Parallelize Memory Pretouch

XMLWordPrintable

    • gc
    • b139

      On large machines (1 TB heap), pretouching the heap takes around 10mins.
      Considering that we are aiming for even larger heap, that is too slow.
      There are some indications that there is potential for improvements if parallelized.

      Investigate this.
