DPC Conclusion Grid technology Rationalize Processing Resources (Structured Processing Bus) Enhances Flexibility Use of remote resources with minimal effort Partly automated integration of new processing resources New Functionality Preemption for high priority requests Still to solve (DPCO) avoid transferring input data over the WAN if input availablealso in the remote MMFI archive avoid transferring back results to distribute to users, whilecapacity for distribution is also available in the remotecentre
