不是内存泄漏吧,你是什么软件的提示啊

从意思看,应该是从软件保留的内存空间分配

allocate主要是按照计划地分配,dispense是施舍的意思更多些,distribute主要说发送这个动作。下面是它们几个的解释你看看1、allocate vt. 1. (为特定用途而)把…拨给,把…拨出;把(物资、资金等)划归: The Government has allocated funds for housing.政府已为住房建筑拨给资金。 2. (按股份、计划、规定等)分配,分派,派定,配给: We have allocated this room to you.我们已把这间房子分给你。 vi.【计算机】分配,指定,保留2、dispense vt. 1. 分发(施舍物品等),分配,给与,分给,施与: The Red Cross dispensed charity to refugees.红十字会向难民放赈。 They dispensed the money to charity.他们把钱捐给慈善事业。3、distribute vt. 1. 分发;分送;分配,配给: They distributed political pamphlets in the hall.他们在大厅里散发政治小册子。 The relief agency will distribute the food among several countries.救援机构将给几个国家发放食物。 vi. 1. 分配;分发;分送 2. 【数学】运用分配运算;分配

allocate 啥时和to搭配,啥时和for搭配?

"for"一般表目的,"to"一般表对象(1)allocate for/to sth. 或allocate ...for/to sth.搭配。如果是表达“为达到某特定目的”分配(allocate)就用介词"for”,如“为救灾拨款一百万美金”:One million dollars was allocated for disaster relief. 或allocate one million dollars for disaster relief如果是表达“给某特定的事(物)”分配就用介词"to",如“会拨更多的钱到灾区”:More money is being allocated to the disaster area. 或allocate more money to disaster area(2)allocate to sb. 或allocate ...to sb.搭配。“给某特定的人(团体)”分配用介词"to"。

allocated-allocated

Cantiga HDCP Mode 这个我查了下。HDCP 是高带宽数字内容保护技术。按照字母顺序应该是高带宽数字内容保护技术模式,这个Cantiga 没有翻译出。DVMT是动态显存分配技术,这个容量的分配,依内存容量而言。Total Graphics Memory 这个是要分配给显卡的内存,同样也要依内存容量而言。这里的内存就是你主板上插得内存条。集成显卡,的显存一般不是很高(相对于独立显卡)。如果图形处理量加大,就需要借用内存上的空间来存储数据。看一下集成显卡的容量,如果在2G左右,那么就没有必要共享主内存的容量。集成显卡的设置,第一,要看集成显卡的显存,其次就是主内存的容量。很简单,主内存存储CPU处理和运行的数据,它的大小,很大程度上决定计算机的运行速度。而显存是负责图形处理的。比如看高清电影,玩游戏,它也需要足够的内存来存储数据。BIOS Version 是BIOS 版本。就是 基本输入输出系统的版本。Ec Version 和M/B Version 应该是某种东西的版本号,只不过用的都是缩写。

Python中list的实现

原文链接 这篇文章介绍了Python中list是如何实现的。 在Python中list特别有用。让我们来看下list的内部是如何实现的。 来看下面简单的程序,在list中添加一些整数并将他们打印出来。 正如你所看到的,list是可以迭代的。 Python中list是用下边的C语言的结构来表示的。 ob_item 是用来保存元素的指针数组,allocated是 ob_item 预先分配的内存总容量 让我们来看下当初始化一个空list的时候发生了什么 L = [] 非常重要的是知道list申请内存空间的大小(后文用allocated代替)的大小和list实际存储元素所占空间的大小( ob_size )之间的关系, ob_size 的大小和 len(L) 是一样的,而allocated的大小是在内存中已经申请空间大小。通常你会看到allocated的值要比 ob_size 的值要大。这是为了避免每次有新元素加入list时都要调用realloc进行内存分配。接下来我们会看到更多关于这些的内容。 我们在list中追加一个整数:L.append(1)。发生了什么?调用了内部的C函数app1() 来让我们看下 list_resize() , list_resize() 会申请多余的空间以避免调用多次 list_resize() 函数,list增长的模型是:0, 4, 8, 16, 25, 35, 46, 58, 72, 88, … 开辟了四个内存空间来存放list中的元素,存放的第一个元素是1。你可以从下图中看到L[0]指向了我们刚刚加进去的元素。虚线的框代表了申请了但是还没有使用(存储元素)的内存空间现在我们在列表的第一个位置插入一个整数5:L.insert(1, 5),看看内部发生了什么。调用了ins1()当你弹出list的最后一个元素:L.pop()。调用listpop(), list_resize 在函数listpop()内部被调用,如果这时 ob_size (译者注:弹出元素后)小于allocated(译者注:已经申请的内存空间)的一半。这时申请的内存空间将会缩小。 Pop的时间复杂度是O(1)Python list对象有一个方法可以移除一个指定的元素。调用listremove()。 切开list和删除元素,调用了 list_ass_slice() (译者注:在上文slice list between element"s slot and element"s slot + 1被调用),来看下 list_ass_slice() 是如何工作的。在这里,低位为1 高位为2(译者注:传入的参数),我们移除在1号内存空间存储的数据5 Remove的时间复杂度为O(n)文中list的sort部分没有进行翻译 核心部分

