The MDS Queue: Analysing Latency Performance of Codes and Redundant Requests
In order to scale economically, data centers are increasingly evolving their data storage methods from the use of simple data replication to the use of more powerful erasure codes, which provide the same level of reliability as replication-based methods at a significantly lower storage cost. In particular, it is well known that MaximumDistance-Separable (MDS) codes, such as Reed-Solomon codes, ...
متن کاملWhen Do More Patents Reduce R&D?
This paper develops a simple duopoly model in which investments in R&D and patents are inputs in the production of firm rents. Patents are necessary to appropriate the returns to the firm’s own R&D, but patents also create potential claims against the rents of rival firms. Analysis of the model reveals a general necessary condition for the existence of a positive correlation between the firm’s ...
متن کاملThesis Proposal: Analyzing Systems with Redundant Requests
Reducing response time is a primary focus of computer systems research. One key factor that influences a job’s response time in a multi-server system is dispatching: when a job arrives to the system, it must be sent immediately to one of the servers. This thesis focuses on a new dispatching policy: redundancy. Unlike traditional dispatching policies, which send only a single copy of each job, t...
متن کاملQueueing with redundant requests: exact analysis
Recent computer systems research has proposed using redundant requests to reduce latency. The idea is to run a request on multiple servers and wait for the first completion (discarding all remaining copies of the request). However, there is no exact analysis of systems with redundancy. This paper presents the first exact analysis of systems with redundancy. We allow for any number of classes of...
متن کاملWhen right is redundant.
Clinicians frequently see the “right middle lobe” referred to in radiology reports, textbooks, and medical journals. Yet, there is no “left” middle lobe to distinguish it from, save a rare patient with Kartagener syndrome. We do not refer to the lingula as the “left” lingula. “Right” adds nothing to our understanding of the anatomic position of the lobe. So “right” is redundant when talking abo...
