    If a dev build (SKIP_OAM_INIT), made postConfigure exit before trying
    to start the system, because that won't work.

commit 7b9a67df7d192f240e9e558e6e66c7aa9f1e8687
Author: Patrick LeBlanc <patrick.leblanc@mariadb.com>
Date:   Wed Sep 18 10:10:43 2019 -0500

    Checkpointing add'l optimizations.

    If we promote bpp::processorThreads / bucket count to a power of 2, we can
    use a bitmask instead of a mod operation to decide a bucket.

    Also, boosted utilization by not waiting for a bucket lock to become free.
    There are likely more gains to be had there with a smarter strategy.
    Maybe have each thread generate a random bucket access pattern to reduce
    chance of collision.  TBD.

    Multithreaded PM hash table construction likely works here.

    A couple more fixes.
     - missed a mod after a hash in one place.
     - Made the PoolAllocator thread safe (small degree of performance hit
       there in threaded env).  May need to circle back to the table
       construction code to eliminate contention for the allocators instead.

    Checkpointing.  First cut of multithreaded PM join table building.

    Builds but is untested.

commit b87039604e312c1ddb88cdb226228b1c3addf018
Author: Patrick LeBlanc <patrick.leblanc@mariadb.com>
Date:   Thu Sep 12 22:04:15 2019 -0500

    Checkpointing some experimental changes.

     - Made the allocator type used by PM joins the STLPoolAllocator
     - Changed the default chunk size used by STLPoolAlloc based on a few test
        runs
     - Made BPP-JL interleave the PM join data by join # to take advantage
        of new locking env on PM.
     - While I was at it, fixed MCOL-1758.

    Removed that limitation.

    Some optimizations to PM hash table creation.

    - made locks more granular.
    - reduced logic per iteration when adding elements.

4b9d046c6e Fully resolve potentially ambiguous symbols by removing using namespace statements from headers which have a cascading effect. This causes potential behavior changes when switching to c++11 since symbols can be exported from std and boost while both have been imported into the global namespace. 2019-04-29 01:21:15 -05:00

9363504dd4 MCOL-1847. Addressed feedback from Daniel.
Instead of a seperate param for cache size, we decided
to allow an override of the NumBlocksPct param instead.
If NumBlocksPct ends in an 'm' or a 'g', it will be interpreted
as megabytes or gigabytes instead of a %age.
