Benchmark End (Memory Monitoring) (3 ports)

Vernalis benchmarking nodes version 1.20.5.v201908130849 by Vernalis (R&D), UK

This node provides the end of a timing block for monitoring performance of a node or nodes. It needs to be paired with a corresponding Performance Monitoring Timing Start (Memory monitoring) node. The node passes through the last iteration's occurrence of the input tables. An additional flow variable port with the following variable is added:

  • Overall Start Time
  • Overall End Time
  • Number of executions
  • Best execution time
  • Worst execution time
  • Total execution time
  • Mean execution time

A second table is added with the details of individual timings

A third table is added with the details details of memory usage

The incoming Datas are passed through unchanged from the final loop iteration

Execution can be halted either by the number of executions in the loop start node being passed, or the optional timeout time (again from the loop start node) being passed.

NB The timeout will not halt intermediate node execution, only prevent a new iteration starting.

This node was developed by Vernalis Research. For feedback and more information, please contact knime@vernalis.com
