Fedora Hardware :: AMD Phenom Quad Core Using I686 Packages?
Jul 10, 2010I'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.

May 27, 2011I 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
[code]...
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).

Feb 19, 2010In my Open-Suse server I have a script, where makepasswd output(by default it generates similar passwords: cGyTbqpr, tpJ1LA, 33EXdo) is redirected to mkpasswd(which uses DES by default) in order to generate salted hash of this previously generated password. I would like to test the strength of this system. I have a quad core CPU, and if I start John The Ripper like this(I want to use -incremental:all flag):
john -incremental:all passwd
..only one core is utilized at 100%. Is there a possibility to make all four cores to crack this password? Or is this possible only after reprogramming John The Ripper? Or what is the algorithm for generating passwords with with -incremental:all flag? I mean if John generates passwords randomly in brute-force mode, then it's smart to start four different John processes simultaneously because then one of those four will find the password firs
General :: Migrating To 64bit Quad Core System
Mar 11, 2010In 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.
CentOS 5 :: VMware Server Only Detects 1 Of 2 Quad Core CPU?
Jan 22, 2010Sadly, 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 RelatedCentOS 5 Hardware :: No Throttling Scalling Speedstep On Xeon Quad-Core
Jun 30, 2009System 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.

Fedora Hardware :: Processors Are Not Active And There Is No An Obvious Process That Captures Cpu?
Apr 25, 2011I just install fedora 15 (64bit) on my Toshiba Satellite L550 laptop.I realise a problem with my fan. It is ON almost allways (90% of the time my laptop is on).My processors are not active and there is no an obvious process that captures my cpu.I had the same problem on fedora 13 and 14 too. I hoped that they solved it in 15.... but... this was not true . When I run it from inside Windows 7 (from a Virtual Machine) it works fine! I was searching to the internet to find a solution (for days) with no luck!Is it a compatibility problem between my CPU and Linux kernel?The problem is very annoying indeed and prevents me for using fedora as my default OS with or w/o A/C.I must say that the same problem exists in ubuntu 10 too

May 20, 2009I 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?

Red Hat / Fedora :: C++ Application CPU Usage Goes To 800% In A -Quad CPU - In RHEL 64 Bit Kernel
Feb 10, 2010I 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.

Mar 27, 2011I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?

I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.

General :: Only One Core Of Dual Core Processor Are Working
Mar 14, 2011I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.
