So, why exactly does XFS have allocation groups?
那么，XFS到底为什么要有分配组呢？
Primarily, XFS USES allocation groups so that it can efficiently handle parallel IO.
主要原因是，XFS使用分配组，以便能有效地处理并行io。
As you'll recall from my previous article, allocation groups let XFS perform multiple metadata operations in parallel.
正如您将从我前一篇文章所回忆的一样，分配组让XFS并行执行多个元数据操作。
So rather than let mkfs.xfs choose the number of allocation groups for your filesystem, specify a number by using the -d agcount=x option.
因此，不要让mkfs.xfs为您的文件系统选择分配组的数目，而是通过使用 -d agcount=x 选项指定一个数目。
The second option lets you enhance the performance of your new filesystem by telling mkfs.xfs to minimize the number of allocation groups that are created.
第二个选项通过告诉mkfs.xfs 将创建的分配组的数目最小化，让您增强新文件系统的性能。
Allocation groups also help to optimize parallel IO performance on multiprocessor systems, because more than one metadata update can be "in transit" at the same time.
分配组还有助于在多处理器系统上优化并行io性能，因为可以同时有多个元数据更新处于“在传输中”。
Thanks to allocation groups, the XFS code will allow multiple threads and processes to continue to run in parallel, even if many of them are performing non-trivial IO on the same filesystem.
多亏了分配组，XFS代码将允许多个线程和进程持续以并行方式运行，即使它们中的许多线程和进程正在同一文件系统上执行大规模IO 操作。
The allocation of sub groups then to controllers such as light switches, mains sockets and similar is then done from each pool.
这之后每一个单元的地址池会将子网地址分配到每一个控制器，比如电灯开关，插销座等等。
Each allocation group allocates inodes as needed, in groups of 64.
每个分配组在需要时以64个索引节点为一组来分配它们。
Server Groups are important because they define the scope for load balancing and service allocation in general.
ServerGroups很重要，因为它们通常定义负载平衡和服务分配的范围。
Trials eligible for inclusion are classified according to the reader's degree of certainty that random allocation was used to form the comparison groups in the trial.
对于使用随机分配设立对照组的入选试验，其具体分类取决于读者对试验报告的把握。
A barycenter model of group decision making on resource allocation is constructed in this paper using groups loss function based on the additive kind of group cardinal utility function.
根据群体基数效用函数的加和性，用距离表示群体的损失函数，建立了资源分配群体决策的重心模型。
Product input and output voltage level is based on, join groups, adjust the number of taps, winding single-phase capacity allocation, and secondary windings, the use of purification circuit.
产品输入，输出的电压高低是根据，联接组别，调节抽头多少，绕组容量分配以及次级单相绕组，净化电路的运用。
Of course, in any country, there are times when we do accord preferential treatments to certain groups of society in order to achieve the optimum allocation of resources.
当然，在任何一个国家，在有些时候，人们确实会赋予某些社会群体以优先的待遇，以便实现资源的最佳配置。
This is exactly why experiments using random allocation to groups are so useful for psychologists.
这就是为什么试验使用随机的分配对心理学家如此有益。
Methods Divide 74 platelet-reduced acute leukemia patients into two groups with randomized allocation. Therapy group transfuses platelet with UBIO, and control group only transfuses platelet.
将74例血小板减少的急性白血病患者随机分为两组，治疗组采用血液光量子疗法进行血小板输注，对照组单纯行血小板输注。
