ÂASIC PRINCIPLES OF LOOKAHEAD SCHEDULING METHOD FOR COMPUTATIONAL GRID
One of the most important program technologies that forms the base of globally distributed computer infrastructure — grid, is resource virtualization. In this paper we propose a new method of virtualization called Lookahead scheduling. The characteristic feature of the method is its ability to build up in advance a plan of resource allocations. Such ”predictive” scheduling even in the conditions of shared resources has a property of the determinacy — realization of the plan is provided by means of advance reservation. The determinacy makes Lookahead method suitable for a multiple-processor job management.

PEDAGOGICAL REQUIREMENTS FOR CAD/CAM EDUCATIONAL PROGRAMME
In the paper the results of examination the CAD/CAM dependency on system properties and the efficiency of geometrical engineering education of students at technical institutes of higher education are presented. The requirements are given for refining teaching and ergonomic characteristics of training programs. The obtained results are implemented in educational process at the “Aircraft Engines” department of Samara State Aerospace University.
