The architecture of an innovative portal based on a fine-grain modularity and an assembly technology is presented. The portal resources and services for the interaction between participants of the innovative activity within a common information space are realized. The investigation of the system and the creation of its prototype have shown that the informational, computational, and communication capabilities of the network infrastructure should be increased. The scalability of the portal calls for its installation in the network of Supercomputer Centers, RAS is based on the GRID technology. The implementation of such a scheme would make it possible to carry out complicated innovative projects by using the entire set of supercomputers.
