Subject: GNU Parallel 20150722 ('Pluto') released [stable]

GNU Parallel 20150722 ('Pluto') [stable] has been released. It is available for download at: http://ftp.gnu.org/gnu/parallel/

No new functionality was introduced so this is a good candidate for a stable release.

Haiku of the month:

  Multi cores I see.
  Doing nothing. I say no!
  Use GNU Parallel.
      -- Ole Tange

New in this release:

* If a record fits in a block, --block only reads upto the size of --block. If not: --block reads a full --block more.

* Due to widely spread distributions still using --tollef even after a year of being retired following a year of being obsolete, --tollef now gives an error unless used with --gnu.

* --nice now uses a perl wrapper instead of the nice command.

* Cookie 2013-08-18 was won by Mark Maimone, 1 year and 11 months after release.

* A parser for GNU Parallel --joblog files: https://github.com/harryjubb/joblog

* GNU Parallel was cited in: Dynamical formation & scattering of hierarchical triples: Cross sections, Kozai-Lidov oscillations, and collisions http://arxiv.org/pdf/1507.03593.pdf

* GNU Parallel was cited in: A Fast Compiler for NetKAT http://arxiv.org/pdf/1506.06378.pdf

* GNU Parallel was cited in: Flexible Modeling of Epidemics with an Empirical Bayes Framework http://www.stat.cmu.edu/~ryantibs/papers/empbayes.pdf

* GNU Parallel was cited in: Decomposing Time-Lapse Paintings into Layers http://cs.gmu.edu/~ygingold/timemap/Decomposing%20Time-Lapse%20Paintings%20into%20Layers%20(Tan%20et%20al%202015%20SIGGRAPH)%20600dpi.pdf

* GNU Parallel was used in: Somatic mutation calling from the matched tumor-normal exome-sequencing http://fafner.meb.ki.se/biostatwiki/somac/

* Parallel Processing from the Command Line https://www.perpetual-beta.org/weblog/parallel-processing-from-the-command-line.html

* Using GNU Parallel to speed up network operations http://vielmetti.typepad.com/vacuum/2015/06/using-gnu-parallel-to-speed-up-network-operations.html

* Crawl faster with "parallel" - but how fast? http://andreas-wpv.blogspot.com/2015/07/crawl-faster-with-parallel-but-how-fast.html

* Simultaneously benchmark many URLs with ApacheBench and GNU parallel https://www.simonholywell.com/post/2015/06/parallel-benchmark-many-urls-with-apachebench/

* Bug fixes and man page updates.

GNU Parallel - For people who live life in the parallel lane.


= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job is can be 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. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.

If you use xargs and tee 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. GNU Parallel can even replace nested loops.

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.

You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/

You can install GNU Parallel in just 10 seconds with: (wget -O - pi.dk/3 || curl pi.dk/3/) | bash

Watch the intro video on http://www.youtube.com/playlist?list=PL284C9FF2488BC6D1

Walk through the tutorial (man parallel_tutorial). Your commandline will love you for it.

If you like GNU Parallel:

* Give a demo at your local user group/team/colleagues
* Post the intro videos on Reddit/Diaspora*/forums/blogs/ Identi.ca/Google+/Twitter/Facebook/Linkedin/mailing lists
* Get the merchandise https://www.gnu.org/s/parallel/merchandise.html
* Request or write a review for your favourite blog or magazine
* Request or build a package for your favourite distribution (if it is not already there)
* Invite me for your next conference

If you use GNU Parallel for research:

* Please cite GNU Parallel in you publications (use --bibtex)

* (Have your company) donate to FSF https://my.fsf.org/donate/


= About GNU SQL =

GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.

The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

When using GNU SQL for a publication please cite:

O. Tange (2011): GNU SQL - A Command Line Tool for Accessing Different Databases Using DBURLs, ;login: The USENIX Magazine, April 2011:29-32.


= About GNU Niceload =

GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.
