[Wien] How to free the memory after a parallel session?

[sayede adlane]

The top command can give you up-to-the-second
reporting of system load, memory usage, and CPU
utilization. It is distributed as part of the procps
package. You can monitor Memory usage (RES) with N,
CPU usage with K, and kill a Process (to free memory)
with k.
