Lucas Zampieri from Red Hat published a humorous task scheduler scx_horoscope, distributing CPU resources based on astrological principles, taking into account zodiac signs and the current positions of planets. The project is being developed for educational and entertainment purposes. The primary aim of scx_horoscope is to teach and demonstrate the use of the «sched_ext» (SCX) mechanism, which allows using eBPF to create CPU schedulers. <\/p>\n
The scheduler is fully operational and quite stable, but it is not recommended for production use, as it indeed takes into account the retrograde motion of planets and lunar phases when calculating process priorities. The astro package is involved for accurate planetary positioning. <\/p>\n
Tasks are classified according to zodiac signs and celestial bodies, for example, the sun is linked to critical processes (PID 1, init), the moon with interactive tasks (editors, command shells, terminal emulators), mercury with network tasks and input\/output, venus with desktop tasks, mars with resource-intensive applications (compilers, video encoders), jupiter with memory-hungry processes (DBMS, browsers), and saturn with system background processes and kernel threads. <\/p>\n
When there are negative astrological influences from the planetary positions calculated for the current day, a 50% reduction in priority is applied to the tasks associated with that planet. For example, during retrograde Mercury, the priority for network and interactive tasks is decreased, during retrograde Mars \u2014 for resource-intensive tasks, and during retrograde Venus \u2014 for desktop tasks. <\/p>\n
The current phase of the moon also affects priority \u2014 during a full moon, interactive tasks receive 1.4 times more time. Fire and air zodiac signs increase the priority of CPU-consuming tasks by 1.5 times, but decrease the priority of memory-intensive tasks by 0.7 times. Water signs reduce the priority of CPU tasks by 0.6 times but increase the priority of memory-consuming tasks by 1.3 times. <\/p>\n