什么是 allocated storage duration

动态分配的对象具有这种存储期storage duration就是存储期。storage duration决定生命期(lifetime)。在对象 X 的生命期内可以保证“X 的地址存储的一定是 X 这个对象的值”,超出 X 的生命期就没有这个保证了。在对象 X 的生命期之外使用对象 X,是“未定义行为”(undefined behavior)。C语言的storage duration有四种static。对象的生命期是整个程序。对象在程序开始运行前初始化thread。对象的生命期是整个使用这个对象的线程。对象在线程开始运行时初始化automatic。对象的生命期从当前块(block)的开头开始,到当前块(block)结束为止(对于 VLA,是从声明时开始,到当前 block 结束为止。不过因为对象的名字在声明之前都不能使用,大概也什么差别)。此外还有一类特别的对象具有automatic storage duration,它们是非左值(non-lvalue)结构体的数组成员(例如,当这个结构体是函数的返回值),具有temporary lifetime(临时存储期),对象在表达式执行时初始化,在完整的表达式执行完毕时生命期结束allocated。对象是动态分配的。对象的生命期从分配内存(例如使用 malloc 函数)开始,到去分配(例如使用 free 函数为止。thread storage duration是 C11 加入的,为了支持多线程。具有 temporary lifetime 的对象是 C99 加入的,这种对象的例子如下struct x {    int y[3];};struct x f(void) {    struct x a;    a.y[0] = 1;    a.y[1] = 2;    a.y[2] = 1437;    return a;}int main(void) {    int t;    t = f().y[2];     /* 数组 f().y 具有 temporary lifetime (这样它才可以隐式转换为指针,然后使用 [] 运算符) */}

Android 分析OOM工具介绍

如图1所示, 步骤 ** 1, 2, 3** 为打开Android Monitor并切换标签到monitor的过程 4, 5, 6 对应的图标和文字含义分别是 MAT 工具识别,并解析hprof文件, 有两种方式可以获得hprof文件 MAT并不能直接打开这两个hprof, 必须通过hprof-conv来转换一次 如图3所示,选中(过滤出MainActivity), 然后通过Objects可以看出它有8个实例 接着选中 com.example.wowo.MainActivity 然后右键选择 Merge shortest paths to GC Roots -> exclude week references 因为弱引用是会被回收的,所以排除掉更加容易发现OOM. 什么是OOM out-of-memory? Android下的APP运行在VM中(Dalvik or ART), 一个APP需要的内存是有限,这个值在不同的平台, 不同的手机上是不同的,当APP需要的内存超过了内存上限,就会引起OOM. 下面给出一个最基本的Android APP显示HelloWorld的例子. 这时如果不停的旋转屏幕, 这时通过观察Android Monitor里的Free和allocated的memory会发现 allocated 的memory会不断增加,而Free的memory会不断减小 这时通过图1中步聚5 dump java heap, 然后filter到MainActivity, 会发现MainActivity有多个实例 接着再通过MAT来分析, 图4所示 发现有很多FinalizerReference, 应该是与GC有关,由于旋转屏幕会导致MainActivity销毁并重新创建实例,而JVM在创建MainActivity实例时还有free的memory, 所以并没有触发GC,即原来的MainActivity的实例并没有被回收,所以多次旋转后,在free memory还有的情况下就会保存多个MainActivity的实例造成内存泄露的假象。当free memory 不够时,这时会触发GC, 会回收之前销毁的MainActivity的实例。 所以在查看OOM问题时,当allocated内存不断增大时,应该人为先触发GC(点击图1的4)。 如果allocated的内存没有下降,说明当前并没有可回收的实例占据内存了。 而在该例中,如果点击了initiate GC后,allocated的内存立即减少了。 Android Monitor看到MainActivity也就只有一个实例了。

