If you sort the chunks while generating, then apply the n-way merge as described—that full procedure results in a 100GB write, plus another 100GB of reads and 100 GB of writes. In total, 300GB of streaming (external memory access).

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
