If some tasks get a lot more CPU time than others, the result is likely to be unhappy users. Vincent Guittot ran a session at the 2020 Power Management and Scheduling in the Linux Kernel summit (OSPM) looking into this issue, with a focus on detecting load imbalances between CPUs and what to do with a workload that cannot be balanced....

    vom 231.91 Punkte ic_school_black_18dp
    AutoRecon is a multi-threaded network reconnaissance tool which performs automated enumeration of services. It is intended as a time-saving tool for use in CTFs and other penetration testing environments (e.g. OSCP). It may also be useful in real-world engagements. The tool works by firstly performing port scans/service detection scans. From those initial results, the tool will launch further enum
