Reports from Resource Breakout

PRAGMA 16KISTI, Korea

1st day• Review current status of PRAGMA Grid

(30 min)– Reports from two applications.

• e-Airs by Kum Won– Single job -> multi (parallel ) job– Need a Job scheduler– Network bandwidth problem– Remote compile– Interoperation between EGEE v.s. PRAGMA v.s. … OSG…

• Povray w/ Ninf-G by Yoshio– Issues discussed and introduced

• Globus port range– Will have common range

• PRAGMA/IGTF CA distribution

1st day (cont’d)

• PRAGMA Data Grid (20 min)–Updates of Gfarm 2–How we should move forward?

• Avian Flu on PRAGMA Data Grid is ongoing.

• Look for a report in PRAGMA17

1st day (cont’d)• Two talks from Korean researchers followed by open

discussions (70 min)– Data Center at KISTI (Dr. Bubkyun Kim)– Metadata Catalog (Dr. Soonwook Hwang)

• Discussed EGEE-PRAGMA Interoperation– KISTI will lead this.– KISTI will assign a representative.– Cindy will help to find the other sites interest in

this interoperation.– Xen/Rocks provisioning system may be a solution.

2nd day: VOMS on PRAGMA Grid• VOMS server and a PRAGMA VO are ready.• Existing groups

– Avian Flu– Nimrod – PRAGMA – PRIME– e-AIRs (will be created)

• Current VOMS-aware resource– BeST Grid (NZ), AIST, SDSC, iHPC– Installed PRIMA/GUMS– VOMS-enabled GT2/4 GRAM, GridFTP, gsissh– Documents for users and admins are available on

PRAGMA Wiki

2nd day: VOMS on PRAGMA Grid (cont’d)• Name of the VO

• Continue to use PRAGMA VO• Mapping rule

• Discussion• Shared account v.s. pool accounts• Static accounts and/or dynamic accounts

• Decision• Confirm if shared account violates IGTF requirements• Confirm if a mapping to pool account is permanent or not.• Then, decide the mapping rule as a resource WG.

• Certificate profiles of experimental CAs.• Some experimental CAs are using inappropriate profile

(email, userid, etc. in Subject Name).• Ask such CAs to change the profile.• Figure out which experimental CA uses inappropriate

profiles (Cindy)

2nd day: Virtual Clusters• For Rocks users in PRAGMA

– Can create virtual machines– Can create virtual clusters

• Demonstration of virtual cluster running on two physical clusters at UCSD

• Next UCSD PRAGMA Resources will all be virtual clusters– VDT on one– GT4 on another

• Next steps– Identify interested applications for VC– Attempt VC extension over PRAGMA
