  abstract = {In out-of-core computations, data needs to be moved back and
  forth between main memory and disks during program execution. In this paper,
  we propose a technique called the Extended Two-Phase Method, for accessing
  sections of out-of-core arrays efficiently. This is an extension and
  generalization of the Two-Phase Method for reading in-core arrays from files,
  which was previously proposed in [Rosario93,Bordawekar93]. The Extended
  Two-Phase Method uses collective I/O in which all processors cooperate to
  perform I/O in an efficient manner by combining several I/O requests into
  fewer larger requests, eliminating multiple disk accesses for the same data
  and reducing contention for disks. We describe the algorithms for reading as
  well as writing array sections. Performance results on the Intel Touchstone
  Delta for many different access patterns are presented and analyzed. It is
  observed that the Extended Two-Phase Method gives consistently good
  performance over a wide range of access patterns.},
