AVER is the increased ratio of AVE of CPLMT to AVE of CMMS;
FJR is the enhanced ratio of the number of finished jobs of CPLMT to the number of finished jobs of CMMS.
If the value of ratt is less than 1, it means that, to CMMS, the enhanced ratio of the number of finished jobs of CPLMT is more than the increased ratio of AVE, so it worth using more time for the job.
CPLMT always has the largest value in all the five methods, and followed by Fair and FIFO.
CPLMT performances well in parallel scheduling because: (1) it takes account of the requirement of tasks; (2) it takes account of the attributes of the VM; (3) the job with only a few VMs can satisfy are scheduled first; (4) the job with shorter execution time be scheduled first.
CPLMT has the lowest value in UFJ, AWT and SIN, at the same time, CPLMT has a middle value in AVE.
