I need to allocate a % of the total system memory for a buffer but what is the best method to determine how much memory is in the system? So far the only way I have found is to get the pages of memory:
Code:
long sysconf(_SC_PHYS_PAGES)
Is that the only option?
I would like to know if there is a linux command to verify the amount of memory used by a program. The programs I am using were compiled with gfortran.

View 7 Replies View RelatedI want to calculate the total amount of memory used by the system, Someone please confirm if the below formula is correct.Quote:
((memUsed-mebBuffers-memCached)*100)/memUsed => totalMemoryUsed%
Code:
free -o
total used free shared buffers cached
Mem: 8167004 8115292 51712 0 87680 1444676
Swap: 8388584 3252996 5135588
((8115292-87680-1444676)*100/8115292) => 81%
As per the above calculation 81% of memory is used.Is this correct? and if so Am I running out of memory?what is the limit in % that I should maintain for a better performance?
When I run ardour sound editing I get this message , but it starts ok Your system has a limit for maximum amount of locked memory! This might cause Ardour to run out of memory before your system runs out of memory. You can view the memory limit with 'ulimit -l', and it is normally controlled by /etc/security/limits.conf
bash-4.1$ ulimit -l

My problem is I installed Zone Minder for camera security and I'm testing it on my laptop with the built in webcam and everything seems to work perfectly except when I try to view the live feed from the camera, it's just a black box. No video.
I checked this website and it's exactly the problem I'm having with a fix for it but his fix doesn't work. He says to type:

I am trying to understand a large amount of allocated memory that seems not to be accounted for on my system.I'll say up front that I am discussing memory usage without cache and buffers, 'cause I know that misunderstanding comes up a lot.I am in a KDE 4.3 desktop (Kubuntu 9.10), using a number of java apps like Eclipse that tend to eat up a lot of memory.after a few days, even if I quit most apps, 1 gb of ram remains allocated (out of 2 gb).this appeared excessive, and I took the time to add up all values of the RES column in htop (for all users).the result was about 1/2 gb.am I trying to match the wrong values?or could some memory be allocated and not show up in the process list?this is the output of free

I am trying to write a script to calculate the total amount of installed memory to use during an anaconda kickscript, so the swap file is created at 2 x the installed memory. I so far have the amount of installed RAM DIMMS but need a way to total them up and produce a varible I can use in the pre section of the install.
Code:
dmidecode -t 17 | grep Size | awk ' { print $2 }'
Output:
2048
2048
Note: on some servers there could be from 1 DIMM up to 16 DIMMS installed so the script needs to be able to handle this. I also can not use bc as it does not exist during the install stage. I am guessing I need a while loop to do this and use expr but do not know where to start for this logic.

I am having a problem with some users maxing out the available RAM, causing such sever slowdowns the machine essentially crashes. My servers are Dell Power Edge's running Ubuntu 8.10 Server Edition (Not my choice). I would like to set a maximum limit on the amount of ram a user can utilize. This morning I experimented with setting limits via /etc/security/limits.conf and using ulimit. Neither of them prevented my test program, a simple infinite loop of mallocs, from crashing the server.

I have 4GB RAM installed on my PC (ASUS P7H55M-BR, Intel i3 530 2,93Ghz). Onboard video has 32 MB (BIOS config).
It should be this way (or maybe not?):Each slot has 1GB of RAM memory: 4 x 1024 MB = 4096 MB.
Now, subtracting the video memory: 4096 MB - 32 MB = 4064 MB.

View 1 Replies View Relatedwe 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 5 Replies View RelatedI made the fatal mistake of hibernating on my Lenovo T61. Ubuntu wouldn't wake up after that, I tried pressing all kinds of key combinations and nothing. So I did a hard shut down and now Ubuntu won't start. On the grub menu I chose Ubuntu with Linux 2.6.35-7 normal mode and it just shows the screen that says "Ubuntu 10.10" and the four dots underneath indicating loading.
So I tried recovery mode and it stops at:
fsck from util-linux-ng 2.17.2
/dev/sda5: clean, 688078/4988928 files, 15488354/19939072 blocks
I also tried unplugging the laptop and removing the battery and putting it back in and plugging and restarting. Nothing changed. Then I tried restarting without the battery in and now the normal mode just shows a black screen and a flashing cursor. I also have the USB stick I created to install Ubuntu, which worked back then, but now, it won't start from the stick, I checked the Bios options and the USB is the first boot device, I really don't know how else I can make it start from the USB.
I have a large collection of music albums sorted in folders which are named like this: "Zombie Ritual - 2004 - Night Of The Zombie Party" (%{artist} - %{year} - %{album}).

It will be hard to do this manually. I tried to use EasyTag and Kid3 to do this, but they cannot add bitrate to tags.
