Collection types for database programming in the BSP model
نویسندگان
چکیده
We study the pragmatics of integrating collection types, that model a broad class of non-numerical applications, into the Bulk Synchronous Parallel (BSP) model which abstracts a diversity of parallel architectures using just four numerical parameters. We outline how the collection types have been built on-top of the direct BSP programming environment provided by BSPlib, give results on a SGI PowerChallenge and IBM SP2, and discuss how these types can help implement object databases.

Towards a Scalable Parallel Object Database { The Bulk Synchronous Parallel ApproachK
Parallel computers have been successfully deployed in many scienti c and numerical application areas, although their use in non-numerical and database applications has been scarce. In this report, we rst survey the architectural advancements beginning to make general-purpose parallel computing cost-e ective, the requirements for non-numerical (or symbolic) applications, and the previous attempt...
