M.S. Paper: IBL for replica selection in data intensive Grid
applications
Abstract:
In many scientific applications, Grid technologies and infrastructures
facilitate distributed resource sharing and coordination in dynamic,
heterogeneous multi-institutional environments. Replication of date
can help enable high throughput file transfer and scalable resource
storage in these scientific Grid applications that involve large data
transfers. However, the selection of a replica can significantly
influence the efficiency of a replication scheme. Many current
approaches assume that a significant amount of data is available, such
as network status information, log files of historical GridFtp file
transfers, CPU status and predictions, etc. We propose a lightweight
Instance-Based Learning (IBL) algorithm to allow efficient replica
selection with much less required data. We implement the approach and
evaluate it in a Grid environment. Our evaluation demonstrates that
the IBL approach can be an efficient tool for replica selection when
only limited data sources are available.
Mr. Hu's advisors: Ian Foster and L. Ridgway Scott
A draft copy of the M.S. paper is available for review in Ry 161A.
