there are couple computer manner questions.
Assume the couple manner IDs listed here bear a prevalent niceness appreciate of 0. What is crime with the aftercited order? renice -n 10 12345 23456 O You can solely renice individual manner, this tries to renice couple manneres O You cannot breed their niceness appreciates, solely inferior them Since the order is changing couple manneres, you insufficiency to supplement-p anteriorly the PIDs All of these are problems Nindividual of the overhead, this order has no problem
Defense 1: Since the order is changing couple manneres, you insufficiency to supplement -p anteriorly the PIDs
renice -n 10 12345 23456
‘renice’ order is used to vary scheduling priorty of individual or further running manneres.
’10’ is the innovating initiative. Scheduling initiative resides withing ramble of -20 to +19
Since couple manner IDs are to be reniced contemporaneously so -p has to be used anteriorly each of the PIDs couple denote there are couple PIDs whose scheduling priorities are to be varyed.
Defense 2: The CPU is spending 3.9%sy of its occasion on meat manneres
‘sy’ denotes meat space
In apex, CPU utilization can be mild down as aftercited :
