  abstract = {Parallel file systems employ data declustering to increase I/O
  throughput. As a result, a single read or write operation can generate
  concurrent data accesses on multiple storage devices. Unless a concurrency
  control mechanism is employed, familiar file access semantics are likely to
  be violated. This paper details the transaction-based concurrency control
  mechanism implemented in the PIOUS parallel file system. Performance results
  are presented demonstrating that sequential consistency semantics can be
  provided without loss of system scalability.},
  comment = {They describe {\em volatile transactions\/} as a way of providing
  the appopriate sequential consistency among file-read and -write operations
  (a feature not provided by most file systems). Their PIOUS library implements
  these transactions with strict 2-phase locking. They show some performance
  results, though only on a limited and relatively simple benchmark. If nothing
  else this paper reminds us all that atomicity of file-read and -write
  requests should be available to the user (eg, note how they are optional in
  Vesta). Published as moyer:scalable.}
