The problem of access control across multiple security domains in data sharing environment is addressed and a rule-based algorithm for role mapping across multi-domains is presented. The algorithm resolves efficiently the conflicts of cyclic inheritance and separation of duties, and the problem of regression inheritance. The algorithm takes the “Least privilege theorem” into account and prohibits accesses from illegal domains. Further more, the algorithm makes the establishment of role mapping across multi-domains more efficiently by preserving historical information of role mapping paths established successfully before, and satisfies preferably the access control requirement across dynamic multi-domains in data sharing environment. Evaluation by access instances shows the efficiency of our algorithm.

Complicated global climate problems trigger researchers from different scientific disciplines to link multiphysics simulations called models for integrated modeling of climate changes by using a software framework called earth system modeling (ESM). As its critical component, coupler is in charge of connections and interactions among models. With the advance of next-generation models, greater data transfer volume and higher coupling frequency are expected to put heavy performance burden on coupler. High efficient coupling techniques are required. In this paper, we propose the sub-domain mapping method to improve the parallel coupling consisted of data transfer and data transformation. By using one specific interpolation oriented communication routing, the communication operations that are originally decentralized in various steps can be combined together for execution. This can reduce the redundant communications and the entailed synchronization costs. The tests on the Tianhe-lA (TH-1A) supercomputer show that our method can achieve 1.1 to 4.9 fold performance improve- ments. We also present further optimization solution for the multi-interpolation cases. The test results show that our method can achieve up to 3.4 fold speedup over the original coupling execution of the current climate system.
