Xen on Intel i7 Nehalem?
Hello,
i´ve got a new Intel Nehalem server with an i7-920 CPU.
I installed a Debian Lenny OS ...
Now, i cannot find any images for hypervisor or kernel that seem to be runable on that hardware.
:-O
All of that is AMD:
apt-cache search hypervisor

Number of worker processes on hyperthreaded processor
Good morning,
The tuning page says worker_processes should be at least the number of CPU cores on a dedicated server. In the case of hyper-threading, should this be the number of cores or the number of threads?
For example the Intel Core i7-2600 Quadcore[1] has 4 cores and 8 threads. Would I start my worker_processes at 4 or 8?
Finally, would the same apply to Nginx worker processes?

Intel Mobo MARVEL RAID adapters and amd64 FreeBSD on QuadCore and i7 series Processors
These show up under Windows XP as if they are SCSI adapters (they're
not, obviously.)
Has there been any view towards supporting these on FreeBSD? They're on
all the recent Intel motherboards for the last year and a half or so.
Also, is there any particular benefit (or penalty) to running the amd64
build on Quad-Core or i7-series processors? I have an app that might
benefit from

rails hyperthreading on Quad core
Hi, my video sharing website (politube.org) that I developed with rails,
runs on lighttpd/fcgi (I know it is obsolete by now) and is severely
under load and regularly blocks because the lighttpd process chews up
50% of RAM (1GB).
So now I want to move the system to a new server with 8GB, 64bit ,
Quad core processor (intel i7 920) but I am not sure if hyperthreading
will really do anything better.

Use of processor by R 32bit on a 64bit machine
Dear all,
I've recently purchased a new 64bit system with an intel i7 quadcore
processor. As I understood (maybe wrongly) that to date the 32bit
version of R is more stable than the 64bit, I installed the 32bit
version and am happily using it ever since. Now I'm running a whole
lot of models, which goes smoothly, and I thought out of curiosity to
check how much processor I'm using. I

Nehalem & Digium Wildcard issues?
Just putting this out there to see if anyone else has seen any issues.
May cross-post to asterisk-dev if it's indeed a bug (and not my own
stupidity).
I've got a Digium TE220 (2xT1 interface w/Echo canceller) that in two
separate Nehalem-based (Xeon E5520 "Gainestown") boxes (HP ProLiant
ML350 G6; HP Z800 Workstation) has caused numerous kernel panics. This

[LLVMdev] How does SSEDomainFix work?
Hello. This is my 1st post.
I have tried SSE execution domain fixup pass.
But I am not able to see any improvements.
I expect for the example below to use MOVDQA, PAND &c.
(On nehalem, ANDPS is extremely slower than PAND)
Please tell me if something would be wrong for me.
Thank you.

Did you actually measure runtime, or did you look at assembly?

[RFC] Implement Batched (group) ticket lock
In virtualized environment there are mainly three problems
related to spinlocks that affect performance.
1. LHP (lock holder preemption)
2. Lock Waiter Preemption (LWP)
3. Starvation/fairness
Though ticketlocks solve the fairness problem, it worsens LWP, LHP problems.
pv-ticketlocks tried to address this. But we can further improve at the
cost of relaxed fairness.

Confindence interval for Levenberg-Marquardt fit
Dear all,
I would like to use the Levenberg-Marquardt algorithm for non-linear
least-squares regression using function nls.lm. Can anybody help me to
find a a way to compute confidence intervals on the fitted
parameters as it is possible for nls (using confint.nls, which does not
work for nls.lm)?
Thank you for your help

460 GTX performance on SC 2
Hello,
I'm trying to play SC2 with the following setup, and it's only playable with the lowest settings. I think I've already put in most of the tweaks that people typically point to.
Can I get advice on how I can get reasonable fps for higher settings?
Here's my setup:
GTX 460 1GB

Levenberg-Marquardt algorithm
Hi All,
Is the Levenberg-Marquardt algorithm available in R. This method combines the
steepest descent algorithm and Newton's method.

2.6.31 xenified kernel - not ready for production
Hi,
I just want to know if somebody use 2.6.31.4 xenified kernel (aka
OpenSUSE) in production?
We have been testing it on new Nehalem Xeon server for few weeks w/o
any problem.
But as soon we tried it on production machine - after several
production domUs started - hard OS failure.
We had to switch back to 2.6.18.8 - xen stock kernel.

Intel i7-940, DX58S0 motherboard, Radeon X1950 Pro video card
This computer is my main desktop machine --- an Intel i7-940 CPU and DX58S0
motherboard with a Radeon X1950 Pro video card. It's currently running Fedora 11
and working just fine.
However, I have been slowly moving all of my "computer stuff" off of Fedora
and onto Centos, and this (and my Acer Aspire One laptop) are the only Fedora
installations that I now have left.

Centos 6 installation problem on i7 machine
I want to confirm that the solution posed by Ren? re installing kmod-fglrx from elRepo also works well for HP Proliant servers (in my case DL360 G6) with ATI gfx to restore the text boot progress display and virtual terminals.? Kudos for ending a long and maddening search for a fix.
