GNU Parallel 20101222 has been released. It is available for
download at: http://ftp.gnu.org/gnu/parallel/

New in this release:

* GNU niceload is now part of GNU Parallel. GNU niceload slows down a
program if the load average is above a certain limit.

* Implemented --tmpdir to buffer standard output and standard error in
a different place.

* Implemented --load to wait until the load is below a limit before
starting another job on that computer.

* Implemented --nice set the niceness of jobs running both locally and
remotely.

* Implemented --dry-run to print the job without running it.

* Review with focus on clusters. Thanks to Taylor Gillespie

* Review with focus on protein similarity.

* Review in Spanish.

* Quite a few bug fixes.

= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one
or more machines. A job is typically a single command or a small
script that has to be run for each of the lines in the input. The
typical input is a list of files, a list of hosts, a list of users, a
list of URLs, or a list of tables.

If you use xargs today you will find GNU Parallel very easy to use as
GNU Parallel is written to have the same options as xargs. If you
write loops in shell, you will find GNU Parallel may be able to
replace most of the loops and make them run faster by running several
jobs in parallel. If you use ppss or pexec you will find GNU Parallel
will often make the command easier to read.

GNU Parallel makes sure output from the commands is the same output as
you would get had you run the commands sequentially. This makes it
possible to use output from GNU Parallel as input for other programs.
