by Hartmut Fichtel

The annual 1998 CUG conference was jointly organized by the computer center of the University of Stuttgart (RUS) and the Debis Systemhaus (debis), the computer services company of the Daimler-Benz group.

The conference took place in downtown Stuttgart, the capital of the federal state of Baden-Wuerttemberg -- also well known for its fine local red and white wines. (Formerly these state products used to be somewhat difficult to purchase outside the state, since the local people managed to drink them all by themselves; but recently this has changed to some extent. All the attendees I talked to survived this local specialty nicely!)


SGI, site reps give technical sessions

For this conference, as usual, the Mass Storage Systems (MSS) Special Interest Group (SIG) sponsored nine presentations in three technical sessions during the parallel stream of the program. About half the talks were presented by SGI staff, and the other half by representatives from user sites.

GigaRing IO considerations and DMF or other high-performance HSM systems dominated the subject matter of the talks. Attendance was typically so good that the rooms were filled to the limit of their capacity.

A summary of titles and authors follows; for the complete paper, as always, please refer to the CUG Proceedings CD.

Tuesday afternoon

  • "GigaRing Mass Storage Update" -- Michael Langer, SGI
  • "Performance Tips for GigaRing Disk IO" -- Kent Koeninger, SGI
  • "Cray DMF and Tape-Management Facility Update" -- Neil Bannister, SGI

Wednesday afternoon

  • "High-Performance Network Backup and Restore with HYPERTape" -- Aindrias Wall, MultiStream Systems (presented by Uwe Olias, University of Kiel)
  • "Functional Comparison of DMF and HPSS" -- Gerhard Rentschler, RUS
  • "The Rebirth of DMF on IRIX" -- Alan Powers, NAS

Thursday afternoon

  • "Mass Storage at the NCSA: DMF and Convex UniTree" -- Michelle Butler, NCSA (presented by Jeff Terstriep, NCSA)
  • "Towards Petabytes of High Performance Storage at LANL" -- Gary Lee, LANL
  • "Storage and Data Management: Big Data Solutions" -- Ken Hibbard, SGI (presented by Neil Bannister, SGI/Cray)

On behalf of the audience and the MSS SIG, I thank each of the authors and speakers for their excellent work.


Open meetings dominated by SIG restructuring

As usual, there were two open meetings of the MSS SIG during the conference: the first at the beginning of the conference (Monday) to survey possible problems and concerns in the area of mass storage, and the second towards the end (Thursday) to have these issues adressed by SGI staff and hopefully resolved. At least that was the plan!

Actually, the major restructuring of the SIGs overwhelmed all specific MSS-related technical concerns. During the first business meeting slot on Monday, most of the time available was taken up by a general-session meeting with a discussion of these plans by the membership as a whole.

After this general meeting, an ad-hoc MSS business meeting took place to discuss the specific MSS-related consequences of the proposed new structure. In general, members responded positively to the proposals.

The second MSS business meeting on Thursday afternoon was similarly used up by a general-membership open meeting to present the decisions from the CUG Board of Directors on the proposed structure changes. (For details on the restructuring, see "CUG SIGs get a facelift" and A guide to the new CUG SIGs.")

As part of the restructuring, the MSS SIG will now be called the MSS Focus Group and reside under the new Communications and Data Management "super" SIG.


Chair changes

After mastering all the work to compile the technical presentations of the MSS SIG, Robert Silvia had to resign as chair due to changes in his job position at North Carolina Supercomputer Center. I would like to thank Rob for his support of CUG and all his work in setting up the technical program for this conference. I still look forward to seeing him at future CUGs.

Jeff Terstriep has been selected and approved by the board as chair of the new MSS Focus Group.
