Bldg. 66 Auditorium (Lawrence Berkeley National Laboratory)

Storage II

Speaker

Peter van der Reest (DESY)

Description

At DESY we have installed a testbed for Grid and storage related issues. One of the first trials we did was running a ALICE Proof job against data held in a distributed NFS 4.1 service based on dCache. Also trails were made against an industrial system, of which I am not allowed to speak yet. Comparisons we made with regard to scaling in PROOF and IO performance in comparison to NFS3 To make it more savvy, we have an accompanying movie which shows the running computation and the IO received.
