The cost of the fellowship component of the collaboratory program is estimated at $1 million per year, an amount that would support 50 summer fellows per year at $20,000 each.

Regularly scheduled national symposia for testbed principal investigators, research staff, and graduate students, providing opportunities to share information, findings, and conclusions regarding the technical aspects of building, operating, and using collaboratories.

The objective of this recommendation is to foster the creation of a community of builders and users of collaboratory technology. It is envisioned that principal investigators, research staff, and graduate students working on the testbeds would attend these meetings to share experiences and the results of their work.

In conclusion, the committee believes that the program outlined by these recommendations is the appropriate level of effort that should be undertaken. Although it would be possible to carry out only the research component of the proposed program, the committee believes that the education component is a critical aspect of the effort. Without the education component, it is much less likely that a skilled and growing community of collaboratory users and developers will emerge. The two components taken together as a program constitute a strategic effort to improve the basic infrastructure supporting the conduct of computationally intensive science in the United States.



For example, the personnel budget of the National Center for Supercomputing Applications (NCSA) at the University of Illinois is about $6 million per year, of which about $5 million supports about 110 full-time senior people (personal communication with NCSA staff, January 15, 1993). Of these, about 50 full-time employees are involved in software development or scientific applications; the rest provide infrastructure support, consulting, documentation, and other user services. The nonsalary component of NCSA's funding is devoted primarily to equipment purchase or lease and maintenance, including staff, infrastructure, and support costs. The major funding for the Human Genome Project is a grant from NIH and DOE for $6 million per year, which provides support for about 50 full-time senior people, who are primarily at the main site at Johns Hopkins University, plus coordination of the many other consultants and contractors (personal communication with John Wooley, DOE).
