his. I myself work in a programmers-environment where most of us use Linux, so I don't deal with this problem very often.
Is the compatibility between documents written on Linux (OpenOffice, LibreOffice) and Microsoft Word a sound concern?
I seem to remember that the formatting of Word documents drastically changed between versions (e.g. a document witten in Word 2010 will look very different in Word 2007, again different in Word 2003, etc.) but I was unable to find hard proof of this.
I know that OpenOffice/LibreOffice are able to both read and save .odt and .doc(x) formats, and Microsoft Word is able to do the same.
So, my questions:
- Do documents written with LibreOffice/OpenOffice drastically change formatting when opened in Microsoft Word?
- How is this vice-versa?
- Is it better to use .odt or .doc(x)to save the files, if you want to be sure that the files look the most alike between programs (/program versions)?
Can someone tell me what should I do to fix on "this must be done before squid can run"?this is my problem: http://i.stack.imgur.com/61pnP.png; http://i.stack.imgur.com/NnQjH.png. that right, the error call FATAL. for more detail, I like you visit my /etc/squid3/squid,conf file on: pastebin.com/j55bbUE. Can someone explain how to fix it? or just edit free for me.submitted by /u/jamesfinalreturn
