G1: implement +UseNUMA for G1

    Details

    • Subcomponent:
      gc
    • CPU:
      generic
    • OS:
      generic

      Description

      We should port the NUMA allocator from ParallelGC to G1 to improve G1's performance on NUMA architectures. The high-level idea is to have a pool of G1 regions associated with each lgroup and one allocating region per lgroup. So, at the point of slow path allocation (i.e., when allocating a new TLAB or an object outside a TLAB) we should decide which current allocating region to allocate out of.
