Grid and SCIEnce Semeniouk Igor LLR, Ecole Polytechnique Atelier de projet I3 SCIEnce

10 Jan 2007Atelier de projet I3 SCIEnce Semeniouk Igor, LLR1 Why Grid Early Grid pioneers found that too hard to keep track of authentication data (ID/password) across institutions too hard to monitor system and application status across institutions too easy to leave "dangling" resources lying around, reducing system robustness too many ways to submit jobs too many ways to store, access, and ultimately manage distributed data.
