The protein folding problem is a fundamental problem in computational molecular biology and biochemical physics. The high resolution 3D structure of a protein is the key to the understanding and manipulating of its biochemical and cellular functions. All information necessary to fold a protein to its native structure is contained in its amino-acid sequence.(More)
It has been suggested that utilization of autonomous software agents in computational Grids may deliver the needed functionality to speed-up Grid adoption. I our recent work we have outlined an approach in which agent teams facilitate Grid resource brokering and management. One of the interesting questions is how to manage trust in such a system. The aim of(More)
Recently, we can observe an increasing interest in utilization of software agents in computational Grids. In our work agent teams play role of Grid resource brokers and managers. Previously we have discussed how to efficiently implement matchmaking services, as well as proposed a way by which agents select a team that will execute their job. In this paper(More)
Recently we have proposed an approach to utilizing agent teams as resource brokers and managers in the Grid. Thus far we have discussed the general overview of the proposed system, how to efficiently implement matchmaking services, as well as proposed a way by which agents select a team that will execute their job. In this paper we focus our attention on(More)
The recently introduced circulant block{factorization preconditioners are studied. The general approach is rst formulated for the case of block tridi-agonal sparse matrices. Then an estimate of the relative condition number for a model anisotropic Dirichlet boundary value problem is derived in the form < p 2"(n + 1) + 2, where N = n 2 is the size of the(More)
