I''ve followed this list for quite a long time and have even posted a couple of times. I used the early versions of IMQ from Devik (I think that was his name), and it worked well. I only ever got the chance to implement it in my test environment. I now need to implement it in my production environment. My Linux core router has nine interfaces and has a 27 megabit connection to the

Hi, all, Does anybody got the most general expression of a unitary matrix? I found one in the book, four entries of the matrix are: (cos\theta) exp(j\alpha); -(sin\theta)exp(j(\alpha-\Omega)); (sin\theta)exp(j(\beta+\Omega)); (cos\theta) exp(j\beta); where "j" is for complex. However, since for any two unitary matrices, their product should also be a unitary matrix. When I

For the llvm LTO example in the link:http://llvm.org/docs/LinkTimeOptimization.html <http://llvm.org/docs/LinkTimeOptimization.html>, I use below build commands to generate three different optimization level binary: -O0, -O1, -O2.

Hi Michael: Sorry to brother. But I''ve been suffered this issue quite a long time. My test environment is 2.6.32.36 + xen 4.0.1 + bnx2, 2.3. Also cpu idle is disabled in grub.

Friends, Thanks for all the feedback. If you have additional success stories or important issues, feel free to continue the discussion. I've learned a lot from your input. As a developer, I spend too much time in the bug tracker, working with particular bugs, so I often wonder how on earth anyone can use this buggy platform for anything business-like. It really feels good to get

Hi - im trawling through my config trying to reduce chances of timeouts etc - I use postgres for all the dovecot and exim4 authentication and location of mail directories etc - and found that by eliminating logging (or reducing to almost none) the queries invovled have gone from >500ms to <3ms - Just wondering if I'll get similar performance gains with dovecot (which is set to be verbose

Hi, Some general questions. I want to build a web page with numerical analysis generated by R. I have a few questions: - Can I control the output of a function? For example, if I do: > summary(data[[5]]) Min. 1st Qu. Median Mean 3rd Qu. Max. 0.0 0.0 120.0 193.3 310.0 10290.0 can I control the output to be something like min=0 q1=0.0 q2=120.0 q3=193.3 max=10290.0

Hi Umesh, Thank you for the suggestion. I can use the "Brute force method " to narrow down the LTO wrong instructions here and there, but I still don't know why these wrong instructions are generated, and how to let Clang LTO don't generate those wrong instructions. I suspect the wrong code is caused by some LTO wrong optimization pass, so I hope to disable all optimizations in

I ran this with a few folks offline and gathered some good feedbacks that I'd like to share thus revive the discussion. First of all, as illustrated in the reply below, cloud service providers require transparent live migration. Specifically, the main target of our case is to support SR-IOV live migration via kernel upgrade while keeping the userspace of old distros unmodified. If it's

HI, Anytime I try to send emails with actionmailer I get a stack level too deep SystemStackError. There were several other posts related to stack overflows, but none of them invovled actionmailer. I''m using some plugins acts_as_taggable, acts_as_ferret, rails 1.1.4, actionmailer 1.2.3. Here is my full stack trace. Any ideas?

In a follow-up to a previous post a couple weeks back, we've implemented a Samba 3.0.20 (Suse packages on 10.0 - recompiled to include idmap_rid) server to replace the Windows 2000 file server in our Win2003 Active Directory. For the most part things have been going well, but occassionally people will get access denied errors to things that they were accessing just fine minutes before. With
