Table 2 Algorithm variables
From: TMaR: a two-stage MapReduce scheduler for heterogeneous environments
Variable | Description |
|---|---|
\(Res_{min}\) | Resource on which the execution time of Reduce Tasks is minimized |
\(R_F\) | Reduce tasks finish time |
\(R_S\) | Reduce task start time |
\(R_E\) | Execution time of Reduce tasks |
min | Temporary variable to hold minimum of Reduce tasks finish time related to a partition hosted on a node |
\(N_R\) | Number of Reduce tasks |
\(N_{Res}\) | Number of resources of the cluster |
\(R_{split}\) | System parameter which determines the number of Reducers required for a partition |