为什么Manufacturing Overhead 不计入work-in-process.但是manufacturing overhead allocated

首先,M O/H 分为actual M O/H 和applied M O/H,在这里,后者就是你说的要allocated 的overhead,要和Direct Material (DM),Direct Labour(DL) 在一起,三个都要计入WIP。在这里applied M O/H可能要用到pre-determined overhead rate 和 hours 来算。其次,Actual manufacturing overhead 是后来算的,它包括IndirectMaterial (IDM),Indirect Labour (IDL) ,Others manufacture expenses。最后需要用actual M O/H和applied M O/H 比大小,如果Actual M O/H > Applied M O/H: Underapplied Overhead ,反过来是overapplied overhead. 差异应该计入COGS里。因为实际的overhead必须要整个生产过程都结束了才能知道,而wip必须是在生产过程中就要了解的,所以就需要applied M O/H,同时要记入wip里。但由于这只是估计的,所以最后要和实际的相比,差额要反应在减少,或者增加COGS的分录里,最后要反映在表里。

知识点9:动态内存分配(dynamic memory allocation)

Dynamic memory allocation sort of allows us the way to get around this particular problem: We can use pointers to get access to dynamically allocated memory, memory that is allocated as your program is running. It"s not allocated at compile time. When you dynamically allocate memory it comes from a pool of memory known as the heap. Previously all the memory we"ve been working with in the course has been coming from a pool of memory known as the stack. A good way to generally keep in mind is that any time you give a variable a name, it probably lives on the stack. And any time you don"t give a variable a name, which you can do with dynamic memory allocation, it lives on the heap. Now I"m kind of presenting this as if there"s these two pools of memory. this diagram is is generally a representation of what memory looks like, and we"re not going to care about all the stuff at the top and the bottom. What we care about is this part in the middle here, heap and stack . As you can see by looking at this diagram, these actually aren"t two separate pools of memory. It"s one shared pool of memory where you start, in this visual you start at the bottom and start filling up from the bottom with the stack, and you start at the top and start filling up from the top down with the heap. But it really is the same pool, it"s just different spots, different locations in memory that are being allocated. And you can run out of memory by either having the heap go all the way to the bottom, or have the stack go all the way to the top, or having the heap and the stack meet up against each other. All of those can be conditions that cause your program to run out of memory. So how do we get dynamically allocated memory in the first place? How does our program get memory as it"s running? Well C provides a function called malloc, memory allocator, which you make a call to, and you pass in how many bytes of memory that you want. So if your program is running and you want an integer runtime, you might mallock four bytes of memory, malloc parentheses four. mallock will go through looking through the heap, because we"re dynamically allocating memory, and it will return to you a pointer to that memory. It doesn"t give you that memory -- it doesn"t give it a name, it gives you a pointer to it. If mallock can"t give you any memory because you"ve run out, it"ll give you back a null pointer. We suffer a seg fault. So every time you make a call to malloc you always, always need to check whether or not the pointer it gave you back is null. If it is, you need to end your program because if you try and dereference the null pointer you"re going to suffer a segmentation fault and your program is going to crash anyway. So how do we statically obtain an integer? int x. We"ve probably done that a bunch of times, right? This creates a variable called x that lives on the stack . How do we dynamically obtain an integer? Int star px equals malloc 4. Or more appropriately we"d say int star px equals malloc size of int, just to throw some fewer magic numbers around our program. This is going to obtain for us four bytes of memory from the heap, and the pointer we get back to it is called px. And then just as we"ve done previously we can dereference px to access that memory. What if we want to create an array of x floats that live on the stack? float stack_array -- that"s the name of our array -- square brackets x. That will create for us an array of x floats that live on the stack. We can create an array of floats that lives on the heap, too. The syntax might look a little more cumbersome, but we can say float star heap_array equals malloc x times the size of the float. I need enough room to hold x floating point values. So say I need 100 floats, or 1,000 floats. So in that case it would be 400 bytes for 100 floats, or 4,000 bytes for 1,000 floats, because each float takes up four bytes of space. After doing this I can use the square bracket syntax on heap_array. Just as I would on stack_array, I can access its elements individually using heap_array zero, heap_array one. But recall the reason we can do that is because the name of an array in C is really a pointer to that array"s first element. So the fact that we"re declaring an array of floats on the stack here is actually a bit misleading. We really are in