For reading files, the filename may begin with ftp:// or http:// and/or end with .gz; in this case file is brought over and uncompressed.
For creating files, if the file name ends with .gz it is automatically compressed when closed.
For writing files it only opens the file on processor 0 in the communicator. For readable files it opens the file on all nodes that have the file. If node 0 does not have the file it generates an error even if other nodes do have the file.
