SGC upgrade and future: for CMSHI program

1
SGC upgrade and futurefor CMS-HI program

• Inkyu Park (Univ. of Seoul)
• for Korean CMS-HI team

2
OSG (Open Science Grid)

• OSG is a distributed computing infrastructure for
  scientific research
• Consortium of universities, national lab,
  computing industries.
• Contribute and share resources benefit
• Supported by NSF and DoE
• www.opensciencegrid.org

OSG for CMS-HI

• CMS-HI is mainly supported by US-CMS
• US-CMS supports OSG (Open Science Grid)
• UoS will participate both OSG and LCG
• Seoul Grid Center (supported by Seoul city) will
  support CMS-HI activity as data-grid, and CPU
  farm (3M facility 0.2M/year)
• KR CMS-HI 4 institutions (10 people)
• Jet finder library for CMSSW, HI MC production,
  Elliptic flow Forward physics.

If any CMS TIER exists, we want to be connected
as a sub-system!

Korean CMS-HI contribution

• SGC ? data-grid, CPU farms
• 128 machines ? maximum of 128TB storage
• 128 CPU cluster ? MC generation farm
• 64 new dual core dual process machines are
  added ? UOSPCC-4
• Wrapping them up with OSG
• UOSPCC ? user analysis facilities
• 64bit cluster 32 bit cluster

Conclusion

• CERN-CMS, US-CMS, CMS-HI, MIT, all are strongly
  supporting Korean CMS-HI team
• Univ. of Seoul and Seoul local government are
  investing for computing resources
• Specialized man powers are ready to work
• Hope KISTI become the national center and we want
  to be plugged in.
• Hope to use KISTI Supercomm 4 too.
• KREONET GLORIAD are absolutely necessary, now!
