used to interface with both the Redis and Disque brokers: $ pip install redis - Psutil [https://github.com/giampaolo/psutil] python system and process utilities module by Giampaolo Rodola', is an optional optional requirement and adds cpu affinity settings to the cluster: $ pip install psutil - Hiredis [https://github.com/redis/hiredis] parser. This C library maintained by the core Redis team is faster cpu_count] does not work. Installing psutil provides Django Q with an alternative way of determining the number of CPU's on your system - CPU affinity is provided by psutil which at this time does not support
