  abstract = {This paper presents the design and evaluation of a multi-threaded
  runtime library for parallel I/O. We extend the multi-threading concept to
  separate the compute and I/O tasks in two separate threads of control.
  Multi-threading in our design permits a) asynchronous I/O even if the
  underlying file system does not support asynchronous I/O; b) copy avoidance
  from the I/O thread to the compute thread by sharing address space; and c) a
  capability to perform collective I/O asynchronously without blocking the
  compute threads. Further, this paper presents techniques for collective I/O
  which maximize load balance and concurrency while reducing communication
  overhead in an integrated fashion. Performance results on IBM SP2 for various
  data distributions and access patterns are presented. The results show that
  there is a tradeoff between the amount of concurrency in I/O and the buffer
  size designated for I/O; and there is an optimal buffer size beyond which
  benefits of larger requests diminish due to large communication overheads.}
