  abstract = {We present two designs, namely, "collective I/O" and "pipelined
  collective I/O", of a runtime library for irregular applications based on the
  two-phase collective I/O technique. We also present the optimization of both
  models by using chunking and compression mechanisms. In the first scheme, all
  processors participate in compressions and I/O at the same time, making
  scheduling of I/O requests simpler but creating a possibility of contention
  at the I/O nodes. In the second approach, processors are grouped into several
  groups, overlapping communication, compression, and I/O to reduce I/O
  contention dynamically. Finally, evaluation results are shown that
  demonstrates that we can obtain significantly high-performance for I/O above
  what has been possible so far}
