=head2 Compression
|
||||
|
||||
B<--compress> compresses the data in the temporary files. This is a
|
||||
bit tricky because there should be no files to clean up if GNU
|
||||
B<parallel> is killed by a power outage.
|
||||
|
||||
GNU B<parallel> first selects a compress program. If the user has not
|
||||
selected one, the first of these that are in $PATH is used: B<lzop
|
||||
pigz pxz gzip plzip pbzip2 lzma xz lzip bzip2>. They are sorted by
|
||||
speed on a 8 core machine.
|
||||
|
||||
Schematically the setup is as follows:
|
||||
|
||||
command started by parallel | compress > tmpfile
|
||||
cattail tmpfile | uncompress | parallel
|
||||
|
||||
The setup is duplicated for both standard output (stdout) and standard
|
||||
error (stderr).
|
||||
|
||||
GNU B<parallel> pipes output from the command run into the compress
|
||||
program which saves to a tmpfile. GNU B<parallel> records the pid of
|
||||
the compress program. At the same time a small perl script (called
|
||||
B<cattail> above) is started: It basically does B<cat> followed by
|
||||
B<tail -f>, but it also removes the tmpfile as soon as the first byte
|
||||
is read, and it continously checks if the pid of the compress program
|
||||
is dead. If the compress program is dead, B<cattail> reads the rest of
|
||||
tmpfile and exits.
|
||||
|
||||
As most compress programs write out a header when they start, the
|
||||
tmpfile in practice is unlinked after around 40 ms.
