Cluster With Functional Heterogeneity Of Nodes With Requests Of Different Criticality to Delays

Cluster systems combining nodes that are heterogeneous in functionality are considered. The probability of timely execution of a flow of requests heterogeneous in functionality, differing in the allowable waiting time in queues, is estimated. The evaluation is presented for the functional configuration options of cluster nodes. The area of efficiency of reservation of latency-critical requests is determined depending on the intensity of the total input stream.