the second line of code there also creating a pointer to a chunk of memory that we then do some work with. Here"s the big problem with dynamically allocated memory though, and this is why it"s really important to develop some good habits when you"re working with it. Unlike statically declared memory, your memory is not automatically returned to the system when your function is done. So if we have main, and main calls a function f, when f finishes whatever it"s doing and returns control of the program back to main, all of the memory that f used is given back. It can be used again by some other program, or some other function that gets called later on in main. It can use that same memory over again. If you dynamically allocate memory though you have to explicitly tell the system that you"re done with it. It"ll hold onto it for you, which could lead to a problem of you running out of memory. And in fact we sometimes refer to this as a memory leak. And sometimes these memory leaks can actually be really devastating for system performance. How do we give memory back when we"re done with it? Well fortunately it"s a very easy way to do it. We just free it. There"s a function called free, it accepts a pointer to memory, So let"s say we"re in the middle of our program, we want to malloc 50 characters. We want to malloc an array that can capable of holding 50 characters. And when we get a pointer back to that, that pointer"s name is word. We do whatever we"re going to do with word, and then when we"re done we just free it. And now we have returned those 50 bytes of memory back to the system. So there are three golden rules that should be kept in mind whenever you"re dynamically allocating memory with malloc. So let"s go through an example here of what some dynamically allocated memory might look like mixed in with some static memory. So we say int m. What if I then say int star a? So I"m coloring it green-ish as well. I know it has something to do with an integer, but it"s not itself an integer. But it"s pretty much the same idea. I"ve created a box. Both of these right now live on the stack. I"ve given them both names. Then, int star b equals malloc size of int. Well this doesn"t just create one box. This actually creates two boxes. And it ties(连接在一起), it also establishes a point in a relationship. We"ve allocated one block of memory on the heap. Notice that the top right box there does not have a name. We mallocd it. It exists on the heap. But b has a name. It"s a pointer variable called b. That lives on the stack. So it"s a piece of memory that points to another one. b contains the address of that block of memory. It doesn"t have a name otherwise. But it points to it. Now we"ll get little more straightforward again. a equals ampersand m. Do you recall what a equals ampersand m is? Well that"s a gets m"s address. Or put more diagrammatically, a points to m. OK so here"s another one. A equals b. What"s going to happen to the diagram this time? Well recall that the assignment operator works by assigning the value on the right to the value on the left. So instead of a pointing to m, a now points to the same place that b points. a doesn"t point to b, a points where b points. If a pointed to b that would have been a equals ampersand(&) b. But instead a equals b just means that a and b are now pointing to the same address, because inside of b is just an address. And now inside of a is the same address. m equals 10, probably the most straightforward thing we"ve done in a little bit. Put the 10 in the box. Star b equals m plus 2, recall from our pointers video what star b means. We"re going to dereference b and put some value in that memory location. In this case 12. So when we dereference a point of recall we just travel down the arrow (遵循着箭头的轨迹). Or put another way, we go to that memory address and we manipulate it in some way. We put some value in there. In this case star b equals m plus 2 is just go to the variable pointed to by b, go to the memory pointed to by b, and put m plus 2 in there, 12. Now I free b. What happens when I free b? I"m done working with it, right? I essentially give up the memory. I give it back to the system. I don"t need this anymore is what I"m telling them, OK? Now if I say star a equals 11 you can probably already tell that something bad is going to happen here, right? And indeed if I tried that I probably would suffer a segmentation fault. Because now, although previously that chunk of memory was something that I had access to, at this point now I"m accessing memory that is not legal for me to access. And as we will probably recall, when we access memory that we"re not supposed to touch, that"s the most common cause of a segmentation fault. And so my program would crash if I tried to do this. 结语: So again it"s a good idea to get good practice and good habits ingrained when working with malloc and free, so that you don"t suffer segmentation faults, and that you use your dynamically allocated memory responsibly.

