cpulimit-like program for more than process.
I have a program with starts several child processes (GraphicsMagic), which each starts GhostScript subprocess, which eats cpu and together overheats my tiny laptop, which reboots.
mcpulimit [OPTIONS] [executable names]
-l=50: the percent (between 1 and 100) to limit the processes CPU usage to
-t=0: timeout (seconds) to exit after if there is no suitable target process (lazy mode)
The executable must be full paths if the executable is not found in PATH.
mcpulimit sends SIGSTOP
and SIGCONT
signals to the processes, thus you
need to have permission for this - but practically if mcpulimit runs as the
same user as the processes to be limited, no problems araise.
go install github.com/tgulacsi/mcpulimit
Go compiler and an operating system with /proc
filesystem, and SIGSTOP
and SIGCONT
signals.
