I run measurements on a cluster consisting of 32 nodes/machines. I do not require all nodes, only 4, for example. The problem is most of the time, the nodes are busy with other people running their heavy job on them. So, to find idle nodes to get good results, I run the
top command on each machine starting from the first until I find 4 free ones.
Is there a way to test the cpu load/utilisation on multiple machines at once and if possible, listing those machines that are less busy?
