在虚拟化的所有层次和所有方向上的努力造就了相关的软件,它们能够让科学走在人为约束(在许多计算环境中是很常见的)的前面。
Diligence in virtualization at all levels and in all directions has resulted in software that puts science before the artificial constraints common in many computing environments.
通过从这一约束条件划分子类, RelevantResource 类成为一种包含一个所有满足该约束条件资源集合的虚拟类。
By its subclassing from this restriction, the RelevantResource class is a sort of virtual class that includes a set of all resources that meet the restriction.
虚拟化还能隐藏物理约束,从而更轻松地最小化物理资源更改的影响。
It hides physical constraints, which makes it easier to minimize the impact of changes to physical resources.
