Abstract:
—In this paper, we consider the problem of data sharing
in scientific workflows running on the cloud. We present the
design and evaluation of a peer-to-peer approach to help solve
this problem. We compare the performance of our peer-to-peer
file manager with that of two network file systems for storing
data for a typical data-intensive workflow application. Our
results show that while our peer-to-peer file manager performs
significantly better than one of the network file systems tested, it
does not perform as well as the other. Finally, we discuss the
various issues that might have affected the performance of our
peer-to-peer file manager.
