Hardware :: Difference Between Processor And Core?

Dec 22, 2010

When i viewed the cpuinfo file (using command: vi /proc/cpuinfo ), i found that there are listings for 4 processors( i.e 4 sets of listings each one starting with item : processor - 0 ; processor -1 and so on..). Each of them have similar data among which one is "cpu cores" which is 2 for all.. How do i make sense of this data.. 4 processors with 2 cores each ? Also, what could be this hardware be classified as : dual core? quad core ?...

P.s: each of these processor listings also have an item called "siblings" which is 2 for all... Just thought i'll include this here because i felt it may be relevant to this question..

General :: Only One Core Of Dual Core Processor Are Working

Mar 14, 2011

I 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.

Fedora Installation :: 12 Live/KDE: Only One Processor Core Works?

Mar 6, 2010

I wanted to try Fedora 12 Live/KDE on a newly-bought Fujitsu Esprimo P1500. Booting with no kernel options would just freeze the machine. After some random experimentation, I added the option "nolapic" and got a seemingly working machine. However, only seemingly, as it turned out that only one of the processor cores was working (the processor is a "Pentium(R) Dual-Core CPU E5300").

General :: Access CRx Registers On A Multi Core Processor

Sep 9, 2011

I need to set the CR4.MCE bit for all the cores on my system (4). I'd like to write a linux kernel module for that, but I am not sure how to proceed: How do you sequentially access all of the CR4 registers? I have read the Intel manuals and they describe a way to initialize each core, but this is done in the bios.

General :: Difference Between A PentiumM Processor And A P4?

Nov 14, 2010

I have quite an old laptop using an XP OS with an Intel(R)Pentium(R)M processor, 1400MHz 1.40GHz,with 504 MB of RAM,and with Service Pack 3. (this info was taken off the system properties info) I have recently been given a new HD Digital camera which needs a Pentium 4 or above on Windows XP for the software to work. As I said I'm not very good with this sort of thing so have searched for information about the subject, but not had much luck so far understanding the terminoligy used. That's how I came to this website. what the difference is between these two OS, also if my laptop system is compatable with a pentium 4 or not is it more or less that a pentium 4.

Programming :: Perl Child Processes Become Zombie On A Multi-core Processor?

Apr 11, 2011

I have written a simple script which has to find required patterns from a bunch of files ( where each file is around 2 GB each,which contain the output of seq 1 10000000000000) on an 8 core machine.I am current forking 6 child processes which run simultaneously on 6 cores of the processor & have to search for the required pattern in 6 different files & inform the parent process when a pattern is found using a PIPE.

The problem is,when a child process is done reading a text file looking for a pattern,it is becoming a zombie process.It exits cleanly when i put a $SIG{CHLD} = "IGNORE"; in the script.Can any one tell me whats going on & how do i improve the communication between child and parent processes?

Code:
#!/bin/perl
use strict;

OpenSUSE :: Difference Between Core, Community And Playground?

Feb 17, 2010

I've been thinking of going into opensuse for a long time and now with KDE 4.4 is finally out - I'm going to do it. The installation shouldn't be a problem but I wonder how I can upgrade to kde 4.4, since opensuse 11.2 will have 4.3 by default? I saw in the documentation to add these repos:

# Core packages: http://download.opensuse.org/reposit.../openSUSE_11.2
# Community: Index of /repositories/KDE:/KDE4:/Community/openSUSE_11.2_KDE4_Factory_Desktop
# Playground: Index of /repositories/KDE:/KDE4:/Playground/openSUSE_11.2_KDE4_Factory_Desktop

whats the difference between core, community and playground? And isnt there "stable" repos for the KDE 4.4 release? And are there a repo with amarok 2.3 Beta?

Server :: Which Intel Processor To Run A Server On - Xeon Or Core I5

Aug 23, 2010

I would like to run my own server, and I'm thinking of buying a dedicated machine to run it on. I checked out the dell website for a cheap machine to run it on (I don't need high performance - just a personal file server running a few hard drives, and a web/mail server). I noticed that they have some cheap models in their server line that are as cheap as a desktop. Compare:

[URL]

The main difference I see between the desktops and the servers is the use of the Core or Xeon processor, and also, the servers tend to have lower RAM.if I am looking for value, should I opt for a low end desktop or a low end server to run a personal server? Also, what advantage does the Xeon processors and Dell server line have over the desktop models that make it better for running a server?

OpenSUSE :: Get Application To Utilize More Than One Core In Multi-core Setup?

Mar 27, 2011

I 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?

Here is the output of uname -a:Linux linux 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 i686 athlon i386 GNU/LinuxAnd here is the output for one of the cores from cat /proc/cpuinfo:processor : 5

vendor_id : AuthenticAMD
cpu family : 16
model : 10
model name : AMD Phenom(tm) II X6 1100T Processor
stepping : 0

Debian :: Wheezy Only Recognizes 1 Core Or Dual Core CPU?

Sep 7, 2011

I have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. 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.

Fedora Installation :: Upgrading From Core 4 To Core 10?

May 20, 2009

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?
