项目摘要
The cost of writing data from a computer's processor to its storage components remains a bottleneck for modern computing systems. The speed of the processor continues to improve, more processing units are packed into a computer chip, but these advances only cause more data to be written to storage per second. The speed of storage subsystems has not kept pace with the processor?s ability to produce data for storage, and this difference in performance is likely to continue. Moreover, the trend in building storage subsystems for computers is to utilize technologies such as flash memories whose contents can be changed a relatively small number of times before the memory wears out. These technologies are cheaper and pack more storage into a given area, but care must be taken to avoid writing to memories made from such technologies at rates usually seen from a processor to memory.This EAGER project aims to discover mechanisms that reduce or eliminate traffic from a processor to the storage subsystem. Elimination of such traffic increases the speed of the overall system and saves wear on storage components. This research finds data that would otherwise be sent to storage from the processor and eliminates such writes to memory. This technique is based on finding that such data cannot subsequently be referenced by an application. This effort focuses on a preliminary study to validate the technical approach, namely investigating the consequences of eliminating stores of data that has been explicitly deallocated by an application.
将数据从计算机处理器写入其存储组件的成本仍然是现代计算系统的瓶颈。处理器的速度不断提高,更多的处理单元被装入计算机芯片中,但这些进步只会导致每秒向存储器写入更多的数据。存储子系统的速度没有跟上处理器的速度吗?产生存储数据的能力,而且这种性能上的差异很可能会持续下去。此外,计算机存储子系统的建设趋势是利用闪存等技术,这些技术可以在内存磨损之前相对较少地更改内容。这些技术更便宜,并且在给定的区域内封装了更多的存储空间,但是必须小心避免以通常从处理器到存储器的速度写入由这些技术制成的存储器。这个EAGER项目旨在发现减少或消除从处理器到存储子系统的流量的机制。消除这种流量可以提高整个系统的速度,并节省存储组件的磨损。这项研究发现了原本会从处理器发送到存储的数据,并消除了对内存的写入。该技术的基础是发现这些数据随后不能被应用程序引用。这项工作的重点是验证技术方法的初步研究,即调查消除已被应用程序显式释放的数据存储的后果。