安装Discuz论坛时最后出现:Out of memory (allocated 16515072) (tried to allocate 1820 bytes),

我也不专业啊,建议你把文件上传到空间根目录上,联系空间商帮你安装。这样子 非常方便哦,我之前自己安装了老是不行,菜鸟做论坛,确实会有很多问题啊。多用百度搜索吧,另外修改前注意备份文件

未指定的错误(0x80004005:FAILED (remote:AlreadyAllocated))这个怎么解决

如果是直接更换的服务器,那么主机名更换了,以前存在数据库的主机名也需要删除。进入SQL2005查询器执行:select @@servernameEXEC sp_dropserver @@servernameEXEC sp_addserver [new_name], local第一行是查出老的实例名第二行是删除老的实例名第三行是 ‘new_name" 是新的实例名,也就是当前计算机名,在重启一下sql2005服务,执行完这一步,这时候如果asp会报错:Microsoft OLE DB Provider for ODBC Drivers 错误 "80004005"[Microsoft][ODBC SQL Server Driver][SQL Server]未将服务器 "anywolfs.com" 配置为用于 DATA ACCESS。 需要设置模式,执行:EXEC sp_serveroption "anywolfs.com", "data access", "true"这时如果asp遇到:[Microsoft][ODBC SQL Server Driver][SQL Server]此游标不包括正在修改的表,或该表不能通过此游标更新。则需要再重启sql2005,重启后还是没有解决问题,那么可以使用sp_helpserver 查看有多少实例名,然后统统都给他删掉(sp_dropserver @@服务器名 来删除所有服务器),在执行 sp_addserver 等其他操作。或者重新运行一下上面的命令,重新做一遍,重启sql2005解决不了问题可以重启服务器看看。我遇到的是错误3先查询出来再全都删除,在创建!

distribution与allocation的区别

呵以前我也会碰见类似的问题在分析词义时最好找英英字典或双解字典来分析,看一下例句,就知道了另外一个就是看词的词根,根据词根来区分单词的意思。distribution有分发的意思,是指分给每一个人的;也有分布的意思allocation 它的分发常常是指分配(任务,东西等),这个分配有一定的目的。

AIX DB2 使用db2start 命令 出错SQL1220N The database manager shared memory set cannot be allocated.

执行db2ftok,再db2start,试试。可能是/opt空间属性有问题,导致安装过程中不能产生.ftok文件

为什么Manufacturing Overhead 不计入work-in-process?

首先,M O/H 分为actual M O/H 和applied M O/H,在这里,后者就是你说的要allocated 的overhead,要和Direct Material (DM),Direct Labour(DL) 在一起,三个都要计入WIP。在这里applied M O/H可能要用到pre-determined overhead rate 和 hours 来算。x0dx0ax0dx0a其次,Actual manufacturing overhead 是后来算的,它包括IndirectMaterial (IDM),Indirect Labour (IDL) ,Others manufacture expenses。x0dx0ax0dx0a最后需要用actual M O/H和applied M O/H 比大小,如果Actual M O/H > Applied M O/H: Underapplied Overhead ,反过来是overapplied overhead. 差异应该计入COGS里。x0dx0ax0dx0a因为实际的overhead必须要整个生产过程都结束了才能知道,而wip必须是在生产过程中就要了解的,所以就需要applied M O/H,同时要记入wip里。但由于这只是估计的,所以最后要和实际的相比,差额要反应在减少,或者增加COGS的分录里,最后要反映在表里。
