Do memory channels use separate pins for data bus in Intel i7-4600U?

问题 i7-4600U datasheet says that SA_DQ[63:0] is used for memory channel A. And SB_DQ[63:0] is used for memory channel B. So my understanding is that memory channel A and memory channel B use different processor pins for each own's data bus. Is my understanding correct? 回答1: The presence of the of SA_DQ[63:0] and SB_DQ[63:0] pretty much says it all. The are two physical channels. If you still need a secondary "prof", you can also check the math of this statement in the datasheet Theoretical

Visual Leak Detector VS2019

Visual Leak Detector 介绍 （翻译仅供参考） Visual C++ provides built-in memory leak detection, but its capabilities are minimal at best. This memory leak detector was created as a free alternative to the built-in memory leak detector provided with Visual C++. Here are some of Visual Leak Detector’s features, none of which exist in the built-in detector: Visual C++提供了内置内存泄漏检测，但其性能很低。这个内存泄漏检测器被创建为用Visual C++提供的内置内存泄漏检测器的免费替代。这里有一些内置检测器中没有的Visual Leak Detector的特点： Provides a complete stack trace for each leaked block, including source file and line number information when available. Detects most, if not

Delphi - Access violation when try to overwrite an instruction with DLL Injection

由 て烟熏妆下的殇ゞ 提交于 2020-01-25 19:01:27
问题 Good morning. I'm trying to learn about DLL injection, so I've wrote a little software, that just gets a String, compares with StrCmp() and if the input was equal "Winner", the software gives a Good boy message, with the porpouse of learn DLL injection. So I write a DLL that loads a Form when inject, the porpouse is using the DLL injection, to modify the Instruction of comparison( JNZ(74) to JMP(EB)), and make the software, accept any string. My DLL code is: library Project2; uses SysUtils,

Is it possible to trace references between objects in Flash, in the same way as the Flash Builder profiler?

问题 I'm trying to find memory leaks in a fairly large Flex application and I'm tired of using the paltry tools Flash Builder makes available. Specifically, I want to analyse the relationships of objects in memory, using the same information Flash Builder's tools appear to have access to. I.e. which objects are in memory, and which objects they have references to, and have references to them. Given that information, I want to construct a directed graph whose nodes are live objects and whose edges

Growing memory usage in MATLAB

由 北城以北 提交于 2020-01-25 18:38:16
问题 I use MATLAB for programming some meta-heuristics. Recently, I have been working on an algorithm for solving an industrial engineering problem. My problem with MATLAB is getting "out of memory" errors. Now I'm trying some suggestions from Mathworks and Stackoverflow (Hope they will work). However, there is one thing I did not understand. During the run of the algorithm in MATLAB (it takes 4000-5000 cpu sec for a medium sized problem), even though I preallocate variables, code does not demand

How do you iterate through a pitched CUDA array?

问题 Having parallelized with OpenMP before, I'm trying to wrap my head around CUDA, which doesn't seem too intuitive to me. At this point, I'm trying to understand exactly how to loop through an array in a parallelized fashion. Cuda by Example is a great start. The snippet on page 43 shows: __global__ void add( int *a, int *b, int *c ) { int tid = blockIdx.x; // handle the data at this index if (tid < N) c[tid] = a[tid] + b[tid]; } Whereas in OpenMP the programmer chooses the number of times the

Objective-C中的Block(闭包)

转自http://www.cnblogs.com/ludashi/p/3903054.html?utm_source=tuicool&utm_medium=referral 学习OC有接触到一个新词Block（个人感觉又是一个牛气冲天的词），但不是新的概念，不是新的东西。学过Javascript的小伙伴对闭包应该不陌生吧~学过PHP的应该也不陌生，在PHP5.3版本以后也支持闭包, 也就是OC中所提到的Block。 到底什么是闭包或者block呢？用大白话说就是匿名函数，也就是在函数中可以包含这函数。就是在函数中可以定义匿名函数然后在函数中调用。学习OC中的block之前也小担心一下，Block在OC中属于高级的部分，心里有又有个疑问：学起来难不难？看过Block的部分，感觉Block挺好理解的，用起来也挺顺手的，Block没我想象中的那么难理解。 废话少说，学习一门新的编程语言是少不了代码量的支持的，所以代码是少不了的。下面就通代码来认识一下OC中的block的使用。 Block基础部分 1.Block的声明 Block的定义和函数的声明差不多，就是把函数名改成(^blockName)即可。下面是block声明的代码。 有返回值的 1 int (^sumBlock) ( int , int ); 无返回值的 1 void (^myBlock)( int , int ); 2

The game I am making consumes way too much memory [duplicate]

问题 This question already has answers here : Memory not getting released in WPF Image (2 answers) Prevent Memory Bloat When Loading Multiple Images In WPF (2 answers) Closed 2 years ago . I am making a game on C#. The problem is, that it uses large amounts of RAM, for the games of such type and quality. I'll try to give a short, but good enough description. I, of course, won't give full code, but try to show what I think is relevant. The game has some grids, where each grid represents a game room
