Another Examplefor Computing Cluster • University at Stony Brook, Departnet of Chemistry, Laboratory of Nulear Chemistry • DEC Alpha 4100 (500 MHz). • 32 machines (dual PIII/500, 256 MB); • Tape Robot for 3 TB; • RAID array 1.5 TB. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI
Problems • Security • against attacks from Internet and Intranet; • against unplanned data losses; • To keep up to date the software base on whole cluster. • To save network bandwidth by keeping locally the special cache for experimental data. • Appropriate Batch System. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI
Possible Plan for Small Physics Laboratory • To install the hardware: (3-5) PCs (about 0.8-1.3 GHz, 0.5GB of main memory, DLT stacker on the base DLT-8000, Switch with 1 Gbit uplink, etc., etc.). • To install the software: Linux, CERNlib, Objectivity/DB, GLOBUS, etc., etc. • To prepare and test logical connectivity to CERN and to Regional Computing Facility for LHC. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI
Conclusion • Relatively new situation for many small and midrange laboratories (like PNPI): • Main direction in HEP computing at PNPI is to create good front-end for High Performance Computing Facilities plus MSS outside Institute. • We have to collect all the available financial, technical, administrative resources and plan to work in close collaboration.
