The Role of the Project in CMS
CMS Event Rates and Data Sizes
Event input rate from event store 102 HZ
Data input rate from event store 100 MB/s
CPU capacity required to reconstruct one event 2 X 104 MIPS-s
Reconstructed data per event 0.1 MB
Reconstructed data output rate to event store 10 MB/s
Raw and reconstructed data few PB/year
CPU capacity required for physics analysis ~8 X 106 MIPS
Total CPU capacity for reconstruction and analysis ~107 MIPS
Total LHC data after ~5 years ~50 PB
The Project is not meant to be specific to one experiment: it’s goals are generic to ALICE, ATLAS, CMS and LHC-B
However, there is strong focus on the immediate needs of CMS in the areas of:
- The work areas described in the CMS Computing Technical Proposal
- The H2 Test Beam OO prototype
- WAN connectivity
Caltech is a CMS collaborating institute and is the host institute for the project
The SPP Exemplar 2000 is installed at Caltech’s Centre for Advanced Computing Research (CACR)
