  3. The problem System administrators and managers of terascale computer centers are facing a crisis: • Computer centers use incompatible,ad hoc sets of systems tools. • Present tools are not designed to scaleto multiteraflop systems – tools must be rewritten. • Commercial solutions are not happening because business forces drive industry toward servers, not high-performance computing.

  4. 10110001 11001100 00100101 Scope of the effort Accounting and usermanagement Allocationmanagement Resourceand queue management Faulttolerance Checkpoint/restart Security Systembuild and configure System monitoring Jobmanagement Improve productivity of both users and system administrators

  5. Reduced facilitymanagement costs More effective use of machines by scientific applications Fundamentally change the way future high-endsystems software is developed and distributed Impact • Scalable launch of jobsand checkpoint/restart • Job monitoring and management tools • Allocation management interface • Reduce duplication of effort in rewriting components • Reduce need to supportad hoc software • Better systems tools available • Able to get machines up and running faster and keep running • Especially important for LCF
