2nd Parallel Data Storage Workshopheld in conjunction with
|
workshop abstract
Petascale computing infrastructures make petascale demands on information storage capacity, performance, concurrency, reliability, availability, and manageability. The last decade has shown that parallel file systems can barely keep pace with high performance computing along these dimensions; this poses a critical challenge when near-future petascale requirements are considered. This recurring one-day workshop focuses on the data storage problems and emerging solutions found in petascale 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.
