Description du projet

GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. 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. 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.

--tralala-wrap permet aujourd'hui de paralléliser les scripts en mettant « parallèle » dans la ligne de shebang (le premier #! ligne dans les scripts).

--délai ajoute un retard après le début de chaque travail (utile pour éviter les raceconditions et les problèmes de troupeau tonitruantes).

--résultats maintenant utilise « / » comme séparateur au lieu d'onglet et crée ainsi des sous-répertoires.

Détection CPU OpenBSD est désormais effectuée.

niceload--capteur permet des nombres négatifs indiquer un nombre inférieur, ce qui signifie que la limite est plus faible.

niceload--prg interrompt un programme nommé qui est déjà en cours d'exécution.

niceload multiples--pid suspend les identifiants de processus qui sont déjà en cours d'exécution.
--shebang-wrap now makes it possible to parallelize scripts by putting
"parallel" in the shebang
line (the first #! line in scripts).

--delay adds a delay after starting each job

(useful to avoid raceconditions and thundering herd problems).

--results now uses "/" as a separator instead of TAB, and thus creates
subdirectories.

OpenBSD CPU detection is now performed.

niceload --sensor allows negative numbers to signify a lower number,
meaning the limit is lower.

niceload --prg suspends a named program which is already running.

niceload multiple --pid suspends process ids which are already running.
