chirp_stream_files - move data to/from chirp servers in parallel

Description

chirp_stream_files  is a tool for moving data from one machine to and from many machines, with the option
       to split or join the file along  the  way.   It  is  useful  for  constructing  scatter-gather  types  of
       applications on top of Chirp.

       chirp_stream_files  copy  duplicates  a  single file to multiple hosts.  The <localfile> argument names a
       file on the local filesystem.  The command will then open a connection to the following  list  of  hosts,
       and stream the file to all simultaneously.

       chirp_stream_files split divides an ASCII file up among multiple hosts.  The first line of <localfile> is
       sent to the first host, the second line to the second, and so on, round-robin.

       chirp_stream_files  join collects multiple remote files into one.  The argument <localfile> is opened for
       writing, and the remote files for reading.  The remote files are read line-by-line and  assembled  round-
       robin into the local file.

       In all cases, files are accessed in a streaming manner, making this particularly efficient for processing
       large files.  A local file name of - indicates standard input or standard output, so that the command can
       be used in a pipeline.

Examples

       To copy the file mydata to three locations:

               % chirp_stream_files copy mydata server1.somewhere.edu /mydata
                                                server2.somewhere.edu /mydata
                                                server2.somewhere.edu /mydata

       To split the file mydata into subsets at three locations:

               % chirp_stream_files split mydata server1.somewhere.edu /part1
                                                 server2.somewhere.edu /part2
                                                 server2.somewhere.edu /part3

       To join three remote files back into one called newdata:

               % chirp_stream_files join newdata server1.somewhere.edu /part1
                                                 server2.somewhere.edu /part2
                                                 server2.somewhere.edu /part3

Exit Status

       On success, returns zero.  On failure, returns non-zero.
