CERN openlab Phase I - opencluster

Grid Computing: LCG on Itanium

In collaboration with the LCG team we are porting the software used for the LHC Computing Grid Project (LCG) to Itanium® 2 processsors. This includes middleware from EDG, EGEE, a special patched version of Globus (VDT distribution) and some additional software. The rpms are made publicly available.

Availability

The current tag available is LCG-2_7_0. The software has been tested on Scientific Linux Cern SLC 3.

How to start

First decide which nodes you want to run on IA64. If you are already an LCG site using IA32s you might want to use the IA32 RB and UI. It is also possible to mix IA64 and IA32 nodes, e.g. an IA32 CE serving an IA64 cluster (WNs). However, the machines within one cluster of WNs should be homogeneous. For instructions on how to join LCG read the follwing document (html, pdf). Note that this document has been written only for IA32. For installation of IA64 nodes read the following section.

Installation and configuration

At the moment installation of the rpms must be done manually (or you invent your own procedure doing this). The apt mechanism is not supported. However configuration of the middleware can be done by YAIM. Please contact Andreas Unterkircher at CERN for any questions concerning LCG on IA64 installation.

The SPACI Project has developed automated installation procedures to install LCG on IA64. If you want to use them you can find instructions here.
