      Moves the tag reservation to MPI layer · bb755b5c
      Wesley Bland authored and Pavan Balaji's avatar Pavan Balaji committed
      Resets MPIDI_TAG_UB back to 0x7fffffff. This value was changed a while back,
      but the change should have happened at the MPI layer instead of the CH3 layer.
      This resets the value to allow CH3 to use the tag space.
      Instead, the value is now set in the MPI layer during initthread. This means
      that it will be safe regardless of the device being used. This prevents a
      collision that was occurring on the pamid device where the values for
      MPIR_TAG_ERROR_BIT and the MPIR_Process.attr.tagged_coll_mask values were the
      Fixes #2008

      Revert "a partial round of datatype optimizations" · 7a9a46fb

      This reverts commit 38ef5818.
      the MPICH-1 and Intel tests found unexpected results with these
      optimizations.  Will explore later.

      Time iterations and break out if we are too slow. · 29c8529f
      Pavan Balaji authored
      On some machines the iterations take unusually long.  If they are
      getting to be larger than a predefined amount, break out of that loop.
      Fixes #1669.

      Simplify logic in compile wrapper scripts. Use configure substitutions
      where possible to better match pkg-config style.

      Includes the following modifications by Pavan Balaji:
      Remove the PAC_COMPILER_SHLIB_FLAGS usage, instead of modifying the
      macro in confdb.
      The ordering of flags in mpicc and friends does not match that of
      pkg-config.  This is because of two reasons.
      1. pkg-config reorders flags when it outputs them.  This requires us
      to manually adjust the flags in mpicc to match up, and is error prone.
      2. mpicc and friends provide LDFLAGS before the user-specified flags,
      followed by the include and library directories.  This is to make sure
      that the LDFLAGS are listed before the application source file.
      Reordering them to match pkg-config loses this flexibility.

      a partial round of datatype optimizations · 38ef5818
      Rob Latham authored
      Some datatype performance tests in the MPICH test suite fail:
      (perf/twovec,  perf/nestvec, perf/nestvec2, perf/indexperf,
      This changeset introduces a few optimizations that operate on the
      dataloop representation to make it more performant.  perf/indexperf
      should still fail under these changes.
      Original-author: Bill Gropp <wgropp@illinois.edu>
      See #1788, for which this resolves some but not all performance issues.

      Fix bogus datatype perf test · 4e1b470d
      William Gropp authored
      The test in test/mpi/perf/twovec made invalid assumptions about the
      performance of two MPI datatype creation routines.  This is a hard test to
      get right, but this version is more likely to avoid falsely signalling
      an error.

      Comment out nb_test, since it's not entirely correct. · cf551af4
      Pavan Balaji authored
      This was meant to test out the case when MPI_Test is not nonblocking.
      However, we ended up assuming that MPI_Win_lock will be nonblocking.
      That is not specified by the standard and might not be true.
      Commenting this out till be find a better way to test the original
      problem with MPI_Test.
      Fixes #1910.
