I am developing a code where I need to store the planes of an object in a tree & also i need to store it in a list for further processing ... when I try to allocate using malloc the memory allocation when i checked this in internet , I came to know that it may because the memory that I am trying to allocate may be more than the size_t variable.
View 9 RepliesI 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.
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.

I'm trying to install deluge via ssh and my vps has 512mb ram and is only using 11% of it prior to running the code.
I'm afraid I have a huge issue with my newest Fedora 14 server. I recently migrated to Fedora 14 from Centos 5, which was very stable, but had ancient packages and libraries and my users were revolting...The machine is a HP ProLiant 360 G7, with 12G RAM and 6 SAS drives in RAID 5.After I migrated to Fedora 14, I noticed that for some reason, during the course of about 24 hours, all usable RAM "disappears" and applications are forced down to swap space. Needless to say I didn't have this issue on CentOS.
The server does heavy IO as per it's function (it's a heavily loaded file processing server and user simulation computing station among other things, which causes lots of random IO), so I thought it may be the cache, but then I realized it cannot be - because obviously Linux will use onyl "unused" RAM for caching and frees it up as soon as an app need it. Then, I thought to check the "slabtop" to see what's going on in Kernel memory. Unfortunately I don't have the screenshot from the time just before the latest crash, but there's a certain value displayed by slabtop, which slowly, byte-from-byte creeps over all available RAM, eventually forcing applications down to the swap. This is malloc-64, and as you can see from the bellow copy-paste, it's building up again even now...
Code:
Active / Total Objects (% used) : 9118075 / 9153600 (99.6%)
Active / Total Slabs (% used) : 152157 / 152157 (100.0%)

View 4 Replies View RelatedLet's analyse this While registering a Char deriver to kernel think that we had allocated memory using any of malloc/kmalloc/vmalloc.
If we forgot to Free that allocated memory while unregistering, will that memory be allocated aside or kernel clears it...?
clarrify the below points:1) Where does the Kmalloc/Vmalloc/get_free_pages/malloc Allocates memory in which space is it Kernel/User?2) Coming to Hardware Point of View is where Kernel/User Space Memory Allocates is it in RAM or any.?3) In Device Drivers, how Open Call get to know whether the hardware is connected/not?

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.
On my windows console, i have installed sun virtualbox. I only have 768MB ram and so i downloaded a trial version of eboostr. I thought it would work, but when i tried an install of 11.2, also, i tried a debian install, it did the same thing, it froze up in the middle of the install with the error Code: unable to allocate and lock memory. I guess that eboostr doesn't work, but is there a way to use a flash drive as ram in virtual box?

Is there a way to hook calls to new/malloc, delete/free in C++? I tried the following methods: LD_PRELOAD -> fails for malloc, because dlsym seems to depend on malloc -Wl,--wrap,malloc -> doesn't work for 'new' gcc hooks -> doesn't work always, e.g. for uclibc there are no hooks Are there any other methods I could try?
