But the object requesting allocation space was also quite large.
但要求分配空间的对象也相当大。
In this paper, dynamical LMS algorithm and global optimization algorithm, with a view to gradient of error probability, are proposed based on analysis of sub-carries allocation space for OFDM system.
通过对OFDM的子信道比特分配空间进行分析,本文提出着眼于误比特概率梯度的动态lms算法和全局优化算法。
All UNIX systems usually have one allocation of primary swap space.
所有unix系统通常都有一个主交换空间分配。
If your policy is early page space allocation, it will not kill the process.
如果您的策略是早页面空间分配策略,它将不会终止进程。
In this section, I provide an overview of how AIX handles paging, define swapping and paging, and drill down into the different modes of paging space allocation.
在这个部分中,我介绍了AIX如何处理分页,给出了交换和分页的定义,并深入地研究了分页空间分配的几种不同模式。
It does this by using a process called early allocation of paging space, by partitioning segments into pages.
使用一个称为分页空间预分配的过程,通过将段划分为页面,可以完成这项任务。
This feature is available only when using the deferred page space allocation policy.
仅在使用延迟页面空间分配策略时,才能使用这种特性。
The default policy of AIX is deferred page space allocation.
AIX的缺省策略是延迟的页面空间分配。
Memory and paging space allocation by default is late.
在默认情况下,内存和分页空间采用晚分配。
To add the swap space permanently to your system, you must configure one of the boot configuration files to enable the swap allocation automatically.
若要永久地将交换空间添加到系统,您必须配置启动配置文件之一来自动启用交换空间分配。
This feature is only available for the default deferred page space allocation policy.
这种特性只能用于缺省的延迟页面空间分配策略。
Before assigning extra paging space to your system, it's worth looking at memory allocation and memory tuning.
为系统分配额外的分页空间之前,检查内存分配和内存调优是值得的。
Garbage collection works in a number of configurable ways through the deferred page space allocation policy.
可以通过延迟的分页空间分配策略以多种可配置的方式执行垃圾收集。
Late paging space allocation causes paging disk blocks not to be allocated until its corresponding pages in RAM are touched.
晚分页空间分配策略会直到RAM中的页面被修改时才分配相应的分页磁盘块。
The default policy of AIX 7 is deferred page space allocation.
AIX7的默认策略是延迟的分页空间分配。
AIX 7 provides three different modes of paging space allocation: deferred page space allocation, late page space allocation, and early page space allocation.
AIX7提供三种不同的分页空间分配模式:延迟的分页空间分配、晚分页空间分配和早分页空间分配。
This activates the system to use the late paging space allocation policy.
这将让系统使用晚分页空间分配策略。
If the amount of free space available in the small object area is much greater than the size of the allocation request and yet the request can not be satisfied, the heap is fragmented.
如果小对象区域中的可用自由空间量远远大于分配请求大小,但是还无法满足请求,则表明堆中都是碎片。
This results in a "flat heap", where the entire heap space is available for transient object allocation rather than just the nursery space.
这将导致一个“扁平堆”,其中,整个堆空间(而不只是保育空间)都可用于临时对象分配。
What about early page space allocation?
那么早分页空间分配又如何呢?
If the allocation of parts of either memory or disk space have been exhausted before a calculation process is complete, your user will get an error message that memory or disk space has run out.
如果在计算处理完成之前,内存或磁盘空间的块分配已经耗尽,用户就会看到内存或磁盘空间用完的错误消息。
The trigger for a GC is usually an allocation failure - this occurs when the allocation of an object to the JVM heap fails due to insufficient available space.
GC的触发器通常是一个分配失败。分配失败是指,由于可用空间不足,无法将一个对象分配到jvm堆。
As new requests come in, memory allocation failures result, as GC kicks in pretty often to clear up space for the new requests.
当新的请求到来时,内存分配将会失败,通常使用GC来为新的请求腾出空间。
Let's view how AIX 7 is currently handling paging space allocation (see Listing 2).
让我们来看看AIX7当前如何处理分页空间分配(见清单2)。
The aim of the GC is to clear up the JVM heap of any objects that are no longer required, thus providing enough space for the object that previously failed allocation.
GC的目标是清理不再需要的对象的JVM堆,从而向此前分配失败的对象提供足够的空间。
Let's view how AIX is currently handling paging space allocation (see Listing 2).
让我们来看看AIX是如何处理分页空间分配的(请参见清单2)。
This works by making sure that the allocation of paging space is delayed until the time that it is necessary to page out the page, which ensures that there is no wasted paging space.
这确保将分页空间的分配延迟到必须调出页面的时候,从而确保不会浪费分页空间。
The creation of additional classes results in a 20 to 40 percent higher perm gen space allocation.
创建额外的类会导致多分配20%到40%的空间。
Allocation: in this phase, the container is given some sub-rectangle of pixel space and divides it among its children.
分配(allocation):在此阶段,为容器指定子矩形像素空间,并将其划分给它的child。
This entry lets us know that there was an allocation failure, which presents itself when there is not enough contiguous space in the heap to allocate the object.
通过这个条目,我们能够知道有一个分配失败,当heap内没有足够的连续空间可以分配给对象时,就会发生分配失败。
