workshop abstract
Peta- and exascale computing infrastructures make unprecedented demands on information storage capacity, performance, concurrency, reliability, availability, and manageability. This one-day workshop focuses on the data storage problems and emerging solutions found in peta- and exascale scientific computing environments, with special attention to issues in which community collaboration can be crucial, problem identification, workload capture, solution interoperability, standards with community buy-in, and shared tools. This workshop seeks contributions on relevant topics, including but not limited to: performance and benchmarking results and tools, failure tolerance problems and solutions, APIs for high performance features, parallel file systems, high bandwidth storage architectures, wide area file systems, metadata intensive workloads, autonomics for HPC storage, virtualization for storage systems, archival storage advances, resource management innovations.
All papers appear in the IEEE Digital Library.

Andree Jacobson, New Mexico Consortium Town Hall Meeting (resulting notes follow) - Attendees were happy to have a keynote; thought talk lengths were appropriate; were pleased with the web site, especially its simplicity. - Requests for the future include printed agendas available to attendees, draw in IO-intensive users to workshop, possibly through keynote, update SC11 web site with PDSW11 agenda as it is available. - Specific to SC11 we should be involved in the SC11 theme on "Data Intensive Computing", perhaps with a Data Intensive theme ourselves, and with connections to the other theme events - With respect to the aging name "Petascale" we will relabel PDSW as Parallel Data Storage Workshop, so we can have the 6th PDSW at SC11. - We should note and track the plan for SC to become/join a SIG in ACM, IEEE or SIAM, so we can have an any-time-in-the-year sponsor, not just in November. |
