I went to an interview last week and there was this guy who asked a simple question that i have been trying to solve for a couple of days. I tried google but i just cant get the search keywords right. The result were just useless. Well, the question is : "How can we allocate a limited memory to a process before we start its execution" well, the question is related to an X11 system so may be some flags must be set to limit its memory.

View 2 Replies View RelatedI'm running a quite complex model, and it's taking me around a week to complete the run, and one of my colleagues says that he can run it in one-two days. After looking to several forums to know how does it work, I've seen how the memory is used (using the command ps -A --sort -rss -o comm,pme), and the model run just takes 0,3% of the memory. I bought a 4 cores and 8gb of RAM laptop to be able to run the model fast, but I don't know how to allocate the use of the memory to concentrate it in developing that task. Is that possible?

I just switched over to openSUSE about a week ago from Ubuntu and I just purchased an Asus N13 PCI-E wireless network adapter which uses an RALink 2860 chipset. I plugged it in and openSUSE was able to detect it and everything but when I went to go configure it using YaST, it wouldn't be able to scan for networks.
So, I reinstalled my old adapter, downloaded the latest source from RALink and compiled the drivers. When I tried to use insmod on the new .ko that was compiled, I got the "Could not allocate memory" error.
If you need dmsg logs or anything else, I can reinstall the card and get those.
I wrote a program in lcc in windows and I have to write it in gcc in unix. In lcc there was an option to use more memory than the default for the stack. The following code is working in lcc but in gcc it gives segmentation fault:
#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include <time.h>
int main()

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.

I guess that eboostr doesn't work, but is there a way to use a flash drive as ram in virtual box?

View 1 Replies View RelatedI have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.
However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.
I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.
I need to monitor the amount of free physical memory on Linux from within a large C program. The sampling will occur very frequently, so the measurement cannot be performance intensive. The fact that Linux uses much of the theoretically free memory for cache and buffers means that just measuring the free pages is not sufficient. Using free + cache + buffers gives an overestimate as not all cache/buffers can be freed, but I could get a rough idea of how much generally can't and subtract that from the answer.
Possible options that I've come across so far are: Parsing /proc/meminfo - but that involves reading from file which is slow. Extracting the free, cache and buffers values from the output of the Free command - but is there a quick way to do this? Parsing the /proc/freemem file produced by the API here - but this is again reading from file. Is there a way to get that output directly? Speed is an extremely high priority, and the answer it must accurately represent the amount of memory that my program could expand into (to within a few Mb).
I have written a program which uses port 5000. I need to restrict other programs use this port when I'm not running that program. In Linux are there a mechanism to restrict port 5000 accesses from other programs.

My memory_limit in php.ini is set to 20M. I tried to increase that however it didn't quite work. PHP seems to allocate all possible space and return that message every time i try.
