  • "STXXL implements containers and algorithms that can process huge volumes of data that only fit on disks." Close, but my data doesn't even fit on disk.
  • mergesort example - "It is assumed that each line of the file contains a word and is no more than 31 characters in length"
  • K-Way Merge - Dead google code repo.
  • externalsortinginjava - Ehhh, java.
  • pennysort/judyarrays - Another dead google code repo.
  • sortbenchmark.org - Fascinating but they all seem to be for weird synthetic data sets.
