In Brief: TRECC Tackles On-Demand Computing

Technical project lead Greg Koenig says TRECC 's approach to secure cluster computing on demand is a matter of managing workflow. "If a lower-priority job is consuming resources when a higher-priority job comes along, the scheduler must have enough information to determine whether it can fulfill the higher priority job's requirements, such as a deadline, with the remaining available resources," Koenig says. "If this cannot happen, then some mechanism must exist for clearing the resources for the higher-priority job."
