• Best memory allocation strategy for iOS ?

  - by Mr.Gando

  Hey guys, I'm debating myself about memory allocation on iOS. I write most of my code in C++ and I really like using ObjectPools, FreeLists, etc. In order to pre-allocate a lot of the stuff that I'll be constantly "alloc/dealloc" during the course of my game, ( like particles, game entities, etc ). Still on iOS, it's not like we are developing…

• Swap is not copied back into physical memory

  - by GradGuy

  I have a question regarding swap and physical memory. Often times I run a program that requires a lot of memory and as a result I can see some of the data is copied from the physical memory into swap. However, once the program is terminated, and the physical memory is freed I can still see a considerable amount of data on swap which…

• NPOT texture and video memory usage

  - by Eonil

  I read in this QA that NPOT will take memory as much as next POT sized texture. It means it doesn't give any benefit than POT texture with proper management. (maybe even worse because NPOT should be slower!) Is this true? Does NPOT texture take and waste same memory like POT texture? I am considering NPOT texture for…

• Aide On a Low Memory System

  - by Jason Mock

  I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2,…

• Fastest Memory (within reason) for a MotherBoard [on hold]

  - by sampson

  I was wondering if it would be OK to use DDR3 3000 memory with Asus Maximus VI Impact MotherBoard, Intel® Core™ i3-4130T Processor and Steamcom's FC8 case The purpose of this machine is for a HTPC (Home Theater Personal Computer) system, only, no gaming. The case is fan less as is the CPU cooling system. Also,…

• ruby/ruby on rails memory leak detection

  - by Josh Moore

  I wrote a small web app using ruby on rails, its main purpose is to upload, store, and display results from xml(files can be up to several MB) files. After running for about 2 months I noticed that the mongrel process was using about 4GB of memory. I did some research on debugging ruby memory leaks…

• Accessing outside the memory allocated by the program. (Accessing other app's memory)

  - by Auxiliary

  Is there a way to access (read or free) memory chunks that are outside the memory that is allocated for the program without getting access violation exceptions. Well what I actually would like to understand apart from this, is how a memory cleaner (system garbage collector) works. I've always wanted…

• Memory usage in Flash / Flex / AS3

  - by ggambett

  I'm having some trouble with memory management in a flash app. Memory usage grows quite a bit, and I've tracked it down to the way I load assets. I embed several raster images in a class Embedded, like this [Embed(source="/home/gabriel/text_hard.jpg")] public static var ASSET_text_hard_DOT_jpg :…

• How do I mock memory allocation failures ?

  - by Andrei Ciobanu

  I want to extensively test some pieces of C code for memory leaks. On my machine I have 4 Gb of RAM, so it's very unlikely for a dynamic memory allocation to fail. Still I want to see the comportment of the code if memory allocation fails, and see if the recover mechanism is "strong" enough. …
