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.
