Long-term File Activity and Inter-Reference Patterns
نویسندگان
چکیده
We compare and contrast long-term file system activity for different Unix environments for periods of 120 to 280 days. Our focus is on finding common long-term activity trends and reference patterns. Our analysis shows that 90% of all files are not used after initial creation, those that are used are normally short-lived, and that if a file is not used in some manner the day after it is created, it will probably never be used. Additionally, we find approximately 1% of all files are used daily. This information allows us to more accurately predict the files which are never used. These files can be compressed or moved to tertiary storage enabling either more users per disk or larger user disk quotas.

Long - term File Activity and Inter - Reference Patterns ( CMG Paper # 2041 ) Lieutenant - Colonel Tim
As more files are stored on today’s computers, understanding file activity patterns becomes crucial for developing systems to either compress rarely used data, or store it on tertiary storage devices such as tapes and optical disks. In this paper we compare and contrast long-term file system activity between different types of computing environments. We examine three different Unix file system ...
متن کاملAncient Iranian Earthquakes: Chehr-Abad Salt Mine
Modern plate tectonic theory, the development of earthquake prediction and the mitigation of earthquake hazards are based on the study of earthquakes during the twentieth century. Investigation of earthquakes over a much longer period, although in no way invalidating the global importance of plate tectonics, shows that patterns of seismic activity do change with time and that areas of intense s...
متن کاملP6: Metabotropic Glutamate Receptor-Dependent Role in the Formation of Long-Term Potentiation
Long-term potentiation (LTP) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. The first clue of the potential role of glutamate receptors in LTP was in 1991 with the observation that the mGluR agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (ACPD), increased LTP. Studies have shown that ACPD induc...
متن کاملHighLight: a file system for tertiary storage
propose a name space metric that is the sum of the distances from each file to the closest common ancestor. For files in the same directory, this metric would be zero. For two files, one in a sub-directory of the directory containing the other, this metric would be one. Other metrics under consideration include "file ownership" (e.g., files owned by the same user) and "file accessors" (e.g., fi...
متن کاملPredicting File System Actions from Reference PatternsThomas
Most modern cache systems treat each access as an independent event. Events in a computer system, however are driven by programs. Thus, accesses occur in distinct sequences and are by no means random. The result is that modern caches ignore useful information. In a Unix le system, when the executable for the program make is referenced, it is likely that references to les such as cc, as, and ld ...
