Slackware :: Core 2 Duo Processor Is Both 32 And 64 Bit?

Jan 11, 2010

I've got a few simple questions that have been bugging me for days:

What do we need slack64 for? What are the differences and advantages?

Is it true that EVERY core 2 duo processor is both 32 and 64 bit?

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.

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..

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.

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;

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?

Slackware :: Multiple Jobs On A Multicore Processor?

May 3, 2011

I've got an intel i7 920 CPU. It has 4 cores, but thanks to hyper threading technology each core could run 2 threads so in /proc/cpuinfo it shows "8 processors".

1. what would be the optimal -j flag when compiling programs on my CPU. I've come across -j7. Why 7?

2. Where and what would I put this flag to make it permanent (eg. .bashrc?)?

Slackware :: HD Video Playback On 2nd Gen Core I3 With Vlc?

Jul 17, 2011

I have a weird HD video in wmv and mkf files playback problem. Every HD video i attempt to play using vlc with vaapi hardware acceleration looks like this: My hardware configuration is i3 cpu, and i am using it's integrated HD2000 video card, which has DVI, HDMI and VGA outputs, which all i am using (not at the same time). However, the problem is present in every combination (DVI only. DVI+HDMI. DVI+VGA. DVI+HDMI+VGA).

As for software, I am using stock 32bit Slackware 13.37, with stock 2.37.6 kernel. And for HD video playback I have installed VLC-1.1.10. libva-0.32.0 and MPlayer-20110624 all these packages came from Alien pastures, so they are quality packages And my vlc settings are also stock :/

Slackware :: Multiple Core CPU's And Can Assign Processes To Both Cores, Or Either One

Whenever I monitor my CPU's, it seems only the first is ever utilized, with the second always being at 0%.Does this mean it is not being used, or just not being reported as in use?Is there anything I could do to improve the situation if it is not being used as much as it could be?On Windows, I can assign processes to both cores, or either one. Is there a way to do something similar in Linux?

Slackware :: X Stopped Working - Failed To Activate Core Devices

Nov 18, 2010

Booting up this morning, no problem. But I accidentally let my laptop go into suspend mode, which doesn't work, so I had to force a restart (Suspend mode on my laptop won't allow me to wake it up again). Now, on rebooting, X doesn't work. I usually boot to RL3 then use startx. Now it just flashes the screen then gives me this error -

Code:
(EE) Error compiling keymap (server-0)
(EE) XKB: Couldn't compile keymap
XKB: Failed to compile keymap
Keyboard initialization failed. This could be a missing or incorrect setup of xkeyboard-config.
Fatal server error:
Failed to activate core devices .....
Fatal server error:
Failed to activate core devices.

Please consult the The X.Org Foundation support at [URL] for help. Please also check the log file at "/var/log/Xorg.0.log" for additional information. If I su - to root and then do "init 4", I get to xdm, and I can log in. X then starts, but with no sound, wrong keymaps, launchers not working; all sorts of things wrong. If I startx as root I get a normal desktop. I have tried copying root's xinitrc to /home/spoovy, but makes no difference.

Slackware :: Fatal Server Error: Failed To Activate Core Devices

Sep 22, 2010

I have 3 accounts setup on this machine. One is root, one is my own, and one is for my kids. My account and root work fine, but today when I tried to log my kids on, startx fails (it also fails from runlevel4). I have tried creating new accounts and they fail as well. I'm not sure when the issue started, but it's been less than a week I believe. The consistent error which I receive is

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
