Shore-MT: A Scalable Storage Manager for the Multicore Era

News

11/6/2009: NEW Patched release of both shore-mt and the shore-kits available (see download page).

  Shore-MT
  • Fixed a log undo error due page marks not checking for the undo operating mode
  • Fixed an assertion failure due to page cleaners setting an invalid rec_lsn
  • Log now uses ringbuf_log::floor2/ceil2 as intended (instead of libc floor/ceil)
  Shore Kits
  • Clients now pause during checkpoints (reduces checkpoint duration in disk-bound systems)
27/5/2009: The shore-mt mailing list is working. Follow instructions here.

24/5/2009: Shore-MT and Shore-Kits code is out. Current release compiles only on Solaris 2.10 and sparc v9.

Who are we?

Shore-MT was developed by the members of the DIAS Laboratory at EPFL, Switzerland, as well as the StagedDB/CMP project group at Carnegie Mellon University. Many thanks as well to the excellent work done at the University of Wisconsin to produce the original SHORE!

Goal

The database research community needs a full-featured storage manager which can scale to utilize today's highly parallel multicore hardware. Shore-MT has provided us this functionality and we want other researchers to benefit from it as well.
