I'm having an interesting problem. I have an AMD quad core and for some reason I can't install x86_64 packages only i686 it originally didn't bother me, but now that i've finally decided to install an ATI graphics card I bought off a friend before i was running fedora but i can't installthe driver for it.

I installed Fedora 15 on my relatively new Laptop machine and stumbled upon an odd thing:Even though my CPU is an Intel i7-640M dual core (2x 2.8 Ghz) it somehow seems to be recognized as a quad. System monitor shows 4 CPUs (all of the used to some extend) and even "cat /proc/cpuinfo" gives me 4 processors:
Code:
processor: 0
vendor_id: GenuineIntel
cpu family: 6

At the same time the system (while relatively stable) is incredibly slow when it comes to complicated calculations (I do neuron simulations on a custom C++ framework).

I have installed OpenSuse 11.3 32 Bit in a virtual machine on an older computer on a Windows XP host and on a new computer with AMD Phenom II X4 965 processor.
With sysbench I tested the performance of mutex and on the new computer it is 3 - 4 times slower than on the virtual machine. Other performance tests with sysbench for CPU, memory and threads are faster on new computer like expected. I tested this, because I have a slower performance of table creation in MySql tested with sql-bench, where creation of 10000 tables lasts 45 seconds on the virtual machine but over 400 seconds on the new computer.
I have tested with kernel-desktop and kernel-default but there are not large differences. File creation was tested with bonnie++ and is on newer computer faster as expected.
My questions are:
- Why is the mutex handling on the multi core CPU slower than in the virtual machine and how to speed up this?
- Or is there another reason why table creation of MySql is so much slower on multi core CPU?
In the past, I've deployed new 64 bit systems and I've worked on and developed on 64 bit systems. But until a week ago, my workstation was a 32 bit system. Now, it is a 64 bit quad core Phenom II system, and I suppose I need to start the migration to 64 bit Linux. I do not want to blow off my system and rebuild it. This particular system dates back a decade and through many many updates. There is some digital debris in it, but there is also a fair amount of customization that I have implemented either for my own purposes or for customers, and to lose that customization would represent a headache for me.
What I want to do is install a 64 bit system over top of the 32 bit system. It is my hope that doing this would install the necessary 64 bit libraries, while not impacting the existing 32 bit libraries (except with some possible symlink problems). I then, hopefully, could boot into a 64 bit kernel while still running 32 bit programs. Is this feasible? My backup system is comprehensive; I COULD just try it and back up if my system became hosed. But I'd rather not; I have a lot of work to do and I'd rather not learn by doing in this case.
Sadly, I google'd the heck out of this and even the vmware community has no answers. So, I decided to turn to the experts and see if you can provide a better solution than [URL]. The system sees both CPU's and all of the cores (cat /proc/cpuinfo). I have tried with HT and without HT (I never run HT anymore; seems to hurt performance in my workloads). I've tried the recent and newest kernels for CentOS 5.4 and still have no luck. There seems to be lots of people having this issue, but no real solutions.

View 2 Replies View RelatedSystem recognizes that CPU is capable of throttling, but there is no module to govern it. So Xeon always runs at full frequency.This is not convenient as my server is not always in full use, so I would like it to lower power consumption, especially for AC, with frequency scaling enabled.Can you help me is this some bug, misconfiguration in default kernel or guys who writes kernel think that scaling is not necessary for servers processors?
From my analysis so far, I think that the issue lies with the fact that module acpi-cpufreq does not support Xeons and that there is no dedicated module for this processor family (e.g. p4-clockmod) module in the default kernel.

I am/was(?) running a dual boot Windows 7 Home Premium and Fedora 12 system on an AMD Phenom platform.
I thought that I would try the KDE desktop and installed it with the command
yum groupinstall "KDE (K Desktop Environment)"
After tasting KDE for a while I decided that I far prefer Gnome.
I removed the KDE with
yum groupremove "KDE (K Desktop Environment)"
This appeared to work but I then found that whilst I can boot into Windows 7, I can no longer boot into Fedora 12.
I have tried booting the F12 DVD and going into to the Rescue function. I re-installed grub but still cannot boot into F12.
I have looked at grub.conf but can see nothing wrong.

I have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?

I am facing an high CPU Usage 800% in a(Quad CPU, RHEL 64 bit kernel) with my C++ application .
The details are below:
1)The C++ Application has been compiled in RHEL (2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux)32 bit server(Quad CPU 8 cpu) in Dev lab. When this application has been tested for 12 hrs in the Dev lab, the CPU usage is varying between 20% to 50% .
However, when the above C++ application deployed in production which is RHEL (2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:56:44 EST 2007 x86_64 x86_64 x86_64 GNU/Linux)64 bit server the CPU usage is found to be increasing constantly to 800%.
2)When the CPU reached to 800% in Production Server, we have taken the pstack of the C++ Application process by using the command pstack p [captured thread id ] and we found that the pstack is showing the high CPU
usage (800%) in below libraries:
If there is any GLIB /pthread library/any other differences between 32 bit and 64 bit kernel. Since the application has been compiled in a 32 bit kernel and deployed in 64 bit kernel. Please provide your support on the same.
I am in school for my CIS degree and the book I am using this session covers Windows XP and Fedora Core 4. I am having trouble finding & downloading Fedora Core 4.

Nothing extreme, no gaming, just whatever I can get with good stability with the stock heatsink and fan.I was going to get 8GB on 2x4GB strips but they are all CAS latency 9. The MB has 4 slots for a total of 16GB capacity. Would I be better off going with 4x2GB strips and try to get a lower latency strip like maybe 7?
