St.Petersburg state university computing centre and the 1st results in the DC for ALICE V.Bychkov, G.Feofilov, Yu.Galyuck, A.Zarochensev, V.I.Zolotarev St.Petersburg State University, Russia Contents SPbSU computing and communication center in Petrodvorets (structure, capabilities, communications, general activity). The progress obtained in summer 2004 in St.Petersburg in DC for ALICE. Future plans Alice week off-line day

SPbSU Informational-computing center history Due to the historical reasons Saint Petersburg State University consists from 2 space- divided part. One of them located in the central part of the St. Petersburg. Other in the Petrodvorets – 40 kilometers from it. That’s why and also due to the fact that many other educational centers of the St. Petersburg are located in the central part, the optical channel from Petrodvorets to central part of St. Petersburg was created (during ).

Portal of the High Performance Computing (WEBWS)

SPbSU Informational-computing center. Portal of the High Performance Computing (WEBWS) WEBWS consists from 3 main part : 1. Informational part – monitoring of the computational resources based on Ganglia (open source software product), monitoring users tasks queries 2. Work space – users work space for development and starting tasks 3. Administrative part

Problems and questions Information on started jobs and running are not correlated? No correlation with our scripts for monitoring of started and running jobs? We will study these problems later.

Plans for Alice DC SPbSU is planning to continue DC2004 participation with resources: alice: 512 MB RAM, 40 GB., PIII 1x733 CPU alice09: 256 MB RAM,40 GB TB HDD, Celeron 1x1200 CPU Alice02-08: 1 GB RAM (4 GB swap),PIII 2x600 CPU (two CPUs are used), 40 GB IDE HDD.
