...t likely be upgraded to Fedora Core 2 in the next month or so. Now with all that said, here is my question. I see that maintenance of IMQ has been passed on a couple of times. I see some people say that IMQ is not stable and should not be put into a production environment. My use of IMQ a year ago invovled only egress qdiscs using HTB and SFQ because the egress qdiscs were much more powerful and better than the ingress qdisc. The only problem that I ever had with IMQ was using the iptables target with both PREROUTING and POSTROUTING. I see Roy has posted that IMQ essentially crashes when doing egre...

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

Yes. Usually the LTO pipeline is a bit different from what you're doing, I'm used to see: $clang -flto -O3 -c main.c -o main.o $clang -flto -O3 -c a.c -o a.o $clang -flto -O3 main.o a.o -o main0 -- Mehdi > > $ clang -O2 -flto main.lib a.lib -o main2...

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 as I could) - esp during connection thx Glenn

...about ABI or API compatibility in the kernel level, as long as their applications don't break. I agree the current bypass solution for SR-IOV live migration requires guest cooperation. Though it doesn't mean guest *userspace* cooperation. As a matter of fact, techinically it shouldn't invovle userspace at all to get SR-IOV migration working. It's the kernel that does the real work. If I understand the goal of this in-kernel approach correctly, it was meant to save userspace from modification or corresponding toolstack support, as those additional 2 interfaces is more a side product...

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

Going for such kind of modeling, virtio-pci and virtio-mmio could be also treated as a subclass of virtio as well, they were all implemented via a dedicated transport driver. > > Where does the vhost-user char dev get invovled in with the v2 series? > Is that included? We're working on the a new version, but for the bus/driver part it should be the same as version 1.

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
