Есть несколько систем расписания (система управления нагрузкой). Как SGE (Sun Grid Engine), LSF, PBS. Обычно на рабочей станции с помощью команды qsub можно поместить задание в очередь, после чего система планирования возьмет на себя управление оттуда. У меня есть вопросы:
* Is 'qsub' a Unix command?
qsub is the binary used to submit jobs in SUN GRID ENGINE. Just like bsub in LSF
* How does qsub associate with a scheduling system? What does the system admin have to configure?
qsub associate 100% with the scheduling system. The system admin can configure from nothing "basic installation" to server resource, policies, esub, elims to define the rules on job launching.
* Which scheduling system is more popular?
Depends. When we tried SGE couple of years ago it had issues taking more than 10K jobs but now SGE improved a log. At that point we had to opt for Platform LSF, which is a paid scheduling system but works great for large clusters with good monitoring solutions.
