We investigate the efficient iterative solution of large-scale sparse linear systems on shared-memory multiprocessors. Our parallel approach is based on a multilevel ILU precondit...
For complex queries in parallel database systems, substantial amounts of data must be redistributed between operators executed on different processing nodes. Frequently, such inter...
Checkpointing and rollback recovery is a very effective technique to tolerate transient faults and preventive shutdowns. In the past, most of the checkpointing schemes published i...
Prototype databases are needed in any information system development process to support data-intensive applications development. It is common practice to populate these databases u...
