General :: Which Is Better On Low-memory Machine / 32 Or 64 Bit?
May 9, 2010
I have a moderately old laptop, with an AMD Turion 64 X2 TL-50 processor and 438 MB RAM (after the graphics takes a fair old chunk it seems). I've currently got lubuntu 64-bit on it, and am not 100% happy with the performance. (Though I'm very pleased with the system in other respects). I'm wondering whether 32-bit GNU/Linux might use less RAM, and thus result in better performance.Or should I be more focussed on other things if I'm looking to boost performance, like maybe the hard drive, or stopping the CPU throttling down (/proc/cpuinfo reports 800MHz)?

I need to buy some more RAM for my old PC. I know there are Windows applications that can tell me the type of RAM I have installed. I am running Ubuntu and I was wondering if there was an alternative that would tell me about the RAM I am using.

I have a Red Hat 5.3 virtual machine that has 3GB memory. I just upgraded the memory to 4GB, however when I run free -m it still only recognizes 3GB. Is there something else I need to do?

I'm running Fedora 11 (2.6.30.10-105.2.4.fc11.i686.PAE) 8 GB memory on a AMD Phenom(tm) II X4 965 Processor, 4 core server I just built.The problem I have run into is any virtual machine that has >1024 MB memory assigned to it will not boot. As along as it has 1024 MB or less it boots fine.The symptom you see is a very quick message "Booting from hard disk" the screen then goes blank, you can't login through SSH, and can't ping the network address so I know it's not some crazy video problem hiding the boot process.The attachment are messages from a failed boot attempt.

I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

I've been running my Dell Mini 9 with the latest alpha for 10.04 since January, but over the weekend I botched things pretty badly and decided to go back to 9.10.I saved my home directory to another machine, and proceeded to install from a 9.10 USB disk. Things didn't go terribly well (I kept seeing "devkit-disks-daemon" crashing) but the install did complete. I shutdown the netbook, yanked the USB drive and powered it back on only to be greeted the grub menu. Choosing any option yields: Code:error: out of memoryPress any key to continue...I did a little searching in places like:HTML there is no mention of that problem there, and running though the command line instructions has the same results. (the linux command seems to be the problem)I've tried re-installed grub from the directions on the page but it is failing with:
Code:
cp: cannot stat '/mnt/boot/grub/ufs1.mod': Input/output error
When I look up that file I see:
[code]...

This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.

I found from command 'top' that 8GB memory are used. However, using command 'ps' with some options to grep the running processes and then summing up the memory used by the running processes are less than 2 GB. Where has the used memory gone ?

I have some file tools on a mint machine that I would rather not install on my mac laptop. Mainly because of the vastness of apt-get and the low risk of installation failure. Anyway, every so often I have a file that I want to process in place using some remote tool. Both machines can ssh right in to each other so I was figuring there must be some script or tool out there that would allow me to type out something like remote [file] [tool & args] to send my file to the other machine, get it processed, then get it back.

I'm know very little about Linux but decided to set up a machine running Drupal CMS on a Debian machine and it won't go. The folks at Drupal have tried to help but it seems the Debian OS won't do it's PHP thing for Drupal.
That means i'll have to start at the START I guess.

I am new to C and linux. My code below does arbitary writes but I cant figure out where or how it does it.
I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.

we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

I am monitoring physical memory in a server I administer, and my hardware provider told me they had increased physical memory size to 4Gb... However, using several tools (free -m; top; dmesg | grep Memory; grep MemTotal /proc/meminfo I discovered that I actually have 3Gb, not 4... But, my doubt comes from the fact that dmesg | grem Memory tells me I have 3103396k/4194304k available The first number is effectively 3Gb, but the second one, is 4! so, why I am looking at this two different numbers?

I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.

I am writing an application that wants to access periphals registers outside the standard (allowed) memory area.
Doing so gets me "segmentation fault".
I know, this is natural behaviour.
One way of getting around this is writing the module which has to be loaded by linux. I will consider this some time later.
For now, I want to come to some quick result and allow linux or gcc compiler to write to those memory areas of periphals. Is there a direct way to do so?

Is that possible that SHM shared memory is counted as cache memory on Linux with kernel 2.6.18?If find it really odd since this memory is not file backed, but I have a piece of code that loads data using shm_open+mmap, and it generates an amount of cache memory in /proc/meminfo that corresponds exactly to the amount of shared memory (I load that data from a file but I am using posix_fadvise(fd,0,0,POSIX_FADV_DONTNEED) to ensure this file is not cached and I made sure that it is working as expected). As far as I know SHM memory was not tagged as cache memory with kernel 2.6.9.If it is the case it is really unfortunate since normally cache memory can be considered to be part of the "available" memory since it can be flushed promptly but this is clearly not the case with SHM memory... Is there an easy way to get the total amount of used SHM memory on a system?

I have been setting up a vps I got out with bhost.net, with CentOS installed. I've been learning and have set up everying I need with the exception of ftp/sftp.
Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.

Fairly new to Linux, using Red Hat ES 5.5 with 16GB of memory.Looking at migrating the server to a VMWare VM, but I need to figure out how much of the 16GB I am actually using.What are some ways to tell the true amount that I need.I know that Red Hat allocates most of the memory just so it is ready to be used, so that throws me off a bit.
