Abstract
We describe a prototypical storage service through which we are
addressing some of the open storage issues in
wide-area distributed high-performance computing. We discuss some of
these issues, such as latency-tolerance,
heterogeneity, adaptive communications and storage utilisation, tertiary
storage integration, and support for legacy and
commercial applications. Existing systems addressing these issues in
high-performance computing environments are
either ad-hoc or focus narrowly on the simple client-server case. The
storage service which we are developing as part
of the DISCWorld metacomputing infrastructure will provide
high-performance access to a global ``cloud'' of storage
resources in a manner which is scalable, secure, adaptive, and portable,
requiring no application or operating system
modifications. Our system design is such that it provides flexible,
modular and user-extensible access to arbitrary
storage mechanisms, and on-demand data generation and transformations.
We describe our current prototype's status,
other related research and our future plans for the system.
