allocation

Is there a Python module that would enable me to place instances of non-trivial user classes into shared memory? By that I mean allocating directly in shared memory as opposed to pickling into and out of it. multiprocessing.Value and multiprocessing.Array wouldn't work for my use case as they only seem to support primitive types and arrays thereof. The only thing I've found so far is POSH , but it hasn't changed in eight years. This suggests that it's either super-stable or is out of date. Before I invest time in trying to get it work, I'd like to know if there are alternatives I haven't

How to write a thread-safe and efficient, lock-free memory allocator in C? By efficient I mean: Fast allocation & deallocation Optimal memory usage (minimal wastage and no external fragmentation) Minimal meta-data overhead paxos1977 http://www.research.ibm.com/people/m/michael/pldi-2004.pdf This paper presents a completely lock-free memory allocator. It uses only widely-available operating system support and hardware atomic instructions. It offers guaranteed availability even under arbitrary thread termination and crash-failure, and it is immune to dead-lock regardless of scheduling policies,

I followed this link: Replace default STL allocator to replace the standard allocator with my own custom allocator. But I am getting this error: /grid/common/pkgsData/gcc-v4.8.3/Linux/RHEL5.0-2010-x86_64/include/c++/4.8.3/bits/allocator.h:92:45: error: expected template-name before '<' token class allocator: public __allocator_base<_Tp> ^ Somehow allocator.h file is not able to find out my custom allocator class. I used GCC:4.8.3 I added bits/ folder inside my source include folder, and created c++allocator.h. Inside this file defined marco similar to GCC provided c++allocator.h ( https://gcc

My C program is crashing and I am too new to figure it out. It's very simple so far and I imagine the code is enough to figure out what is going wrong. I am simply trying to read a file line by line. I will double the memory of a structure once I am out of memory. If this is not enough information, I will give whatever else you need. Thank you very much for any help, as I have been stuck for hours now. /* John Maynard 1000916794 7/15/2013 HW-06 */ #include <stdio.h> #include <stdlib.h> #include <string.h> #define N 100 struct course { char subject[11]; int catalogNum; int sectionNum; int

I'm new to programming, I've been making an app for the last 3 months and learned a few things. But I haven't come across to how to solve this issue. I've been using Parse.com as my server, sending pictures, saving user data etc. With all of this data the app keeps crashing if I open some activities more than a few times, particularly activities with pictures. Now I have compressed the pictures and made them max 400x400 in resolution. But somehow the allocation is out of memory keeps popping up. Does anyone know any methods with which you can solve this? Because when the app crashes in Android

Wordpress Site Centos6 Apache 2.2 PHP 5.5 RAM 4gb I have the following php error message: Fatal error: Allowed memory size of 268435456 bytes exhausted The problem is that I have allocated 512M on php. I have changed the proper variable in php.ini . Also I have edited my wp-config.php with defining the following: define( 'WP_MEMORY_LIMIT' , '512M' ); define( 'WP_MAX_MEMORY_LIMIT' , '512M' ); I couldn't figure out why I'm having the message that I have allocated only 268435456 bytes even after changing the above mentioned settings. Is there any other settings to be changed? php.ini details:
