The meeting summary is also avilable on the Wiki:
https://wiki.openfabrics.org/tiki-index.php?page=Teleconf+01-15-2007

*Abbreviated minutes / summary*

    * OFED 1.2 components readiness for end of January code freeze: In
      general most packages will be ready on time.
      Some features will be added after the Alpha but these will be
      add-ons that are not part of core/drivers/libraries and cannot
      harm stability of the package.
    * OFED 1.2 plan was updated on the Wiki:
      https://openib.org/tiki/tiki-index.php?page=OFED+1.2+release+plan+and+features

    * Decided to add MVAPICH2 package - OSU are the owners
    * Daily build update on the OFA server
    * Bonding module will be added to OFED 1.2 to support HA on older
      kernels
    * Toward the release each user level owner will open a branch (with
      the name ofed_1_2) to be used for the release sources


*Detailed Minutes*


      Build & integration process:

    * There is a daily build of all components on OFA server
    * User space - from all user space git trees
    * kernel.org starting from 2.6.12 till 2.6.19 (supporting kernel
      2.6.19 and 20 is required, the rest of kernel versions are optional)
    * Kernel cross compilation: X86_64, ia64, ppc, ppc64 (Vlad will send
      a mail)
    * Build mails will be sent every day starting this week
    * HOWTO was updated in WIKI home page:
          o HOWTO Build OFA user package
          o HOWTO Build OFA kernel package
          o HOWTO add userspace package to ofa_user


      General changes to the package:

    * Chelsio driver - on work - to be integrated this week
    * Re-base to kernel 2.6.20 to be done in few days
    * Sa cache - in ofed_1_2 today - Intel please test
    * Multicast - we wait for Voltaire and Sean to close all technical
      details - should be ready by the end of the week
    * SA async event support and InformInfo?
      <https://wiki.openfabrics.org/tiki-editpage.php?page=InformInfo>
      and Notice reporting - will be ready only first week of Feb
    * Bonding module - Voltaire are working to prepare back-port of the
      bonding module that will support HA for IPoIB in older kernels.
      The module should be ready by the end of this week
    * low level drivers - all going to be ready on time, except the new
      ehca interrupt handler


      Libraries:

    * libibverbs 1.1: (from Roland)
          o Fork support - done
          o Minor ABI extensions for new low-level drivers - done
          o Better low-level driver handling, including multiple drivers
            linked in statically - done
          o Dropped from OFED 1.2:
                + Memory windows
                + Reregister memory region (incl. extend without
                  unregister...)
                + libibverbs 1.0 to be included as well
    * Management: All the code is ready. Hal will prepare a release
      version for OFED 1.2.
    * CM/CMA: Sean will prepare a release version. Number will probably
      be 1.1 not to collide with existing libraries version in Redhat
    * uDAPL: Woody will ask Arlin to create a release for uDAPL library


      Kernel ULPs:

    * IPoIB:
          o Connected Mode - code ready and under testing now
          o NAPI - should test with CM - Mellanox. Current ehca
            interrupt handler does not working well with NAPI. IBM is
            working to change their interrupt handler to overcome this.
            Not clear if this will be ready on time.
    * SDP:
          o Netstat - done - under testing
          o Scalability - done
          o small messages BW - on work
    * iSER: Most changes are ready and integrated to ofed 1_2 git tree.
    * SRP: MPP integration for HA - we wait for new MPP driver from Engenio
    * RDS: Tziporet to approach Oracle to understand if the License
      issue going to be resolved till end of month.
    * VNIC - Integrated into ofed_1_2 git tree - Qlogic should test it


      Management:

    * OpenSM:
          o QoS - on work; first version will be ready at end of month
          o FAT tree routing - done
          o Taurus routing - done
          o SA InformInfo?
            <https://wiki.openfabrics.org/tiki-editpage.php?page=InformInfo>
            improvements and InformInfoRecord?
            <https://wiki.openfabrics.org/tiki-editpage.php?page=InformInfoRecord>
            support - done
          o SA database dump/restore - ?
          o Modular routing for multicast - ?
          o IB router enablement - done
    * Diagnostics:
          o Monitoring QoS - ?
          o Partitions analysis - ?
          o GUI tool - done
          o perfquery support for extended port counters - done
          o ibportstate enhancements to change link speed of a port - ?

*MPI*

    * MVAPICH 0.99 - Beta should be ready this or next week.
    * Open MPI 1.2 - Code in convergence. For the Alpha we will use a
      pre-release version but it will become stable for the Beta
    * MVAPICH2 0.9.8 - OSU (Shaun Roland) will be the owner in OFED and
      will provide the source RPM, based on the 0.9.8 release that was
      already done
    * Each MPI owner will open a git tree on the OFA server and locate
      the SRPM there.
