1.free This command is used to view the current system memory usage, which can display the remaining and used physical memory, swap memory, shared memory, and kernel buffers in the system. 2. Shutdown This command is used to shut down or enter a single maintenance mode. The 3.data Data command can display the date and time of the current system. The clock command can also be used to display the current date and time of the system (by default, ordinary users cannot perform the clock command and must log on with the root account). For example: [Root@teache ...

MOSIX is a clustered operating system for high-performance Linux clusters, multiple clusters, GPU clusters, and cloud computing clusters. MOSIX supports interactive processing and batch processing. It incorporates automatic resources and dynamic assignment workloads, typically running on a single computer with multiple processors. The core of MOSIX's work is the adaptive Resource Management algorithm, which monitors the load of each node and responds accordingly, thus improving the overall performance of all processes. It uses preemptive process migration methods to allocate and redistribute processes across nodes to make the most of the ...
