I am looking to buy some memory for my netbook. Currently I have 1 GB of DDR3 memory. However, the specification says that 2 GB of memory is the max. However, when I do the following it says that 4GB is the max:

I am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)

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 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.

View 2 Replies View RelatedI 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?

View 9 Replies View RelatedI 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?
View 4 Replies View RelatedThis 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.

View 7 Replies View RelatedI 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.
The whole code is written in C, C++, and Fortran. Is it possible to make it to use more than 4GB memory. Now it is always crashed when it reaches 3GB memory. If it is possible, how to set up the compiling options (or configure flags)? We can use gcc, g++, ...or intel compilers our OS: Fedora 12 x32

I am using Fedora 8 in my PC and i'm trying to create a shared memory (below is the sample program) i'm getting error while creating shared memory. Can anyone pl tell what is the possible cause for this.
View 2 Replies View RelatedI just upgraded my Dell e1505 Laptop from 2GB of memory to 4GB of memory. I upgraded because I was under the impression that x86 64-bit OS would be able to read that much memory.
Vista Ultimate 32-bit, reads 4GB installed, but only 3.2GB of physical memory. Which I understand, being a 32-bit OS.
Fedora 10 x86 64-bit though, also only sees 3.2GB
p.s. - Could it possibly be that I bought the wrong memory? The memory that came with my laptop was DDR2 PC2-5300, but when I search on Dell.com to purchase memory using my service tag, I get results for DDR2 PC2-6400 - which is what I bought. (Kingston HyperX 4GB (2 x 2GB) 200-Pin DDR2 SO-DIMM DDR2 800 (PC2 6400)
I also did searches on xxx.crucial.com and xxx.newegg.com and both stated DD2 PC2-5300.
The following is what my BIOS reads:
- Intel(R) Core (TM)2 Duo Processor 2.00 GHz
- Memory Installed: 4096 MB
- Memory Available: 3327 MB

At Present my Desktop has only 0.5 Meg Memory, F14 works well, F15 refused to Upgrade a 750 MB minimum I have gone back to 14.

View 14 Replies View RelatedI'm trying to understand the performance of my machine and memory usage just isn't adding up. When I run top it will typically show 301M of 308M used but the total of everything in the RES column is no where near 300M and the total of %MEM column isn't more than 20-30%. So how do I figure out what is using all the memory? Then is there some way to control it to optimize performance?

View 1 Replies View RelatedI just installed Fedora 13 onto a "new" (to me) box, and everything seems mostly fine, except that I only seem to be able to use about 900.2 MiB of 991.4 MiB of RAM memory, according to System Monitor. I haven't set up a swap partition yet, so the problem became very, very, very obvious. When I get to about 890 MiB usage, everything goes very quickly downhill, locking up, etc. The peak I saw was 900.2 MiB. What's going on? Does this have anything to do with the system being 64-bit? Might the memory be bad?
View 14 Replies View RelatedI've an 8GB swap (I know, overkill, but I don't have space issues, and I'd rather have too much instead of too less). The problem is that my physical memory fills up, and the system crashes, but swap usage is ALWAYS 0%
Mem: 8060580k total, 5193436k used, 2867144k free, 1013788k buffers
Swap: 8388604k total, 0k used, 8388604k free, 2262112k cached
Setting aside the fact that I can't trace why memory usage goes up to 8GB with just firefox/terminals/pidgin, why isn't my swap EVER used?
Also, if I run
Code:
# top
2301 hugo 20 0 1887m 665m 38m S 19.9 8.5 267:38.63 firefox-bin

(The rest are all "0 0 0 0 S 0.0 0.0")
If add up all of the RES columns, I get <1GB. If I add all the VIRT column, I get about 3GB. Where's the other 2GB being used? This goes up all the way to 8GB, without being able to add up where my memory's going.
I have been noticing a distinct slow down in my Fedora of late, and today, with no program running, I called up System Monitor and low and behold, Firefox was running in memory, and taking up 1/2 (50%) of 2 GB of RAM! How does one stop this behaviour? How do I make Firefox stop running when I close it?
