Hardware :: Detecting Correct Machine Type / Processor

Jun 4, 2010

I 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).

Red Hat / Fedora :: How To Get Processor Type At Particular Root

Jun 16, 2010

How do I get arch/processor type at a particular root? On Solaris, I can get it by running
"pkgparam -R "$alt_root" SUNWcsu" (SUNWcsr)
Wonder if something similar for Linux exists? I know that 'uname -p' works for the current system, but I am looking to find arch for a system mounted at some root.

Ubuntu :: Processor Type For New Computer Build?

Jul 21, 2010

A processor is very important to me and I'm curious what processor to get for a new computer build. I will be using Ubuntu for most things except iTunes, HD movies, and a few low spec requiring games on Win 7. I am building it as right now I have a half year old netbook that can do most things just fails at game play and movies but it's alright. And I have a desktop with just Ubuntu that's about the same quality but 8 years old. I want to build a computer that will be very fast for the next 4 years enough to get me to college and buy a nice laptop. I am on a small budget of around 500- 750 dollars. I have most things picked out but processor has me stumped. To me processor is a bit tricky to replace and I'd rather get a higher-end one to start and stick with that than buy another CPU two years down the road.

I don't mind upgrading RAM, GPU, and or even the HDD at a later point but I want to get the CPU as close to perfect as possible. First I heard AMD processors tend to be a bit hot. I was wondering what cooler is $50 or less that does a great job at cooling a AMD AM3 socket CPU. I do plan to overclock a very small bit perhaps up to .3 GHz plus max. First I was thinking a nice core i5 at $200 and never really checked anything else. Then, I was thinking a hexa-core at 2.8 GHz I think but decided too much and didn't need six cores. The AMD socket type also supported USB 3.0 which I instantly fell in love with. Then I found a quad core Phenom II x4 black edition at 3.20 GHz for around $160.I liked the core unlocker and it looked incredible. Now I'm rethinking a bit again.

I found a dual-core that is same thing as the other AMD one above except well only two cores. I think that would do me fine I'd I'd save $60 by getting 2 less cores. With the things I use a computer for (Ubuntu, Win7, HD quality playback, minor gaming like Runescape, and small multitasking like openoffice a browser or two and perhaps some pictures, game or movie.) I also want to be able to do this quickly for the next 4 years without a hiccup or at least to a minimum if possible. I really don't want to upgrade CPU once I get that bad boy in there. I also want it ready for higher versions of Windows like Windows 8 is supposedly coming sometime in 2012 I've heard. I just want the best CPU to be fast and efficient, run cool, and work well for me for the next 4 years.

Fedora :: Detecting USB Devices On Virtual Machine

May 21, 2010

I am running federa 12 and just recently installed virtual Machine Manager. I've created Virtual machine and installed Windows XP on it. Everything is running OK, as far as I can see. I've installed software to manage and download pictures from Cannon camera, but I am not able to make USB port available to this Virtual machine. I tried to add hardware in VM, but not sure if I should go for STORAGE option, or PHYSICAL HOST DEVICE. I tried second option, and selected USB device. Now I've got UB hub available, but still cannot see anything attached to it (camera in my case, or USB stick with pictures).

General :: Determine If A Multi-processor Machine Is Overloaded?

Jun 29, 2011

What is the best way to determine in Linux if a multi-processor machine is overloaded? I thought load was a good measure but I run a large number of tasks which don't consume a lot of CPU but which drive up the load. A 4 processor machine has a load of 66 right now according to top for example but mpstat reports that the all CPU idle time is 89%.

Ubuntu Servers :: How To Configure Kernel For A Many-processor Machine

Jan 2, 2011

I have Ubuntu 10.10 Server installed on a 32 core machine(quad AMD Magny Cours 6128 ), and I was wondering what kernel configuration would optimize its performance?So far, I have only found the obvious configurations that are checked off:

1) Processor type and features ---> Support for big SMP systems with more than 8 CPUs
2) Processor type and features ---> Maximum num of CPUs
3) Multi-core scheduler support

Is there anything else I should consider?I plan on running multi-threaded programs with moderate amount of inter-processor communication, shouldn't there be some options related to the shared memory?

Software :: Get Maximum Performance On A Multi-processor Machine?

Jun 30, 2011

I have a multi-threaded app using pThreads that runs great under Windows on my 4 core machine - all four cores get maxed out processing parts of a large file. I recompiled the same code to run on Red Hat linux on a 64 CPU machine - but from I can tell when it runs - it gets stuck on one core. "mpstat -P ALL" shows the cores are barely loaded. I have tried sched_affinity, sched_priority and SCHED_FIFO - nothing has helped. Any ideas on getting more performance?

Ubuntu :: Changing File System Type To Another Filesystem Type - Does It Effect On Data?

Feb 4, 2011

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5

previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal

After doing(changing the file system)this one ,i couldnt see the d:drive data

By doing that

1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.

2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.

Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)

I had very imp data in d:drive

Just to double check my work, I ran the following code:

Ubuntu Networking :: Cannot Ping KK Machine, Internet/network ON Machine Works?

I have an ubuntu kk laptop connected via wireless to my mixed network (xp, win7, other ubuntu), but i can not ping said machine or connect via ssh. Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

Ubuntu :: Numbers To Put In Linux Machine Can Connect / Print To Windows Machine?

Apr 16, 2011

I remember it being really easy to add a printer attached to another computer using Ubuntu, but I don't remember exactly what made it so easy. All I know is that now that I have switched to Kubuntu the process has become much harder because now I have to find out some special locations, numbers etc. for it to connect to the printer. It's connected to a Windows XP machine on the other side of the house.
It says alot about 'contacting the network administrator' if I am unsure about what to put in. But I am more or less the network administrator. how to find out what numbers to put in so that my Linux machine can connect and print to the Windows machine? Or maybe someone knows a few commands to share? I go to Applications > Settings > System settings, Printer configuration, New Printer, New Network printer, and then there are a few options but I don't know which one to choose. Windows Printer via Samba, I guess? Then in the box that says smb://[enter stuff here] I need to put in info but I don't know how to find that info.
