Compiling a kernel on this machine first time and get upset with which processor family/type/options to select for my Intel Pentim Dual Core T2390.Does sombody know how to configure kernel better for this processor?

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.

I also downloaded the same version for i386 processors and tried to install the OS for my HCL Pentium Dual Core T4300 @2.1Ghz 4GB RAM laptop, details of which are given in the following two screenshots: dscf0105.jpg and dscf0106.jpg I already have Debian Lenny 5.0.4 installed on the laptop dscf0104.jpg and the laptop works fine when I run the Debian OS or Knoppix liveCD image stored in the HDD of the laptop. We all know that the Ubuntu LTS live CD leads to the following option: Screenshot.jpg However, in my laptop the operation freezes before we can reach the above option. The screenshot explains the situation: dscf0107.jpg I know I could always use one of the alternate downloads and install the OS from it. But my point of contention is: where is the matter going wrong? Can't we use the graphical installer CD to do a CUI installation?

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.

View 3 Replies View RelatedWhen 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..
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.

View 3 Replies View RelatedI have been looking at things with the uname command and was wondering if you can install a system with 64/32 bit when it was actually not the one you installed (e.g. you install a 64 bit OS on a 32 bit comp). I was basically wondering how to tell what type of hardware I actually have instead of what the Debian package installed. (In order to ensure that I am running the hardware the way it was designed.) At the moment, I am looking at my processor (uname -p returns "unknown") and the machine build (uname -m returns i686).
View 3 Replies View RelatedI 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").

View 7 Replies View RelatedI 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?

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?
Not sure if this is where this belongs, but I figure someone will at least point me in the right direction...So, I have an old MSI 694d Pro board, with 2 PIII 800's on it. So, I know it will support up to two Gigs of RAM, which is cool, and up to 933Mhz cpus..I know if it was a single processor board, the difference would be negligible, BUT, would I see any kind of difference if I found 2 933s and stuck them on. (Once you move into dual processors, I kind of get lost in the math...lol)
I think I could pick up some older PIIIs for pretty cheap. But would even $5 be a waste of money?Also, if anyone else has this board, I'm having networking issues. Ubuntu knows there is a PCI network card attatched, (And i've tried 3 different cards) but it will NOT connect. Would there be a board setting that would prevent network connections?
I consider building a new computer using a mainboard with support for two processors. I wish to do this to improve performance of course, specifically in regards to audio production. Though, what I would like to know is if anyone has some experience with using such a hardware on an ordinary desktop system and if there are some general implications I should be aware of?
