This document outlines updates on grid computing resources across the Netherlands (NLGrid), Belgium (BEGrid), and Sweden (SweGrid). NLGrid is expanding with additional Xeon CPUs and storage solutions for multiple virtual organizations, while BEGrid currently runs six LCG2 sites. SweGrid includes various CPU clusters and preparations for new systems. The report also addresses some challenges in communication and local support centralization. A collaborative approach among these grids aims to enhance performance and resource sharing for scientific research.

Presentation Transcript

  1. NE Resources (1) • Netherlands (NLGrid) – two sites • 366 WN CPUs • 2 disk SEs: 7 TB, mass storage SE: 20TB tape • 2 RBs, RLS and VO LDAP servers for NL-Grid and EGEE • VO support • National: NCF, PVIER, ASTRON, Nadc, VLe, Asci • EGEE: ALICE, ATLAS, LHCb, CMS, Dzero, ESR, Magic • Cluster with 544 Xeon™ CPUs may become CE (with Debian OS) later this year • Belgium (BEGrid) • 6 sites running LCG2 software, not integrated in EGEE yet SA1 ARM meeting 17-18 March, Lyon

  2. NE Resources (2) • Sweden (SNIC/SWEGRID) Three sites • HPC2N • 100 CPU cluster • LCG2.3, SLC CE, Debian WN • SE 10 TB • Worker nodes are shared between EGEE and SweGrid (ARC) • PDC • Installation in preparation of a 100 CPU system • Eventually new 884 CPU Xeon EM64T cluster (in stable gLite time) • NSC • 32 CPU cluster on pre-production testbed • SLC all over • LCG23 • Other stuff ( GGAS (Grid bank), SWEGRID VO Management tool) • Finish RC earliest April • VO support • National: Atlas, NorduGrid (used for individual scientists using SweGrid) • To be transferred to EGEE SA1 ARM meeting 17-18 March, Lyon

  3. NE Issues • Many answers can be found (for LCG) in the LCG-ROLLOUT archives • can we consolidate? • Accounting: we need filters to extract VO specific information • CIC on Duty – communication sometimes difficult • No response to questions/remarks • Local support not yet centralized SA1 ARM meeting 17-18 March, Lyon
