  comment = {This paper is not specifically about parallel I/O, but the file
  system will be used in the AP-1000 multiprocessor. Acacia is a file server
  that is optimized for synchronous writes, like those used in stateless
  protocols (eg, NFS). It writes inodes in blocks in any free location that is
  close to the current head position, using indirect inode blocks to track
  those. Indirect blocks are in turn written anywhere convenient, and their
  positions are tracked by the superblock. There is one slot in each cylinder
  reserved for the superblock, which is timestamped. They get good performance
  but claim to need a better implementation, and a faster allocation algorithm.
  No indication of effect on read performance.}
