A rough estimate would be about 2 weeks, although there are no

tuning a few parameters before releasing.

Hi Luke Yen

As you said "Full support for building apache, zeus, and jbb workload
checkpoints should be expected in a patch released shortly", can you please tell how short it is (I mean in #weeks)? I was eagerly looking for that.
Thanks,
Hemayet Hossain

GEMS users,

   The GEMS team has put its finishing touches on the new 2.0 release, and
it is now available for download at:

     http://www.cs.wisc.edu/gems/download.html

   Notable features of this release include:

      LogTM-specific features/updates:
         - single-chip transactional CMP directory protocol, with sticky-M
& sticky-S directory states
         - support for partial rollback, closed and open nesting
         - support for compensating and commit actions through our software
handler
         - "Perfect" Signature support (can emulate inifite RW bits)
             and Finite Signature support (Bit-Select & H3)
         - Summary signature support (Perfect & finite)
         - Limited LogTM-SE virtualization support, all in simulator*
         - support for ISCA '07 Pathologies systems:
               Eager conflict detection, Lazy version management
               Lazy conflict detection, Lazy version management
               Eager conflict detection, Eager version management, with &
without store-set prediction
               Hybrid conflict resolution policy
         - Sample transactional micro-benchmarks

       Please note that the prior SMP LogTM protocol using RW bits is no
longer supported in this release.  Finite RW bit (LogTM-like)
functionality can be emulated by using "Perfect" signatures & the released
CMP protocol.

      Non-LogTM specific features/updates:
         - x86 support for Ruby (Thanks Soohong Kim for the patch)
         - Simultaneous multi-threading (SMT) support in Opal
         - Protocol fixes
         - Bash scripts to automate generation of "naked/OS/whatever"
checkpoints**

    *  = We plan on integrating more stable support with OpenSolaris in the
future
    ** = Full support for building apache, zeus, and jbb workload
checkpoints should be expected in a patch released shortly.
