Ack as long as 1.4.3 comes out before 6.1 package freeze. ------- Comment From rsisk.com 2010-10-04 10:36 EDT------- Code Upstream Status: Accepted ------- Comment From brad.benton.com 2010-11-04 16:39 EDT------- Open MPI 1.4.3 was released on 10/5/2010. It can be downloaded from: http://www.open-mpi.org/software/ompi/v1.4 *** Bug 636627 has been marked as a duplicate of this bug. *** This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. This request has been proposed for the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. ------- Comment From brad.benton.com 2011-01-10 22:27 EDT------- Here is a list of fixes that are in the Open MPI 1.4.3 release which IBM views as crucial for Power systems: - Fixed problems in processor affinity support, including when there are "holes" in the processor namespace (e.g., offline processors). [IBM COMMENT] This is especially crucial for IBM & the Power architecture so that the user has control over process affinity, particularly on P7 with its multiple SMT modes. - 1.4.3 has the re-licensed LoadLeveler code from IBM such that it is now compliant with the BSD license. [IBM COMMENT] Resolution of this licensing issue was required by Red Hat - Numerous fixes in support of MPI_THREAD_MULTIPLE [IBM COMMENT] We currently have a customer for which this is crucial - Fixed an incorrect branch in some ppc32 assembly code. [IBM COMMENT] This error was discovered in the field, so already has an applicable customer use case & requirement for fixing - Numerous bug fixes for both stability and correctness [IBM COMMENT] While not an IBM-only requirement, these improvements benefit the community as a whole Question: RHEL6.0 includes Open MPI 1.4.1. What is currently in plan for 6.1? 1.4.1 or 1.4.2? This enhancement request was evaluated by the full Red Hat Enterprise Linux team for inclusion in a Red Hat Enterprise Linux minor release. As a result of this evaluation, Red Hat has tentatively approved inclusion of this feature in the next Red Hat Enterprise Linux Update minor release. While it is a goal to include this enhancement in the next minor release of Red Hat Enterprise Linux, the enhancement is not yet committed for inclusion in the next minor release pending the next phase of actual code integration and successful Red Hat and partner testing. @IBM, Could you test this request with rhel6.1 beta bits openmpi-1.4.3-1.1.el6? and post your test feedback here. Thanks.

~~ Partners and Customers ~~ This bug was included in RHEL 6.1 Beta. Please confirm the status of this request as soon as possible. If you're having problems accessing 6.1 bits, are delayed in your test execution or find in testing that the request was not addressed adequately, please let us know. Thanks! ------- Comment From brad.benton.com 2011-04-21 15:52 EDT------- I tested openmpi-1.4.3-1.1.el6 from 6.1beta on both x86_64 and ppc64 platforms. Shared memory, TCP/IP, and InfiniBand were the tested transports. All tests (NPB) ran to completion and the computational results were successfully verified. So, this looks good. Marking partner Verified per IBM feedback. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHEA-2011-0590.html |
