A practical problem faced by users of metacomputers and computational grids is: If my computation can move from one system to another, how can I ensure that my data will still be ...
Existing Grid workflow tools assume that individual components either communicate by passing files from one application to another, or are explicitly linked using interprocess com...
Noncontiguous data access is a very common access pattern in many scientific applications. Using POSIX I/O to access many pieces of noncontiguous data segments will generate a lot...
Replication is a technique used in Data Grid environments that helps to reduce access latency and network bandwidth utilization. Replication also increases data availability thereb...
External sorting--the process of sorting a file that is too large to fit into the computer's internal memory and must be stored externally on disks--is a fundamental subroutin...
