This paper introduces a new HPDC resource management paradigm named resource slot which defines a network of logical machines across time and space. A resource slot is not only a resource programming target but also a virtu-alized resource provisioning framework for a variety of resource management paradigms by encapsulating the resource management complexity. Especially, we present a resource provisioning technique named guided redun-dant submission (GRS), which probabilistically guaran-tees a timely resource slot allocation. Experimental re-sults performed against 8 clusters in production show that about 5 redundant resources per slot can secure slot allo-cation with up to 36 logical machines, each cluster having an availability probability as low as 0.25 and the target success probability of slot allocation is 0.95.

This paper introduces a technique called personal cluster which reserves a partition of batch resources on user’s demand in a best-effort manner. A personal cluster provides a private cluster dedicated to the user during a user-specified time period by installing a user-level resource manager on the resource partition. This technique not only enables cost-effective resource utilization and efficient task management but also provides the user a uniform interface to heterogeneous resources regardless of local resource management software. A prototype implementation using a PBS batch resource manager and Globus Toolkits based on Web Services shows that the overhead of instantiating a personal cluster of medium size is small, which is just about 1 minute for a personal cluster having 32 processors.

We addresses these problems by creating a higher level resource abstraction that layers on top of existing Cyberinfrastructure that allows an application to target stable resource aggregations spanning sites through a well - defined and standard - compatible interfaces . The functionality of vgES automatically maps application centric Virtual Grid specifications onto available resources through a split - phase provisioning and actualization protocol . Clients of vgES see all resources in terms of single resource slot abstraction that can be treated as a form of advanced resource reservation even when underlying resource do not support such reservations directly .
