12/01/2009: The University of Liverpool GridPP's Tier2 cluster is now available to NGS users.
Introduction
The Liverpool GridPP NGS Affiliate resource is provided by the Liverpool University High Energy Physics group. The resource utilises the GridPP Tier2 cluster (known as MAP2), which is used primarily by LHC physics experiments for simulations and data analysis via the EGEE/LCG grid.
System Configuration
The University of Liverpool GridPP's Tier2 cluster currently has 650 cores [Dell PowerEdge 650, 3GHz Pentium4 processors, i386] and a total of 150 Terabytes of storage space. Each node has 1GB of main memory per core. The cluster runs the Scientific Linux 4.4 operating system.
Users' home directories are local to each worker node where their jobs run. There is 55GB of temporary space available to each job in the /home area.
Our current hardware does not support parallel jobs. Jobs cannot be submitted to the site with a maximum duration longer than 72 hours.
More information about the hardware configuration can be found here.
Middleware, compilers and other software
The gLite 3.1 Grid Middleware is installed. Based on Globus Toolkit 2, gLite affords the usual NGS facilities for job management and file transfer. The usual suite of GCC compilers, JDK etc are provided by the base Scientific Linux 4 operating system (based on RedHat Enterprise Linux 4).
Direct user interface is only available to local users. Jobs can be submitted externally via resource brokers. The computing element (CE) host is hepgrid2.ph.liv.ac.uk and the contact string for the NGS queue is
hepgrid2.ph.liv.ac.uk:2119/jobmanager-lcgpbs-ngs
Contact
Any queries regarding the NGS at the University of Liverpool GridPP should be submitted by email to the NGS support desk: support@grid-support.ac.uk
