Quarterly WP Report contribution from GridPP
For Section 1: “Technical achievement ”
Please summarise below all work done by “GridPP” staff during this quarter. Also
describe any “ issues” which have arisen.
T. Barrass (Bristol, 50% CMS WP8)
Continued to play a critical role in CMS production: after successfully coordinating the
development and use of a backbone scheduled data transfer scheme for CMS during
I s now working on the development of version 2, which will be in use by production by
the end of the summer to meet their goal of delivering 5 million events per month to PRS.
Based on this work Barrass is the principal author on one and named author on several
other CHEP 2004 papers this year.
B. MacEvoy (Imperial College, 50% CMS WP8)
Barry MacEvoy has been working the GROSS analysis framework which
has now been released and is being tested by the Italians, the Americans
and the Taiwanese. This project is documented at
Barry has also started to look at the web services architecture employed
by the American Grid Analysis Environment (GAE) which is going to provide
a significant contribution to the CMS/ARDA. He is determining how this can
be integrated with GROSS.
Barry has also maintained the LCG nodes (for CMS use) and maintains the
Imperial e-Science web pages.
O. Maroney (Bristol, 50% CMS WP8)
Owen left Bristol at the end of March 2004 to take up a new position at Imperial College
London (London T2 Technical Manager)
J. J. Nebrensky (Brunel, 50% CMS WP8 + 30% HEFCE contribution)
NOTE: Dr Nebrensky’s time is allocated at an average of 80% to GRIDPP. However
this reporting quarter coincides with his heaviest teaching and marking load so that
his actual contribution of time to GRIDPP was approximately 50% of an FTE.
Work on generating user requirements for Task 3.4.9
Made corrections and significant additions to the IEEE paper as requested by the referees
Is working on getting our LCG2 test cluster operational so that we can continue to
evaluate the performance of RGMA and BOSS with real production jobs.
Attended the WILGA symposium in Poland (CMS, Grid computing and Optics).
H. Tallini (Imperial College, 100% CMS WP8)
Tallini has been working the GROSS analysis framework which has now been released
and is being tested by the Italians, the Americans and the Taiwanese.
Hugh Tallini left Imperial College for a job outside of HEP at the end of May 2004.
