    • It's REALLY just a timing issue that hits an IO forwarding issue. - NOT backported.
    • Add an item to the NEWS that we (v3.0) ARE now compatible with libevent 2.1.8

Review Master Master Pull Requests

  • Does appear we have a number of PMI install failures on master.
    • Perhaps could have been fixed, since it's dated on the 12th. Cisco / Absoft.
      • 'nm_check_prefix' - this test requires an ENV to run. There is a directive in Makefile.am to run.
        • This test is used to report exported symbols that shouldn't be exported.
        • For some environments this check isn't working. Will get Mark to look at again.
        • Mark (IBM) will look at.
    • gds_dstore in PMIx - compile error. Undefined reference to opal_atomic.
  • Something is missing in hwloc tarball - missing netloc
  • libpmix failed in linking against libopal.
    • Ralph will look at these.
