Multicomputer object stores: the Multicomputer Texas experiment

The paper is about design of object stores for distributed memory computers. Problems of distribution within such stores areThis paper appeared in the proceedings of the Seventh International Workshop on Persistent Object Systems described through the design of Multicomputer Texas, a system derived from the Texas store [8] and implemented on a scalable multicomputer (a Fujitsu AP1000). Problems discussed include creating a single image of an object space across multicomputer architectures, tradeoffs between page-based and object-based granularity, the distribution of store level services and the management of concurrency and persistance within those distributed services. Problems of building layered software on multicomputers pervade these issues. Preliminary scalability performance figures for Multicomputer Texas are also presented.
